September 19, 2005 6 STAGEMAKER® OP MAN 2005-0.doc ® R&M Materials Handling, Inc Springfield, Ohio USA STAGEMAKER® COMPACT Concert Hoist Operator’s Manual : 800-955-9967 www.rmhoist.com 4 4.1 September 2005 ELECTRIC CHAIN HOIST CONSTRUCTION General Hoist Construction Overhead hoists are defined in the ANSI / ASME standards as a machinery unit that is used for vertical lifting service involving material handling of freely suspended (unguided) loads. Overhead hoists are a basic and versatile piece of equipment used in manufacturing, warehousing, construction, and numerous other applications to aid workers in the handling and moving of loads. Overhead hoists are available in various types of configurations and constructions. Overhead hoist types are usually referred to using the terms that define a specific configuration and construction. The following are three areas that further define the hoist type. 4.2 Lifting Medium Lifting medium defines the type of component used to transmit and cause vertical motion of the hoist ® load hook, hoist body, or hoist load block. Chain is a lifting medium. STAGEMAKER COMPACT Concert Hoists uses welded link load chain. Welded Link Load Chain Welded link load chain consists of a series of interwoven formed and welded links. The links fit pockets of the hoist load sprocket that transmits motion to the load chain. The load sprocket may also be called load wheel, load sheave, pocket wheel, chain wheel, or lift wheel. Welded link load chain sizes are stated as the diameter of the wire used to form the link, i.e. 3.1mm, 4.8mm, 6.8mm, etc. Welded link load chain is designed and manufactured to specific dimension and material strength requirements for a specific hoist. Welded link load chain is not interchangeable between different manufacturers’ hoists; and is not interchangeable with welded link lifting chain used for other purposes such as chain slings and securing the load. Only original equipment welded link load chain, as supplied by R&M Materials Handling, Inc., ® shall be used on any STAGEMAKER COMPACT Concert Hoist. 4.3 Power for Operation Power for operation defines the type of power used to operate the hoisting motion. The electric chain hoist uses electrical power to run an electric motor that provides the motion for lifting and lowering the load. ON ELECTRIC POWERED HOISTS, HAZARDOUS VOLTAGES ARE PRESENT IN THE CONTROL BOX, OTHER ELECTRICAL COMPONENTS, AND CONNECTIONS BETWEEN THESE COMPONENTS. September 19, 2005 7 STAGEMAKER® OP MAN 2005-0.doc ® R&M Materials Handling, Inc Springfield, Ohio USA : 800-955-9967 www.rmhoist.com STAGEMAKER® COMPACT Concert Hoist Operator’s Manual September 2005 Electric Power The hoisting motion (lifting or lowering) of an electric powered hoist is initiated when the operator grasps and activates a control device. The control device has push buttons that energize, through a series of contractors and other electrical components, an electric motor. The electric motor transmits power through the hoist gearing to the hoist load chain sprocket. Thereby, lifting or lowering the hoist load hook. Lifting is accomplished by actuating the lifting control; and lowering is accomplished by activating the lowering control. The controls could be marked: LIFT/LOWER; UP/DOWN; RAISE/LOWER; or a combination of such markings. Hoist lifting and lowering controls are usually pushbuttons mounted in a pendant control enclosure suspended from the hoist, levers or switches mounted in a remote radio-control transmitter and/or a control console. Control consoles, pendant control enclosures, radio-control transmitters, or other control means could also be permanently mounted on the building structure depending on the application. The control device used to lift and lower hoist motion may also contain controls for other motions or functions. Such controls include: trolley travel, overhead crane travel, power on/off, emergency stop, motions associated with below-the-hook lifting devices, and other special functions associated with a specific application. Examples of such control markings may include, but are not limited to, EAST / WEST; RIGHT / LEFT; OPEN / CLOSE; START / STOP; etc. Suspension Types Suspension defines the type of mounting or method used to mount or suspend the hoist. Common suspension types include hook mounted and trolley mounted. Other types of suspension may be designed to meet specific application requirements. When the above various types of configurations or constructions are considered, some of the names used to refer to overhead hoists include: hook mounted electric chain hoists; lug mounted electric chain hoists; push trolley mounted electric chain hoists; motor driven trolley mounted chain hoists; etc. Hook Mounted Hook mounted hoists have a body hook on the hoist body that can be used to suspend the hoist from the clevis or suspension pin of a trolley; or a fixed suspension device, that will accept the hook, mounted on a beam or the structural framework of a building. Lug Mounted Lug mounted hoists have a lug mounting attached to the top of the hoist frame, or a lug mounting attached as an integral part of the hoist frame. Lug mounted hoists are available in all hoist types. Lug mountings are used to suspend the hoist from a trolley, or a fixed suspension device mounted on a beam or the structural framework by the use of suspension pin(s) or stud(s). Trolley Mounted Trolley mounted hoists are hook mounted or lug mounted hoists suspended from a trolley; or a hoist having an integral trolley as part of the hoist frame, that allows travel motion on the lower flange of a monorail beam, or the lower flange of the bridge beam of an overhead crane. Trolleys allow traverse motion of the hoist unit, and load being handled, by traveling: on the lower flange of a monorail beam; on the lower flange of a bridge beam of an overhead crane; or September 19, 2005 8 STAGEMAKER® OP MAN 2005-0.doc ® R&M Materials Handling, Inc Springfield, Ohio USA STAGEMAKER® COMPACT Concert Hoist Operator’s Manual : 800-955-9967 www.rmhoist.com September 2005 on top of the bridge beams of an overhead crane. Hoist trolleys are available in several types depending on the method used to obtain travel motion. Trolley types include: Plain (Push) Trolleys Plain type trolley motion is obtained by pulling or pushing the load or by some other means, such as the strain relief of a pendant control, suspended from the trolley or hoist. Plain type trolleys are recommended where trolley motion is infrequent or relatively short. Because of the force required to manually operate this type of trolley, it is recommended that the use of plain trolleys be limited to a maximum capacity load of 3 tons or 3000 kg, and that the elevation of the beam where the trolley is suspended be not more than 20 feet or 6 meters above the operating floor level. Hand Chain Operated (Hand Geared) Trolleys Hand geared trolley motion is achieved by grasping and pulling a continuous hand chain that is connected to the trolley. Hand chain consists of a series of interwoven formed welded or un-welded links according to the design specifications of the hand chain. The hand chain links fits pockets of the trolley hand chain wheel, or sprocket. As the operator pulls the hand chain, the hand chain wheel turns and transmits power through gearing to the trolley wheels. Pulling the hand chain in one direction will cause the trolley to travel in the opposite direction. Hand chain manually operated trolleys provide excellent load spotting ability. Electric Powered (Motorized) Trolleys Motorized trolley motion is achieved by activating a control device in the same manner as described under electric powered hoists. The control device used to lift and lower hoist motion may also contain controls for trolley travel. Recommendations for use of electric powered are based on frequency of operation, distance of travel, capacity of load, height of beam, and type or size of load being handled. 4.4 Directional Travel of Overhead Hoists Hoist motion is the vertical travel motion direction of the hoist load hook. The hoist operator should be familiar with the hoist (or crane) controls and understand what type of motion will occur when any one of the control devices is activated. The controls SHALL be marked, and all markings SHALL be legible. A routine inspection, required to be performed by the operator prior to the hoist being used each day, SHOULD include a check that all motions agree with control device markings. September 19, 2005 9 STAGEMAKER® OP MAN 2005-0.doc ® R&M Materials Handling, Inc Springfield, Ohio USA STAGEMAKER® COMPACT Concert Hoist : 800-955-9967 www.rmhoist.com Operator’s Manual September 2005 Overhead hoists have one axis of directional travel. This is: • THE HOISTING OR VERTICAL TRAVEL DIRECTION OF LOAD HOOK OR HOIST BODY When overhead hoists are trolley suspended, the trolley hoist unit has two axes of directional travel. These include: • THE HOISTING OR VERTICAL TRAVEL DIRECTION OF THE LOAD HOOK / BODY. • THE TRAVERSE TRAVEL DIRECTION OF THE TROLLEY (INCLUDING HOIST UNIT) When trolley suspended overhead hoists are used on an overhead crane, the crane, including the trolley hoist unit has three axes of directional travel. These include: • THE HOISTING OR VERTICAL TRAVEL DIRECTION OF THE LOAD HOOK • THE TRAVERSE TRAVEL DIRECTION OF THE TROLLEY (INCLUDING THE HOIST UNIT) • THE TRAVERSE TRAVEL DIRECTION OF THE BRIDGE (INCLUDING THE TROLLEY AND HOIST UNIT) Some hoists or cranes may have power-operated rotating hooks, power-operated below-the-hook lifting devices, or other power-operated accessories that result in additional axes of directional travel. If more than one hoist or trolley hoist unit is used on an overhead crane, each hoist or trolley hoist SHALL have an identification mark on it or its load block, and these markings SHALL also appear on the controllers used by the operator. For example, if a crane has two trolley hoist units, one trolley hoist unit shall be marked “1” (or some other designation) on the trolley hoist or load block, and the other trolley hoist unit shall be marked “2” (or some other designation) on the trolley hoist or load block. The markings on the trolley hoists are to be visible to the operator and any signal person used in rigging the load. The controllers for trolley hoist 1 must be marked “1” (or other designation used on the trolley hoist), and the controllers for trolley hoist 2 must be marked “2” (or other designation used on the trolley hoist). All motions of multi-speed powered hoists should be started in the slowest speed available for that motion, and then the speed should be increased until the desired speed is obtained. At the beginning of hoisting motion, the load should be lifted only a few inches and stopped to check the holding brake before continuing with the lift. The hoist should be brought directly over the load before rigging the load to the hoist load hook. Failure to center the hoist over the load could cause the load to swing when it is lifted, or could cause side pulls or other forces to be transferred into the crane. Slack should be taken out of the chains, and slings, if used, before attempting to lift the load.

The operator must become familiar with the location and function of each button. Any hoist operator who is not familiar with a given installation SHALL operate the controller (WITH NO LOAD ATTACHED) to become familiar with the response of pressing each button and the relative movement of the hook block / body within the surroundings of the hoist installation. The markings on each of the pairs of motion control buttons may vary in format due to purchaser specifications. The hoist operator SHALL review the markings on each of the buttons and verify that the symbol represents the motion depicted on the button. For example, verify that the button with “UP” symbol actually activates the “UP” motion when depressed. Also, verify if the button activates a single speed motion or multiple speed motion. The button must be depressed slowly until fully depressed. Multi-speed buttons usually have distinct “steps” that can be felt during the full range of movement of the button. THE HOIST OPERATOR SHALL INSPECT AND VERIFY THAT THE CONTROLLER BUTTONS ARE LABELED AND ACTUALLY PERFORM THE MOTION INDICATED. IF THE MOTION LABELS ARE MISSING OR THE ACTIVATED BUTTON IS DIFFERENT FROM THE MOTION LABEL ON THE BUTTON, THE HOIST OPERATOR SHALL STOP IMMEDIATELY AND NOTIFY THE SUPERVISOR. IN CASE OF AN EMERGENCY, PRESS THE “RED” EMERGENCY STOP BUTTON TO DE-ENERGIZE ALL THE ELECTRICALLY DRIVEN MOTIONS CONTROLLED BY THE PUSHBUTTON CONTROL ASSEMBLY. ONCE THE “RED” EMERGENCY STOP BUTTON HAS BEEN DEPRESSED, THE BUTTON WILL REMAINED DEPRESSED IN A LOCKED DOWN MODE UNTIL ROTATED AND RELEASED.

The load, sling(s), or other lifting device should be fully seated in the saddle or bowl of the hook. Verify that the hook latch is operational and closes the throat opening of the hook. Make sure that the hook latch is not supporting any part of the load or the slings or device used to attach the load to the hook. Verify that the weight of the load to be lifted does not exceed the rated load capacity of the hoist. • Slack should be taken out of the hoisting chain(s) and slings, if used, before attempting to lift the load. • The load should be lifted only a few inches and stopped to check: o That the load is properly balanced; o That slings, if used, are properly positioned; o That load or sling is seated in the saddle, base, or bowl of the hook; and o That the hoist brake stops and holds the load before continuing with the lift. If a particular motion (hoisting motion / trolley motion / bridge motion) has multiple speeds, always start the motion with the slowest speed and then increase speed until the desired speed is obtained. Some multiple-speed hoists may have other features that affect the lifting motion and the operator should ® become familiar with the operation of such features. Refer to the STAGEMAKER COMPACT Concert Hoists Installation and Maintenance Manual furnished with the hoist. The operator must verify that all personnel are clear of the load and the path of the load, and that the load will clear all obstacles before lowering or landing a load. When lowering the load, if an electric chain hoist has multiple travel speeds, the lowering speed should be decreased to the slowest travel speed before stopping or landing the load. Place blocks under the load (“block load”) before landing if slings or other lifting devices must be removed from under the landed load. A load should never be left suspended and unattended unless specific precautions have been instituted and are in place to prevent the load from inadvertently lowering. Guards or barriers are to be utilized on the floor to prevent people from entering the area affected by the suspended load. When the hoist is not in use, the empty load hook / body hook should be raised and positioned above head level for storage. Seven feet or greater above floor level is recommended. It is Recommended that the Operator: SHALL be familiar with all operating controls of the hoist. SHALL be familiar with this Electric Chain Hoist Operator’s Manual provided by R&M Materials Handling, Inc., instruction and WARNING labels on the hoist, and the OPERATION section of ASME B30.16. SHALL be familiar with the operations to be performed. SHALL NOT operate hoist if any damage or malfunctions exist. SHALL report to the supervisor any damage or malfunctions. SHALL NOT operate hoist if it is tagged with an out-of-order sign. SHALL center hoist over load.

DO NOT LIFT LOADS OVER PEOPLE NOTICE HOISTS ARE INTENDED ONLY FOR VERTICAL LIFTING SERVICE OF FREELY SUSPENDED, UNGUIDED LOADS. DO NOT USE A HOIST TO LIFT LOADS THAT ARE NOT LIFTED VERTICALLY, LOADS THAT ARE NOT FREELY SUSPENDED, OR LOADS THAT ARE GUIDED. IF SUCH CONDITIONS EXIST, THE OPERATOR SHOULD CONTACT THE SUPERVISOR FOR INSTRUCTIONS. When trolleys are used with a hoist, trolley motion is the traverse travel motion direction of the trolley hoist unit. Control device markings for this motion should be as stated in the HOIST TYPES section of this manual. Regardless of the marking designation used, the operator should be fully aware of the direction of trolley motion that will occur when the control device is activated. If a load is to be lifted with the hoist hook before moving the trolley, refer to the HOIST MOTION section of this manual. If a powered trolley has multiple travel speeds, always start motion with the slowest speed and then increase speed until the desired speed is obtained. Motorized trolleys may have electronic devices that provide controlled acceleration of the motor and offer a soft or controlled start. When bringing the trolley to a stop, if a powered trolley has multiple or variable travel speeds, it is recommended that the travel speed be decreased to the slowest speed before stopping the trolley to minimize load swing. It is Recommended that the Operator: SHALL NOT engage in any activity that will divert the attention of the operator. SHALL NOT lift, lower, or transport a load with the hoist until the operator and all other personnel are clear of the load and the path of the load. SHALL verify that the load and hoist will clear all obstacles before moving or rotating the load. SHALL avoid moving loads over personnel. SHALL NOT lift, lower, or transport personnel by means of the hoist, trolley, hoist hook, or load. SHALL slowly inch the load hook into engagement with the load to eliminate load chain slack and minimize impact loading the hoist. SHALL avoid unnecessary inching and quick reversals of direction.

SHALL only lift the load a few inches to verify that the hoist braking system is functioning properly before continuing with the lift. SHALL avoid swinging of the load or hoist load hook when the trolley (if applicable) or hoist is traveling. SHALL avoid sharp contact between trolleys or between trolley and stops (if applicable). SHALL NOT use the hoist load limiting device or load warning device (if provided) to measure the load to be lifted. SHALL NOT use hoist limit devices as a normal means of stopping the hoist. SHALL NOT use the slip clutch as a normal means of stopping the hoist SHALL NOT permit continuous contact between the hoist body and the load block / slack fall stop. 5.4 Parking the Load It is Recommended that the Operator: SHALL NOT lower a load with the hoist until the operator and all other personnel are clear of the load and the path of the load. SHALL verify that the load will clear all obstacles before lowering the load. SHALL block loads before landing if slings or other lifting devices must be removed from under the landed load. SHALL exercise care when removing a sling from under a landed and blocked load. SHALL NOT leave a suspended load unattended unless specific precautions to prevent the load from inadvertent lowering have been instituted and are in place. SHALL position the hoist load block and load hook / body above head level for storage when the hoist is not in use. Seven feet or greater above floor level is recommended. Hoist Limit Devices Powered hoists must be equipped with an upper limit device that will prevent the hoist from exceeding the upper limit of travel. Depending on the shape or size of the load being lifted, it may be impossible for some part of the load to come into contact with some part of the hoist, trolley, crane, or building structure before the hoist/load block activates the slip clutch or reaches the upper limit of travel. The operator must consider this possibility when it is required to lift the load to a level of close proximity to the hoist. Powered hoists may have additional travel limit devices depending on the specific purchase specifications of the hoist. However, in such cases, the upper limit device that is activated to stop the upper limit of travel is considered the primary upper limit device. September 19, 2005 0.doc 25 STAGEMAKER® OP MAN 2005- ® R&M Materials Handling, Inc Springfield, Ohio USA STAGEMAKER® COMPACT Concert Hoist Operator’s Manual : 800-955-9967 www.rmhoist.com September 2005 Operation of the primary upper limit device, on powered hoists, is one of the items the hoist operator must check during the daily inspection to be performed at the start of each shift, or at the time the hoist is first used during each shift. The primary limit device that controls the upper limit of travel is an emergency device only. It shall not be used as an operational means to stop travel during normal operations. 5.5 General Recommendations It is Recommended that the Operator: SHALL know hand signals used for hoist and crane operations if a signal person is used in the operation, and accept signals of only persons authorized to give hand signals. SHALL obey a stop signal regardless who gives it. SHALL NOT adjust or repair a hoist unless qualified and authorized to perform maintenance. SHALL NOT use the hoist limiting device or load warning device (if provided) to measure the load to be lifted. 5.6 Recommended General Do Not’s It is Recommended that the Operator: DO NOT operate a hoist that is damaged or has any actual or suspected mechanical or electrical malfunction. DO NOT attempt to lengthen load chain or repair damaged load chain. DO NOT use the load chain, any part of the hoist, or the load block and hook as a ground for welding. DO NOT allow a welding electrode to be touched to the load chain or load hook. DO NOT remove or obscure any instructions, warnings or warning labels on the hoist. DO NOT walk under a suspended load or allow other personnel to walk under a suspended load. DO NOT perform or allow any other person to perform ANY work on a suspended load that requires a worker to be positioned under the suspended load.

DO NOT PERFORM ANY WORK ON A SUSPENDED LOAD THAT REQUIRES A WORKER TO BE POSITIONED UNDER THE SUSPENDED LOAD. IF IT IS ESSENTIAL THAT A WORKER BE POSITINED UNDER A SUSPENDED LOAD TO PERFORM WORK ON THE SUSPENDED LOAD; SUCH WORK SHALL NOT BE STARTED OR PERFORMED UNTIL OTHER AUXILIARY SUPPORTING MEANS ARE PLACED UNDER THE SUSPENDED LOAD. FAILURE TO USE OTHER AUXILIARY SUPPORTING MEANS COULD RESULT IN SERIOUS BODILY INJURY OR DEATH, AND/OR PROPERTY DAMAGE. 5.7 Operator Hand Signals Hoist operators are normally involved in rigging the load, attaching the load to the hoist, and other tasks related to the load for which they have skills in addition to those required for operation of the hoist. Therefore, in addition to the specific information required to operate the hoist, hoist operators should be familiar with rigging procedures and practices. In many applications, a single hoist may be operated by several workers as part of their regular job responsibility. In some instances, when a hoist is used on an overhead crane or when a hoist is used as a component in a larger material handling system, other persons, such as a signal person, in addition to the hoist operator, may be involved. Operations that involve an operator (either hoist or crane) and a signal person (normally the rigging or hookup person) require hand signals between the signal person and the hoist or crane operator unless voice communication, such as telephone, radio, or an equivalent method, is used. Where hand signals are used, the operator must be familiar with and understand hand signals, and must respond to hand signals from the designated signal person except to obey a stop signal regardless who gives it. When voice communication between the signal person and the operator is used, a dedicated channel is required in order to eliminate any commands from other personnel in the area that could be confusing the operator. Refer to standard hand signals, as shown in ASME B30.2, for use in overhead hoist, and overhead crane and gantry crane operations. A copy of the standard hand signals should be posted where the application requires both an operator and a signal person. Special hoist or crane operations may require the use of additional hand signals or modifications of the standard hand signals. When special signals are required, they should be documented by the crane owner / user, and agreed upon, and understood, by the signal person and hoist or crane operator. Special signals should not conflict with standard signals. Operators, rigging personal, signal persons, and maintenance personnel SHALL be required to know the location and operation of the main power supply disconnect all hoists (and cranes, if applicable) in the area. NOTE: Do not release operators and users from the responsibility of obtaining, reading, and fully ® understanding the strict execution and observation of ALL procedures in the STAGEMAKER COMPACT Concert Hoist OPERATOR’S MANUAL. This will better qualify personnel to operate the hoist in a safe manner. ___________________________________________________________________________________ _____ September 19, 2005 0.doc 27 STAGEMAKER® OP MAN 2005- ® R&M Materials Handling, Inc Springfield, Ohio USA STAGEMAKER® COMPACT Concert Hoist Operator’s Manual : 800-955-9967 www.rmhoist.com 6 September 2005 APPENDIX – A – DEFINITIONS OF ELECTRIC CHAIN HOIST TERMS below-the-hook lifting devices – Devices that are not normally reeved onto the hoist chain, such as hook-on buckets, magnets, grabs, and other supplemental devices used for ease of handling certain types of loads.
