5. SPECIFICATIONS
5.1 Introduction
The zipSTOP Brake assembly is a controlled braking force device designed specifically for use in the zip line industry as a Primary or EAD at the end of zip line runs. The zipSTOP caters to a range of rider weights and approach speeds, and offers a smooth, consistent braking force for all riders. The brake is designed to be mounted to a primary and/or secondary anchor point to slow the decent of riders on a zip line. The primary anchor point is exactly what it sounds like; it is the main attachment point for the brake. The secondary anchor point is the support point for the redirection lines and pulleys.
The zipSTOP Brake Unit is installed at the end of the zip line, usually on or adjacent to the terminal end. A
Secondary Anchor Point is normally required upstream of the landing area to provide support for the Redirection Line pulleys. Alternately a full-length secondary cable of sufficient capacity can be installed to provide support for the Redirection Line and associated pulleys.
The design of the zipSTOP allows for simple installation, and incorporates both an advanced self-regulating brake unit and an automatic line reset. The patented braking mechanism delivers smooth deceleration and is designed to minimize variations in the deceleration rate and stopping distance of both children and adults.
There are no friction parts in the brake mechanism, ensuring reliability remains high while maintenance and operating costs are kept to a minimum.
Installation, inspection, operation and maintenance must be carried out in accordance with the instructions in this manual to protect the longevity of the zipSTOP components.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.

6. OPERATING PRINCIPLES
6.1 General
The zipSTOP Brake assembly is a controlled braking force device designed specifically for use as a Primary or
EAD at the end of zip line runs. The zipSTOP caters to a range of rider weights and approach speeds and offers a smooth, consistent braking force for all riders. zipSTOP Brake performance relies on operators using the correct equipment and operating the system in accordance with the instructions contained within this manual.
The zipSTOP Brake assembly consists of a zipSTOP Brake Unit, zipSTOP Brake Trolley, redirection pulleys and associated Redirection Lines.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.

Typical zipSTOP Installation
The zipSTOP Brake Unit is located at the zip line terminal end, normally adjacent to the landing area. It is connected via a redirection pulley and Redirection Line setup to the zipSTOP Brake Trolley.
The Brake Trolley is located on the zip line and when idle (zipSTOP Braking Line fully retracted) will be positioned at the start of the rider Arrest Zone (Reset Position). The approaching rider trolley contacts the Brake Trolley, moving it down the zip line. As the Brake Trolley moves into the Arrest Zone it extends the Braking Line out of the zipSTOP Brake Unit via the Redirection Line. As the Braking Line extends out of the zipSTOP Brake Unit, the eddy current brake in the unit is activated, controlling the rate of deceleration and slowing the rider in a smooth manner.
Once the load is removed from the Brake Trolley, the return mechanism in the zipSTOP Brake Unit retracts the Braking Line, automatically returning the Brake Trolley to the start of the Arrest Zone (Reset
Position) on the zip line, ready for the next rider.
When higher Redirection Ratios are employed retraction force is reduced and a manual reset of the Brake
Trolley may be necessary.
Ensure brake is reset before rider starts down zip line, every time.

7.9 Redirection Line
The Redirection Line is required to connect the zipSTOP Brake Unit to the Brake Trolley and will transfer the braking force from the Brake Unit. The Redirection Line passes through the redirection pulleys and must meet minimum specification. The following list provides several Redirection line options.
Head Rush Technologies developed the Gorilla Rope specifically for use as a redirection line with the zipSTOP
Zip Line Brake It features a high strength-to-weight ratio, is designed to be highly resistant to abrasion, UV resistant, and water repellent. The 6mm Gorilla Rope maximizes performance because it is lighter, smaller in diameter, minimizes resistance, and maximizes reliable reset.
Spectra - Spectra/Dyneema is one of the recommended materials because it has sufficient strength while minimizing size and diameter. Spectra/Dyneema is known for high strength and superior abrasion, water, and
UV resistance. The spectra line should be jacketed with an abrasion-resistant, temperature-tolerant material to avoid possible degradation of the line due to friction. Gorilla Rope, a Head Rush Technologies product, is designed specifically to provide high strength, a long life span, and minimal stretch for applications where a small diameter rope is necessary. It is made for maximum durability and high performance in any application.
It is perfect for use as a reduction line with the zipSTOP Zip Line Brake but can also be used for many other industrial or recreational applications where these qualities are critical.
Technora® - Technora, while the strongest of the synthetic fibers, is particularly sensitive to UV wear. Only
Technora core lines with UV protective jackets should be used. Technora lines are also slightly stiffer which can increase retraction drag when used as a Redirection Line. The drag is usually offset by the fact that a smaller diameter Technora line can be employed compared to another material.
20
Typical Technora Termination
Nylon and Other materials - Nylon or other materials can be used provided they meet the minimum requirements for strength, UV, and wear resistance. However, these lines may necessitate much larger diameter ropes to attain the necessary strength which can have an adverse effect on Redirection Line performance. www.headrushtech.com | +1-720-565-6885

ALWAYS USE THE SPECIFIED REDIRECTION LINE
Failure to utilize a Redirection Line of specified strength and quality can compromise zipSTOP brake operation, resulting in equipment damage, serious injury or death.
REDIRECTION LINE WILL BE SUBJECT TO WEAR AND ABRASION
Any Redirection Line selected for use will wear and must be replaced from time to time. Lines must be carefully inspected prior to use each day, and failure to do so may result in serious injury or death.
When selecting a Redirection line, the following considerations apply:
The line must meet the specifications described above.
A lighter, smaller diameter line is preferred, to minimize resistance and weight, and maximize reliable reset.
A waterproof line is required. Water absorption can add significant weight, allowing the line to sag which increases the likelihood of incomplete reset for Brake Unit and Brake Trolley.

8. zipSTOP BRAKE ASSEMBLY CONFIGURATION
8.1 General
The zipSTOP Brake assembly is designed to be utilized as part of a complete zip line braking system, and can be used for a wide range of zip line installations. The zipSTOP Brake assembly is suitable for use in both existing and new zip line installations.
Setup information contained within this manual relates only to the zipSTOP Brake assembly – The design, installation and set-up of other components comprising the complete braking system are the responsibility of the installer and/or operator.
COMPATIBILITY TESTING IS THE RESPONSIBILITY OF THE INSTALLER OR OPERATOR
The zipSTOP Brake is designed to work with most pulleys and zip lines but may not work with all. Compatibility is to be determined by the installer or operator based on experience and unmanned testing.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zipSTOP Brake assembly are estimates only and may differ from actual braking distances achieved on individual zip lines.
As there are infinite possibilities regarding participant weights and arrival speeds, line slopes and environmental conditions, a safe and functional installation can only be achieved after careful consideration and unmanned testing of all factors in advance of the zipSTOP installation.
The zipSTOP Brake is required to use both primary and emergency arrest devices functioning together to arrest the motion of passengers. The EAD must engage with no input from the passenger upon failure of the primary arrest device, and all required Confirmation and Warranty registration forms must be filled out and returned; failure to do so may void your warranty (see Sections “Emergency Arrest Device (EAD) Confirmation” and “Warranty Registration Form” respectively).
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.
8.2 Setup Variables, ZS125-08/ZSIR150-20A
A number of variables will influence the final braking distance and level of rider comfort, these include:
Rider arrival speed
Rider weight
Redirection Line Ratio (Only a 1:1 Applies with the ZSIR150-20A)
Zip line slope in the landing area
System friction
Environmental conditions (wind, rain, temperature)
Rider trolley used www.headrushtech.com | +1-720-565-6885
8.3 Rider Arrival Speed
Rider arrival speed is unique to each zip line installation and is a factor of line slope, zip line length, rider weight, rider descent position, wind and friction. It is necessary to know the acceptable minimum and maximum rider velocities prior to configuring the zipSTOP.
8.4 Rider Weight
Suitable rider weight ranges will need to be determined by individual zip line operators. The zipSTOP Brake unit will accommodate riders between 15 and 150 kg (33 and 330 lbs). It is necessary to know the acceptable rider weight range before configuring the zipSTOP.
8.5 Redirection Line Ratio
The Redirection Ratio is the most influential factor in the braking characteristics of the zipSTOP. The Redirection Ratio is the ratio between the Brake Trolley travel and the zipSTOP Braking Line extension.
The Redirection Ratio is achieved by passing the Redirection Line around a series of pulleys. This alters the ratio of Brake Trolley travel to Braking Line extension, allowing the installer to tailor the braking distances and deceleration rates, accommodating a wide range of arrival speeds and rider weights.
ZSIR150-20A - THIS PRODUCT CAN ONLY BE USED WITH 1:1 REDIRECTION SETUPS
The zipSTOP IR (ZSIR150-20A) is NOT compatible with external redirection setups in any way. Installing a redirection setup with the zipSTOP IR can create a very dangerous set of braking conditions that could result in abnormally abrupt late braking.
Various Redirection Ratios are possible:
1:1 Ratio
MUST be used for model ZSIR150-20A
Can be used for model ZS125-08
2:1 Ratio
Can be used for model ZS125-08 only
CANNOT be used for model ZSIR150-20A
3:1 and higher ratios – contact your zipSTOP Distributor, model ZS125-08 only
The recommended configuration orients all elements (zipSTOP Brake Unit, Redirection Pulleys, Brake Trolley) in the vertical plane.
When higher Redirection Ratios (3:1 and higher) are employed (for model ZS125-08 only), retraction force is reduced and a manual reset of the Brake Trolley will be necessary.
ALWAYS USE THE SPECIFIED REDIRECTION LINE
Failure to utilize a Redirection Line of specified strength and quality can compromise zipSTOP brake operation, resulting in equipment damage, serious injury or death.

Overhead Cable – 1:1 Redirection Ratio
The 1:1 Redirection Ratio directly connects the zipSTOP Brake Unit to the zipSTOP Brake Trolley via a single
Type I Redirection Pulley. For every unit of Brake Trolley travel, the Braking Line extends an equal distance.
Characteristics of the 1:1 ratio are:
Suitable for low speeds
Strongest braking force
Short braking distances
Higher rate of rider deceleration
Maximum rider approach speed of 36 km/h (22 mph) – model ZS125-08
Maximum rider approach speed of 60 km/h (37 mph) – model ZSIR150-20A
In the case of the model ZS125-08: A 1:1 Redirection Ratio is used for zip line installations where low arrival speeds are common. Although suitable for speeds up to 36 km/h (22 mph), typically a 1:1 ratio would be employed when approach speeds are less than 20 km/h (12 mph).

*EAD not shown but it is mandated*
Overhead Cable – 2:1 Redirection Ratio
The 2:1 Redirection Ratio connects the zipSTOP Brake Unit to the zipSTOP Brake Trolley via both Type I and Type
II pulleys. With a 2:1 ratio the Brake Trolley travels twice the distance that the zipSTOP Braking Line extends.
Characteristics of the 2:1 ratio are:
Suitable for medium to high speeds
Optimal combination of stopping distance, braking force and reliability in reset
Optimum rider comfort
Longer braking distances than a 1:1 setup
Overhead support line (redirection point) recommended
Maximum approach speed of 60 km/h (36 mph)
A 2:1 Ratio is used on zip line installations where medium to high approach speeds are common but a soft stop for the rider is desired. Although suitable for approach speeds up to 60 km/h (36 mph), typically a 2:1 ratio is employed when approach speeds are less than 40 km/h (24 mph).
A 2:1 Ratio is specifically PROHIBITED in any installation of the ZSIR150-20A. Utilizing an external redirection will lead to potentially dangerous and harmful braking dynamics.
ZSIR150-20A - THIS PRODUCT CAN ONLY BE USED WITH 1:1 REDIRECTION SETUPS
The zipSTOP IR (ZSIR150-20A) is NOT compatible with external redirection setups in any way. Installing a redirection setup with the zipSTOP IR can create a very dangerous set of braking conditions that could result in abnormally abrupt late braking.

8.6 Possible Configurations (Informative Only)
8.6.1 3:1 RATIO
3:1 installation formats are a unique situation and the following information should be used to develop an appropriate site plan.
The 3:1 ratio connects the zipSTOP unit to the braking trolley via redirection pulleys and supplementary line.
With a 3:1 ratio the braking trolley travels three meters for every meter of zipSTOP line. This will result in a longer stopping distance for the rider.
Characteristics of 3:1 ratio setup are:
Max. Approach Speed = 72 km/h.
Suitable for high arrival speed.
Softer stopping force from higher speeds
Longer stopping distances
More complex set-up.
A 3:1 ratio is commonly used on zip lines with high arrival speeds and when a longer braking distance is available. The 3:1 ratio is suitable for approach speeds up to 72 km/h (45 mph) allowing a softer stop after thrilling high speed runs.

8.6.2 OTHER CONFIGURATIONS
The zipSTOP Brake assembly may be used with other zip line configurations and higher rider velocities. Configurations shown are based on a single line zip line. Dual zip lines and side-by-side configurations may also be accommodated. Please contact your zipSTOP Distributor for information on alternate set-ups.
When higher Redirection Ratios (3:1 and higher) are employed (for model ZS125-08 only), retraction force is reduced and a manual reset of the Brake Trolley will be necessary.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.
Some examples of alternative configurations are shown below:
Beam Mounted Pulley - 2:1 Redirection Ratio
Offset Redirection Pulley – 1:1 Redirection Ratio
NOTE: Offset redirection pulleys should only be used with highly tensioned zip lines. Slack zip lines may cause binding and excessive wear on the brake trolley.
8.7 Zip Line Slope
Three zip line configurations at the end of the line are possible: flat line, positive line slope and a negative line slope. The slope of the line will influence the braking distances as well as allowing the rider to roll slowly up or down the line once decelerated. www.headrushtech.com | +1-720-565-6885
27
8.7.1 POSITIVE SLOPE LINE
This is the ideal configuration when designing a zip line incorporating the zipSTOP Zip Line Brake. The positive line slope configuration equalizes the braking distance between heavy and light riders, therefore minimizing the length needed for the arrival platform.

8.11 zipSTOP Braking Distance Charts
Charts for calculating braking distances are located at the back of this manual. These charts are to be used in conjunction with the zipSTOP configuration worksheet to optimize the zipSTOP installation. Ensure that you are using the correct chart for your zipSTOP model.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zip-
STOP Brake assembly are estimates only and may differ from actual braking distances achieved on individual zip lines. Exceeding maximum recommended line speed can cause injury to participants and damage equipment.
8.12 Configuration Notes
1. BDMIN LINE: BDmin line indicates the rate of deceleration that may be considered uncomfortable and result in severe rider swing up when stopping. It is not recommended to operate the zipSTOP with combinations of rider weights and arrival speeds that fall below the BDmin line. Operating below the
BDmin line runs the risk of rider swinging up and contacting the zip cable.
www.headrushtech.com | +1-720-565-6885
31
2. LINE EXTENSION (LEX) – Line extension is the distance the Braking Line extends out of the zipSTOP brake Unit. If LEX is greater than 12.0m then reduce maximum permissible approach speed (ASmax), permissible rider weight (RWmax) or increase Redirection Ratio (RR). Exceeding 12m runs the risk of an abrupt stop when the webbing reaches its termination as well as damage to the zipSTOP, webbing and other equipment.
3. BUFFER ZONE (BZ) – Buffer zone is the area after the Arrest Zone in which riders are safe from impacting the terminal end or any other object in the event they overshoot the landing zone. The buffer zone must include the maximum distance required for the EAD to arrest a wayward rider.

9. zipSTOP BRAKE ASSEMBLY INSTALLATION
9.1 General
Simply put, the zipSTOP Brake is designed to be mounted to a primary anchor point to slow the decent of riders on a zip line. The primary anchor point is exactly what it sounds like; it is the main attachment point for the brake. The secondary anchor point is the support point for the redirection lines and pulleys.
The zipSTOP Brake Unit is installed at the end of the zip line, usually on or adjacent to the terminal end. A
Secondary Anchor Point is normally required upstream of the landing area to provide support for the Redirection Line pulleys AND forces associated with braking. Alternately a full-length secondary cable of sufficient capacity can be installed to provide support for the Redirection Line and associated pulleys.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.
9.2 Safety Precautions
ALWAYS INSTALL AN EMERGENCY ARREST DEVICE (EAD)
An independent arrest device is required to safely stop riders in the event of operator error or third party equipment failure.
PROPER DESIGN AND TESTING OF THE COMPLETE BRAKING SYSTEM IS ALWAYS REQUIRED
The complete brake system for zip Lines consists of all brakes employed, including primary brake and EAD.
All braking installations that include the zipSTOP as a component of the braking system must be designed, tested and operated according to this Installation, Operation and Maintenance Manual and proper industry and engineering practices. Failure to do so may result in serious injury or death to participants.
Exceeding maximum recommended line speed can cause injury to participants and damage equipment.
FAILURE TO CORRECTLY INSTALL OR MAINTAIN A ZIPSTOP BRAKE ASSEMBLY MAY RESULT IN
SERIOUS INJURY OR DEATH TO PARTICIPANTS.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zipSTOP Brake assembly are estimates only and may differ from actual braking distances achieved on individual zip lines.
AVOID CONTACT BETWEEN RIDER AND RIDER TROLLEY AND/OR BRAKE TROLLEY
Serious injury may result if rider contacts the rider trolley or Brake Trolley during the braking phase. Always design zipSTOP Brake assembly installation to ensure rider cannot make contact with, or have any part of their body caught between, the rider trolley and Brake Trolley.
www.headrushtech.com | +1-720-565-6885
ENSURE ALL CABLES, ATTACHMENT LINES AND PULLEYS ARE CORRECTLY ATTACHED AND
MAINTAINED TO PREVENT TANGLING, SNAGGING, BINDING AND ABRASION.
Ensure that the Redirection Line is routed cleanly and in line through the pulley system, to prevent contact with any surface other than the pulley sheaves.
ALL STRUCTURES, SUPPORTS AND ANCHORS MUST BE EVALUATED AND DESIGNED AC-
CORDING TO PROPER INDUSTRY AND ENGINEERING PRACTICES. QUESTIONS ABOUT
STRUCTURES, SUPPORTS AND ANCHORS SHOULD BE REFERRED TO YOUR ZIP LINE’S ENGI-
NEER.
The act of decelerating a rider at the termination of a zip line can generate extreme loads.
9.3 Primary Anchor Point
The Primary Anchor Point provides support for the zipSTOP Brake Unit. The anchor point and associated fittings must be of sufficient strength and form to provide a secure mount and to support all applied loads sustained during zip line operation.
Loads specified are for the zipSTOP Brake assembly installation only and do not allow for any additional equipment or other loadings applied to the primary mount or additional units attached to the same line.
The zipSTOP Brake Unit is attached to the Primary Anchor Point using three M12 or ½” fixing bolts.
Loads at Primary Anchor Point
In-line with Braking Line
Right angles to Braking Line
6.0 kN
Negligible
The loads specified are applied loads for the zipSTOP Brake Unit only. These loads DO
NOT allow for additional loads applied by other equipment or structures. Ensure sufficient factor of safety is applied in the structural design of all zip line installations.
9.4 Secondary Anchor Point
The Secondary Anchor Point provides support for redirection pulleys and hardware used in the Redirection
Line setup. The design of the Secondary Anchor Point must be sufficient to withstand all applied loads experienced during zip line operation.
Loads specified are for zipSTOP Brake assembly installation only and do not allow for any additional equipment or other loadings applied to the secondary mount including redirection lines for additional units.
Loads at Secondary Anchor Point

9.4.1 POSITION OF THE SECONDARY ANCHOR POINT
The Secondary Anchor Point is located in line with the start of the Arrest Zone (Brake Trolley Reset Point). It provides the location for the attachment of the Type I Pulley above the zip line and also attachment of any secondary or support lines that may be required.
Ensure the Secondary Anchor Point and any supporting structure are at least one meter above the zip line and at a sufficient distance from the zip line to prevent contact with the rider, redirection line, and other equipment.
Always install pulleys so as to prevent any tangling, snagging or binding with other lines or objects. Ensure that the Redirection Line is routed cleanly and in line through the pulley system to prevent contact with any surface other than the pulley sheaves.
9.5 Redirection and Support Lines
All lines must be sewn, spliced, or properly terminated.
Only use an approved termination method for all rope connections. Using a Double Figure 8 knot to terminate a Redirection Line is not recommended by Head Rush Technologies for lines with Spectra or Dyneema sheaths. Spectra and Dyneema have low coefficients of friction which can result in knots becoming untied. A
Double Figure 8 knot also reduces line strength by 20-25% when tied properly and can reduce line strength by more if tied incorrectly.
All Redirection Lines and support lines are to be manufactured to specified strength and are to be suitable for all-season outdoor. When installing redirection and support lines, use route lines to ensure that:
All lines are installed in such a way as to prevent loose or sagging lines, tangling, snagging or binding with other zip line components.
Lines are to be routed to eliminate abrasion and undue wear.
All lines are laid out so as not to present a tripping or injury hazard to zip line staff or riders.

9.6 Fitting zipSTOP Brake Unit
The zipSTOP Brake Unit may be mounted horizontally or vertically. The mounting bracket is designed for use with a flat or curved surface. Curved surfaces must have a minimum 150 mm (6“) diameter.
ONLY INSTALL THE ZIPSTOP BRAKE UNIT ORIENTED DIRECTLY INLINE WITH THE TYPE 1 PULLEY
The Braking Line feeds straight out of the device, without twist, and centered within the Nozzle. Accelerated Braking Line wear may occur if the line bears onto the Nozzle edge.
DO NOT REUSE SELF-LOCKING NUTS
Always use new nuts, as reuse of self-locking nuts may compromise connection integrity. This type of nut is used on the Brake Trolleys.
Fit the zipSTOP Brake Unit as follows:
INSTALLATION NOTES
Always orient the zipSTOP Brake Unit directly in line with Type I Pulley.
Always use through bolts with large washers and self locking nuts.
It is recommended that double helix spring washers are located under mounting nuts to allow for movement in primary mount point when used on a wooden structure or use split ring washer or comparable with a rigid structure to reduce risk of loosening due to vibration
Always mount the zipSTOP Brake Unit a sufficient distance from the zip line so that Redirection Lines and pulleys do not interfere with rider.
Once installation is complete ensure the zipSTOP Braking Line is not twisted and feeds linearly through the Nozzle.

10. OPERATION OF zipSTOP
10.1 Safety Precautions
ALWAYS CORRECTLY INSTALL, MAINTAIN AND OPERATE THE ZIPSTOP BRAKE ASSEMBLY
Failure to do so may result in serious injury or death to participants.
ALWAYS OPERATE A ZIPSTOP BRAKE ASSEMBLY WITH AN EMERGENCY ARREST DEVICE (EAD)
ACTIVE
Failure to do so may result in serious injury or death to participants
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zipSTOP Brake Assembly are estimates only and may differ from actual braking distances achieved on individual zip lines.
ALWAYS OPERATE WITH RIDER FACING FORWARD UPON ARRIVAL INTO THE ARREST ZONE
Serious injury due to upswing may result if rider is not in the forward-facing position. Arrivals without orientation control should be verified such that minimum and maximum rider weight patrons cannot come into contact with the line, brake trolley, or other equipment during deceleration when arriving backwards uncontrolled.
ALWAYS USE THE CORRECT ZIPSTOP BRAKE TROLLEY
Failure to use the correct trolley may compromise system operation and result in serious injury to rider.
AVOID CONTACT BETWEEN RIDER AND RIDER TROLLEY AND/OR BRAKE TROLLEY
Serious injury may result if rider is in contact with trolley when it impacts the Brake Trolley. Always design the zipSTOP installation so rider cannot be in contact with, or have any part of their body caught between, the rider trolley and Brake Trolley.
ENSURE ALL CABLES, ATTACHMENT LINES AND PULLEYS ARE CORRECTLY ATTACHED AND
MAINTAINED
Ensure that the Redirection Line is routed cleanly and in line through the pulley setup, to prevent contact with any surface other than the pulley sheaves. Any tangling, snagging, binding and abrasion may compromise system operation and result in serious injury to rider.
AVOID MAXIMUM LINE EXTENSION OF BRAKING LINE
Repeated extension of braking line to maximum Line Extension (LEX as defined in this manual) will cause premature wear and void warranty coverage of the retraction spring.
www.headrushtech.com | +1-720-565-6885
49
50
E
NSURE BRAKE TROLLEY ALWAYS RESETS TO THE START OF THE ARREST ZONE
Failure to reset the Brake Trolley will compromise braking performance and may result in serious injury or death and/or equipment damage.
THE BRAKE TROLLEY CANNOT BE TIED BACK IN ANY WAY, BY ANY METHOD, OR BY ANY
ACTION DURING OPERATIONAL HOURS
Any restriction of the brake trolley during operational hours may result in serious injury or death, or equipment damage.
10.2 zipSTOP Operation as a Primary Brake
The zipSTOP is designed to provide consistent and reliable braking to a zip line ride. Brake performance relies on operators using the correct equipment and operating the zip line in accordance with the instructions contained within this manual.
THE ZIPSTOP BRAKE MUST:
Function without permanent deformation or failure of associated equipment.
Arrest the motion of the rider regardless of rider orientation.
Not inhibit rider retrieval in the event that arrest occurs before the landing area is reached.
10.3 zipSTOP Operation as an EAD
When used as an EAD the zipSTOP brake must be installed to engage upon failure of the primary brake, with no action from the rider, in order to prevent serious injury or death to participants. The EAD will be installed as either completely separate from the primary brake or as an integrated backup feature.
AN EAD MUST BE USED WHEN:
The rider arrives at the landing area at a speed over 6 mph (10 km/h).
The rider encounters unintended harmful contact with terrain, objects, or people in the landing area.
10.4 Landing Areas
Landing areas are integral to the proper function of zip line braking, and shall:
Provide sufficient space for brake operation and dismount procedures.
Provide protection from or limit unintended contact with zip lines, people, and other components.
Be free from hazards that require rider action to avoid. Objects in the landing area that have potential to harm riders shall be covered with shock absorbing material.
www.headrushtech.com | +1-720-565-6885
10.5 Operation During Extreme Weather Conditions
zipSTOP equipment has been designed for use in a wide range of temperature and weather conditions. Extreme heat and cold weather will not alter the performance of the equipment, nor will operations in wet conditions, however, the following should be observed:
WET LINE WARNING
When the line is wet it may slightly alter the performance of the zipSTOP device. This may result in increased braking distances and/or increased braking forces. Care must be taken when operating in wet conditions.
When operating in freezing temperatures, it is of critical importance that all lines are kept dry. If lines become wet and subsequently freeze, normal retraction/extension may become limited, which may result in increased or dangerous rates of deceleration or an increased likelihood of reset failure. If lines become wet during freezing temperatures, or when normal extension/retraction becomes limited, cease all operation immediately.
FULLY EXTEND BRAKING LINE TO ALLOW DRYING
When operating the zipSTOP in wet conditions, the Braking Line must be fully extended and allowed to completely dry in order to get the longest life from the lines.
INSPECT LINE FREQUENTLY IN EXTREME WEATHER CONDITIONS
When operating in extreme wind, weather, temperature, humid conditions, UV light exposure, or near salt/ marine environments, increase line inspection frequency and replacement frequency. The line must be replaced if any signs of deterioration are evident.
10.6 Resetting the Brake
CHECK BRAKE TROLLEY HAS CORRECTLY RESET AFTER EVERY RUN
The Unit is designed to stop retracting if there are any internal issues and in the case of many overload situations. Any indication of a failure to reset should be checked and if found to be may be cause for immediate removal from service. Please contact your local service center for repair should the unit fail to reset consistently.
BRAKE RESET FAILURE
Failure to reset the Brake Trolley will result in insufficient braking and may result in serious injury or death of rider.
The zipSTOP Brake Trolley should automatically return to the start of the Arrest Zone (Reset Position) once the rider trolley is removed. With the Brake Trolley positioned in the Reset Position, the zipSTOP Braking Line will be fully retracted.
www.headrushtech.com | +1-720-565-6885
51
52
zipSTOP Brake Unit fully retracted
An arrival platform attendant should always check for the correct reset position of the Brake Trolley and the zipSTOP Braking Line at the completion of each run, prior to a subsequent run. Redirection lines should be visually checked after brake trolley reset to ensure they are running free and clear, have not become tangled, etc.
If the Brake Trolley fails to reset, check that the zipSTOP Brake Unit is operating correctly and the Redirection
Line is not tangled, snagging, or binding.
10.7 Operational Retraction Spring Cycle Limit
Operational cycle limits for the zipSTOP are based upon fatigue limits of the internal retraction spring. Exceeding the life of the retraction spring will prevent the zipSTOP from automatically resetting but will not affect the braking performance of the device. However, if the brake trolley does not reset, the rider will not be able to engage the zipSTOP, resulting in no braking for the rider. There is no cycle limit for the core braking components of the zipSTOP. Do not continue to operate the zipSTOP if the brake trolley fails to consistently reset.
Operators must ensure the brake trolley resets before every zip run.
In order to maximize the life of the retraction spring, avoid extending the braking webbing (LEX) longer than necessary. Repeated extensions of the webbing near the maximum line extension (12m / 39ft Model ZS125-08,
20m / 65ft Model ZSIR150-20A) will prematurely wear out the retraction spring and may void the warranty.
Extremely high throughput facilities may be required to send their devices in for recertification more frequently than the annual requirement. Recertification includes replacement of this component and is a required and necessary service for the zipSTOP.
Since webbing extension varies greatly for each installation and rider weight and speed, it is difficult to determine a cycle limit for the retraction spring. However the retraction spring in Model ZS125-08 should be capable of 10,000 cycles for a webbing extension of approximately 35 ft (11 m). The retraction spring for Model
ZSIR150-20A should be capable of 50,000 cycles at approximately 55 ft (17 m). Retraction Spring cycle limits are approximations only and may decrease for extensions greater than that listed above. Facilities expecting drastically higher throughput than this should expect an increased recertification period and may contact
Head Rush Technologies for more information.

11. TROUBLESHOOTING
Use this information to assist in troubleshooting problems that might occur during operation. If a problem cannot be resolved, remove components from service and contact your Head Rush Technologies Service Center.
SYMPTOM POTENTIAL CAUSE RESOLUTION
Pivot height is too high
In most cases your redirection point has been established. Hopefully this distance correlates to the performance of the brake you wanted to achieve. If the braking performance is adequate and consistent consider moving your redirection point further away and adapting to the longer braking distance.
Braking distance is too long
Your speeds are higher than expected
If you’re still within the safety window of your EAD and other equipment consider using the higher speed and adjusting your redirection point to allow for the longer braking distance. If speeds have become unsafe for your equipment or your EAD consider adjusting your line tension to slow arrival speed.
You have a lot of positive slope in the line
This is actually an optimal condition but may not be covered by the basic table. More positive slope means more consistent arrival for your riders regardless of weight and increased throughput on your lines. If rider speed is within safety limits consider leaving this slope and adjusting braking distance to allow for it. If your installation cannot accommodate the increased braking distance consider lowering the tension on your lines.
NOTE: REDUCING LINE TENSION MAY NEGATIVELY AFFECT THROUGH-
PUT AND MAY INCREASE THE NEED FOR RIDER RETRIEVAL. USE THIS
CORRECTION ONLY AS A LAST RESORT.
Pivot height is too short or you are using the zipSTOP Pivot
Mount
When appropriate, some installations may choose to use the zipSTOP
Pivot Mount which may result in shortened braking distances and higher braking loads. Alternatively, a pivot height which is too high may also result in shortened braking distances and higher braking loads. In either case, an increased pivot height or change to a ZSIR or 2:1 redirection ratio will serve to increase braking distance and reduce loads.
Braking distance is too short
Your speeds are lower than expected
If you’re installation is still well within the safety limits of your equipment and EAD consider adding tension to your line or additional slope. Be aware that additional tension will place additional load on your rider cable and could take it out of operational safety limits. Alternatively, check friction in your rider trolley.
NOTE: ONLY INCREASE LINE TENSION FOLLOWING DIALOGUE WITH A
PROFESSIONAL ENGINEER OR ZIP LINE INSTALLER.
Trolley camming interference
Interference between safety carabiners or the bottom or sides of the trolley on impact can have a radically increased effect on braking with the additional drag. Not only will this interference radically degrade the performance/lifespan of your components it makes braking distance very hard to control. The camming will not be consistent rider to rider based on weight and speed of arrival. Recommend changing trolleys or introducing a camming restrictor.
www.headrushtech.com | +1-720-565-6885
53
54
SYMPTOM POTENTIAL CAUSE RESOLUTION
Drag in the system
Check your pulleys to ensure that the sheaves are operating smoothly and without drag. Also ensure that all your angles to and from all redirection pulleys are straight and that the brake trolley angle is parallel to its immediate redirection point. Make sure that the zipSTOP webbing is being extracted straight out of the unit. Correct as necessary. It may be necessary to customize the mounting location of the zipSTOP, traveler, support and/ or redirection pulleys to ensure straight webbing extraction during braking.
Alternatively, make sure crosswinds are not inducing large lateral angles in your redirection line.
A lot of negative slope in the line
While gravity braking is a tried and true method of controlling arrival speed it definitely will shorten the distance of braking after impact. In installations with a lot of “belly” in the line this braking distance may be acceptable or outside design parameters. Whenever possible consider removing slack in the line and adjusting the zipSTOP and rigging for higher arrival speeds
(remember the zipSTOP can handle extreme speeds with redirections up to 3:1). If arrival speed and recovery methodology is acceptable the redirection point can be moved in to facilitate the shorter braking/speed.
Braking distance is too short
(continued)
Strong headwinds
If the headwind is anomalous consider adjusting recovery methodology.
If headwinds are consistent and year round consider increasing the speed of the line through tension if safety limits allow. Alternatively, adjust the redirection point closer to the zipSTOP to allow for the shorter braking distance IF and ONLY IF head winds are consistent. WARNING: Artificially shortening the braking distance can result in EAD impact on days with little or no head wind.
High friction in a cable interface
This is related specifically to friction in the trolley or brake trolley mechanism. Slack lines can allow the brake trolley and or rider trolley to impact the zip line in non-standard locations or side surfaces. On jacketed cable this can cause severe drag and wear impact on the zip line. In non-jacketed zip lines this still can add significant friction and wear. Attempt to keep the loading of the slack cable and break line in the vertical plane during impact whenever possible to eliminate side loading of devices. In installations where side loading is inevitable consider a 4 sheave brake trolley or alternative rider trolley.
Incorrect angles
Ropes induce friction over tight and multiple angles. The more these ropes are subjected to extreme angles the more friction will be experienced in the redirection setup. Occasionally, these angles and additional loads are by design in which case the redirection point can be shortened and the setup compensated for the shorter distance braking. Other times this indicates a redirection point that needs adjustment for angle and tension.
www.headrushtech.com | +1-720-565-6885
SYMPTOM
Braking distance is too short
(continued)
POTENTIAL CAUSE RESOLUTION
Auxiliary retraction device interference
Auxiliary Retraction Devices are not recommended. Occasionally extreme
2:1 installations or 3:1 or greater installations will have alternative clothesline type reels or weight assisted retraction devices to help facilitate automatic reset. These devices RADICALLY alter the brake application forces and add to the brake resistance of the zipSTOP. If counter weights are being employed consider lowering the mass and if clothes line type reel to reel assemblies are used ensure the friction is as low as possible and the inertial weight of the components is as low as possible. ALWAYS: Make sure these components are well clear of the zipSTOP and its redirection lines and incapable of interfering by binding or cutting the redirection lines.
Braking is too abrupt
Wrong redirection or unit for speed
If your speed is outside the limits for the device or redirection, braking will be much more abrupt for your riders. Consider increasing external redirection ratio or using the zipSTOP Internal Redirection (IR) unit for speeds up to 60km/h (37mph)
NOTE: IF YOU USE Redirection RATIONS OF GREATER THAN 2:1, YOU
WILL BE REQUIRED TO RE-SET THE BRAKING DEVICE AFTER EVERY DE-
SCENT.
Trolley camming interference
Interference between safety carabiners or the bottom or sides of the trolley on impact can have a radically increased effect on braking with the additional drag. Not only will this interference radically degrade the performance/lifespan of your components it makes braking distance very hard to control. The camming will not be consistent rider to rider based on weight and speed of arrival. Recommend changing trolleys or introducing a camming restrictor.
Webbing extended at impact
Any webbing extended from the zipSTOP at the time of impact will increase the speed at which the brake applies full force. In many instances this can and will lead to abrupt and undesirable braking. Unless by design, and thoroughly tested at max and minimum rider weights at max speed, the webbing should never be extended prior to brake engagement. SLACK LINE: In slack line installations it should be noted that the distance between the rider line and redirection point dynamically grows as the rider approaches the impact point due to cable deflection and this results in increased brake force application. In most instances this will be within operational limits as the webbing will have most of its pre-extraction on only the heaviest riders. Adjust your redirection point and length of redirection line as necessary to ensure full reset of the zipSTOP webbing.

SYMPTOM
Braking is too abrupt
POTENTIAL CAUSE RESOLUTION
Pulley friction and system drag
Check your pulleys to ensure that the sheaves are rotating smoothly and without drag. Also ensure that all your angles to and from all redirection pulleys are straight and that the brake trolley angle is parallel to its immediate redirection point. Make sure that the zipSTOP webbing is being extracted straight out of the unit. Correct as necessary. Use a traveler assembly to support the weight of the webbing and redirection line. It may be necessary to customize the mounting location of the zipSTOP to ensure straight webbing extraction during braking. Alternatively, make sure crosswinds are not inducing large lateral angles in your redirection line.
Heavy redirection line
Whenever possible use the smallest and lightest redirection line that provides at least 13kN in operational strength. Utilizing Dyneema ® or Technora
® materials and composites can help alleviate the mass and inertia associated with the redirection line and help reset. Be aware that these products and any other advanced composites are usually accompanied by special and specific maintenance and inspection procedure and termination methods ensure their continued safe use. Always make sure your EAD is up to the capacity of the line before reducing the size of your redirection line.
Lack of a traveler assembly and/or support pulleys
Refer to your operator’s manual and above sections for figures and an understanding of a traveler mechanism. A traveler is highly recommended at the zipSTOP webbing to redirection line interface to ensure smooth operation. In installations where an overhead line has not been implemented consider adding at least a short line to accommodate a traveler mechanism.
The retraction force on the line is at its lowest point as the webbing nears full retraction. Eliminating any resistance at the webbing nozzle by controlling the angle of the webbing will help ensure full reset every time. The zipSTOP IR unit or any zipSTOP in 2:1 or 3:1 configuration will require a traveler and guide line for the webbing in all installations.
Redirection cable sagging
Heavy redirection line
Whenever possible use the smallest and lightest redirection line that provides at least 13kN in operational strength. Utilizing Dyneema ® or Technora
® materials and composites can help alleviate the mass and inertia associated with the redirection line and help reset. Be aware that these products and any other advanced composites are usually accompanied by special and specific maintenance and inspection procedure and termination methods ensure their continued safe use. Always make sure your EAD is up to the capacity of the line before reducing the size of your redirection line.
Support pulleys not used or spaced too far apart
Use properly spaced support pulleys to support the weight of the redirection line. Support pulleys may be mounted to the overhead line to support the weight of the redirection line and/or to prevent the line from becoming entangled. You must ensure the location of the support pulleys will not interfere with the extension of the webbing/traveler assembly. This is especially important if using heavy redirection line or when operating in high wind. Fixed support pulleys are typically not used with ZS IR.
www.headrushtech.com | +1-720-565-6885
SYMPTOM POTENTIAL CAUSE RESOLUTION
Redirection cable sagging
(continued)
High wind conditions
If the prevailing wind is particularly a crosswind, the redirection lines can be pulled way out of alignment with the redirection points increasing friction and drag in the system. Where possible, wind should be shielded or blocked or lines shortened to minimize side wind loading on the redirection assembly. Testing should ensure safe operation during high crosswinds or low crosswinds. In some cases extremely high crosswinds can indicate shut down or operational safety limits that need to be a part of your operational safety parameters. Using a small diameter redirection rope, such as Head
Rush Technologies’ 6mm diameter Gorilla Rope, will greatly reduce the amount of wind loading on the redirection line.
System friction
Substandard pulleys, unnecessary redirection points, multiple rope angle changes, and uncharacteristically difficult redirection angles will add friction and inertia to the system in addition to weight of the system. Additional weight and drag will result in sub optimal retraction and line sagging. Eliminate unnecessary points and eliminate tight angles and high friction devices where possible.

13. BRAKING DISTANCE CHARTS
CAUTION
Always complete unmanned testing to determine actual braking distances and allowable swing up of rider at given weight and arrival speed. Riders stopping too abruptly will swing up and potentially contact the cable. Do not operate the zipSTOP with an excessive amount of rider swing up.
Calculated braking distances shown on charts are for guidance use only. Actual braking distances will vary due to site conditions, weather conditions and final configuration of zip line set-up.
Braking distances shown on charts refer to installations where zipSTOP Braking Line is fully retracted when
Brake Trolley is positioned at the start of the Arrest Zone (Reset Position). If zipSTOP Braking Line is not fully retracted when Brake Trolley is reset, then actual braking distance will be different to that shown on the chart.
Braking distances that fall below the ‘BDmin’ line will result in high level of braking force being felt by the rider, and may cause severe swinging up of the rider’s body during braking.
Distances listed are only a starting point and may need to be adjusted based on individual installations.
THE BRAKING LINE MUST BE FULLY RETRACTED INTO THE ZIPSTOP AT THE POINT OF BRAKE
INITIATION
Serious injury, death, or damage to equipment can occur if Brake initiation occurs without a fully retracted
Braking Line.
SAFE OPERATION IS CONTINGENT UPON OPERATING WITHIN THE PERFORMANCE CHARTS
BELOW
Operating outside of these parameters may result in equipment damage or in injury or death of the rider.

15.3.4 PERFORMANCE
Use zipSTOP Braking Distance charts in the zipSTOP Operator’s Manual and the diagram below to determine braking distances and performance. Due to the direct connection between the unit and the brake trolley in the zipSTOP Pivot Mount setup, the braking distances may be shorter than in the zipSTOP Braking Distance charts.
Use the zipSTOP Braking Distance charts only as a starting point for tuning performance and braking distance as external and installation factors can change performance.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup configuration only. Mandated EAD may or may not be shown.

perature and weather conditions. If a component is found to be damaged or worn during inspection, replacement parts are available from Head Rush Technologies and Authorized Service Centers.
15.3.6 INSPECTION PROCEDURES
Weekly Inspection: Prior to installation and operation of the zipSTOP Pivot Mount, it should be fully inspected according to the procedure below. This inspection should also be performed weekly with regular zipSTOP Zip
Line Brake Unit Case inspection. Both inspections may take place simultaneously but there are independent inspection elements for both products mandating both procedures be followed.
Inspection Procedures:
1. Inspect each side plate extensively for damage, cracks, corrosion, or signs of fatigue.
2. Inspect the quick link, upper spacer, and upper bolt for signs of wear and corrosion. Ensure the quick link gate is tightly closed.
3. Inspect each O-ring for signs of cracking, wear, and degradation.
4. Check the center plate spacers and corresponding bolts for signs of corrosion or degradation.
5. Ensure the cotter pins are seated firmly, the protruding end is split, and each tail bent outward to at least 90 degrees.
The zipSTOP Pivot Mount should be removed from service and the component or entire assembly replaced if any component demonstrates signs of damage, cracking, yielding, corrosion, or significant wear or abrasion.
FAILURE TO CONDUCT WEEKLY INSPECTIONS AND/OR REPLACE COMPONENTS OF THE PIVOT
MOUNT WHEN SIGNS OF WEAR ARE PRESENT MAY RESULT IN SERIOUS INJURY OR DEATH OF A
PARTICIPANT
Any indication of the zipSTOP Pivot Mount or unit being out of specification mandates the immediate removal of the mount or device from service.
NOTE
Varying weather, use, humidity, and UV conditions can affect the expected service life of the zipSTOP Pivot
Mount, zipSTOP Zip Line Brake, and associated equipment significantly.
