Section 1: Quality Benefits

o Complete installation & Service manuals accompanies each shipment. o All products are continuously evaluated & engineered for ease of installation and longevity of service. o Technical assistance is second to none when… o On time shipments are made when you want them. You specify the ship date, and EMS will call you 24-48 hours prior to that date to verify project schedule, address, and contact person for 24 hr delivery notice.

o APPLICATIONS

• Department Stores, Sports Arenas, Hotels, Light to Medium Commercial, Light Industrial

Normally these elevators are used for hand truck loading that places elevator in loading Class A.

The elevator is not subjected to high moisture or extremely dusty conditions. The electrical devices in the hoistway and machine room (for power doors) are NEMA 1. Freight handlers will be the only passengers allowed on the freight elevator.

• Manufacturing Plants, Warehousing Facilities, Medium to Heavy Industrial

These elevator doors are designed to withstand the rugged duty of industrial fork lifts driving onto and off of the elevator with a loading of Class C1, C2 or C3 (see Technical Data). The trucking sills are reinforced with structural steel to withstand elevator capacities of up to 60,000 lbs. EMS closed loop control will reopen any door that might bounce close during trucking across the landing door. The incidental dust that may occur from the industrial facility will not require any special

Nema classification for the electrical devices. If the facility has excessive dust generated by the manufacturing process, request NEMA 12 devices. If the elevator is in a high moisture area of the facility or there is the need to periodically wash down the hoistway, request NEMA 4 devices.

• Food Processing Facilities, Water Treatment Plants, Open Elevator Shafts, Corrosive Environment

Facilities

These elevators are normally Class C1 or C2 for industrial forklift use. The landing doors and car door/gate are often constructed of stainless steel to resist the harsh environment. The electrical devices are rated NEMA 4X to protect against water entry and to resist corrosion.

• Loading Docks, Rooftop Landings, Exterior Openings

We recommend that any landing door that opens to the exterior of the building be equipped with weatherstrip to protect the hoistway from exterior temperatures and moisture. The landing doors should have a factory or field applied rust inhibitive enamel finish.

• Chemical Plants, Paint or Adhesive Facilities, Oil Refineries

The elevator may fall under the light industrial or heavy industrial category. If the elevator is in an area that can be exposed to explosive gases or dust, the electrical devices will need to have the appropriate rating for the environment in which they will be operating. A NEMA 7 rating applies to explosive gases, and a NEMA 9 rating applies to explosive dust. The facility engineer will normally provide the classification for the elevator which will include the Class, Group and Division for the explosive environment.

Section 2: Hoistway Doors

o Hoistway Door Types

Door panels are constructed with an upper and lower panel where the lower panel slides down between the building sill and car platform. The top of the lower door is used support trucking loads onto the elevator. The upper panel simultaneously travels upward above the opening to provide a clear opening. The two panels counterbalance each other. No counterweight is required.

• Vertical Bi-Parting Pass Type

Pass doors are required where the floor to floor height is not high enough to allow the upper door panel to open with out interference with the door above. See Technical Data: Space Requirements for more details.

Bi-Parting

The parting line for the door panels is 1/3 of the opening height above the sill in lieu of the centerline of the opening. The result is a shorter lower door panel that requires less room in the pit area. See Technical Data: Space Requirements for more details.

• 1/3-2/3 Bi-Parting Pass Type

When using the 1/3-2/3 Bi-Parting door the upper panel is larger and requires more space above the opening. When the floor to floor height is not sufficient for the larger door, the door becomes a pass door to prevent interference with the door above. See Technical Data: Space Requirements for more details.

• Two Section Compounding Upper Panel Bi-Parting

This arrangement is used when the overhead space is not adequate for the upper door panel to travel above the top landing opening. The upper door is constructed as two panels that pass each other as they open. See Technical Data: Space Requirements for more details.

• Two Section Slide Up

All Slide Up & Slide Down doors require separate counterweights. Two section slide up doors are recommended for elevators with excessive loading requirements. With both panels traveling up to open, all trucking weight is transferred directly from the building floor to the elevator platform.

Projecting sills are required beyond the hoistway wall for supporting the slide up type doors. These doors can be more costly because of the additional counterweight and weight troughs that are not required on traditional bi-parting type doors.

• One Section Slide Up

One section slide up door is used similarly to the two section, however, the size of the opening may restrict its use due to shipping requirements. The one section slide up door requires less sill space projecting into the hoistway than the two section configuration.

o UL Labeling

UL ‘B’ label provided on doors up to 13’ 6” wide by 12’ 0” high. UL ‘B’ oversized label is provided on doors larger than 13’ 6” wide by 12’ 0” high up to 16’ 10” wide by 15 0 high. Doors manufactured larger than the sizes listed are built to the same stringent conditions but are beyond the capabilities of testing.

o EMS Operating Cams

• Retiring Cams

• Required on all power operated doors.

• On Manually operated doors, retiring cams are required to operate the lowest landing door locks where the pit is greater than 5’0”. Retiring cams are also required on elevators with a rise greater than 15’0”.

(Note: Requirements vary with some local codes)

• Stationary Cams - May be used on manually operated doors that do not require retiring cams.

o Operation

• Power Operated Doors are recommended for doors with an opening size greater that 10’ by 10’ or when elevator is intended for industrial truck use.

• Manually Operated Doors. All EMS manual landing doors are upgradeable to power operation without the costly need for complete replacement.

Electrical Devices

.

EMS electrical hardware meets NEMA 1 requirements. Hardware to meet all other NEMA ratings available upon request. See Technical Data: NEMA Ratings for more details. o

Weatherstrip

.

Can be provided for exterior doors or doors at refrigerated levels to minimize airflow into the hoistway. o

Sound Deadening

.

EMS can provide a latex bituminous coating to the shaft side of the hoistway doors. The doors receive a factory finish over the coating. This will minimize the sometime metallic sound that can occur during trucking or operation of the doors. The textured material will also help minimize noise transmitted from the hoistway to the hall or corridor. This coating is often used in hotels or office environments where noise can become an issue. o

Insulated Doors

.

Hoistway doors are constructed to the same rigid requirements as our steel plate doors. We then apply insulating panels (R-7.5) to the shaft side of the doors and then cover with a 16 ga. steel shaft side sheet that is welded in place. o

Restricted Access Locks

.

Electric lock to prevent operation and access to designated landings. These are used on exterior applications and secure floors of buildings. Operation can be activated by typical methods: key switch, card reader or remote security station. Lock status monitoring is available for remote signaling. The location of these locks in the hoistway are governed by and in some cases prohibited by national codes. o

Thrust Angle

.

Used to transfer horizontal loads subjected to the lower door during trucking, back to the building structure to minimize damage to lower door panel, guide shoes and tracks. o

Finishes

.

Many finish coatings are available. EMS standard finish is a medium gray base finish. This finish acts as a primer to most top coat finishes, or can remain as the only finish if not subjected to high moisture or UV rays. Finish enamels, epoxies, & zinc coatings can be factory applied. Color charts are available upon request or provide customer specified color and color chip. Floor designation numbers can also be applied to shaft side of hoistway doors.

Typically 6” high markings. o

Stainless Steel

.

Many construction methods exist for stainless steel hoistway doors and specific use of each particular application must be taken into account to maintain cost and provide lasting performance. Each application must be evaluated to determine whether stainless steel is being used for aesthetic value, corrosion protection, or both.

ƒ Appearance .

To provide a grained finish on the room side of the door, a light gauge

#4 finish stainless steel fascia is applied to a standard factory finish carbon steel plate door. Other textured finishes can also be applied in this manner, such as #5WL &

#6WL. Cost will vary with type of finish.

ƒ Corrosion protection .

Constructing freight doors with stainless steel will significantly increase the cost of the door panels. EMS has chosen a four level system to constructing doors of stainless steel with level 1 being the least expensive. Note!

Appearance of the room side of the door will be a dull silver finish with weld marks and cleaning abrasions visible. o

Level 1

.

The door frame is constructed of carbon steel with all sheet metal constructed of #300 series stainless steel. This is recommended when doors may be periodically exposed to high moisture.

St. Louis, MO

800-489-4889

St. Louis, MO

800-489-4889 o

Level 2

.

The majority of the door frame is constructed from #300 series stainless steel, including perimeter frame, sheet stiffeners, & trucking flat bar.

Structural channels are zinc coated carbon steel. Miscellaneous chain arms & hitches are also zinc coated carbon steel. This method coupled with Nema 4 electrical devices are used in areas of continuous high moisture. The economics may warrant this over a level 3 construction if the doors are to sustain extreme use and their replacement will most likely occur prior to the carbon steel deterioration. o

Level 3

.

The entire door panel is completely constructed of #300 series stainless steel. All framing, sheeting, hardware and fasteners of the door panel are constructed of stainless steel. In addition to the door panel construction, the door support chains and chain hardware is constructed of stainless steel. The door guide shoes are constructed of cast bronze to reduce oxidation. This construction coupled with Nema 4X electrical devices is suitable for high moisture or corrosive areas that will require wash down duty. o

Level 4

.

The door panels, support chains & guide shoes are constructed as described in level 3 above. In addition, the door tracks, track hardware, lock hardware and miscellaneous brackets will all be constructed from #300 series stainless steel.

ƒ Any level of corrosion protection can be coupled with the grained stainless steel laminate to achieve superior corrosion resistance without compromising room side appearance.

Section 3: Car Door/Gate

o Car Door/Gate Types

A single section gate is used when there is adequate overhead in the shaft for the complete gate panel to open. It is the most cost effective application.

• Two Section Compound

This product is provided on elevators when the available overhead is less than that required for the opening height dimension plus the panel height. Normally the lower gate panel is slightly larger than half the opening height and the upper panel height varies depending on opening height. This is the most economical of the two section gate types.

• Two Section Ratio Driven (Differential)

This is the more expensive two section gate arrangement. Both upper and lower gate panels are the same size, which allows its use on elevators where available overhead space is a minimum.

Both panels are independently counterweighted. The counterweight trough requires more space on the front of the car platform and cab wainscot must be set further back than more standard gate arrangements.

o Operation

Gate

Gate

o Features

o EMS single section car gate is constructed of 1-1/2” square, #10 gauge wire mesh, set in a perimeter structural angle frame (two section gates will use mesh that rejects a ½” ball to comply with national codes). Angle and flat bar ribs are utilized to provide reinforcing across the body of the gate panel. The car gate will close off the entire width of the entrance cab to a height 6’-0”. o Gate Tracks. Formed steel “C” section of 3/16” thick material. Mounting slots are provided for track mounting to assist in setting the track gauge. o Single section mesh gate that slides up to open. o Car gate is equipped with support chains that connect the counterbalance weight. o Counterbalance weight utilizes a guide system throughout its entire travel within the enclosed steel through. o A contact switch is provided to interrupt the running of the car in the event the car gate is open. o Support chains ride over ball bearing supported sprocket assemblies. o Power operated gates are equipped with a reopening device across the bottom of the gate panel. o Retiring cam and cam power unit are arranged for ease in mounting to the gate tracks.

Light Curtain Detection System

.

Multiple beam protection is provided in the path leading the car door/gate to detect an obstruction prior to contact with the car door/gate. EMS standard contact reopening device will remain on the car door/gate and will be fully functional as a redundant safety device. o

Wood Bumper Guard

.

A hardwood bumper can be provided across the car door/gate width on elevators with both front and rear openings. It is used to help reduce damage to the closed car door/gate during loading & unloading of the elevator car. The typical bumper rail is constructed of 2” x 6” oak, and can be located from 8” off the floor to 24” off the floor, with 12” being standard. o

Solid Panel Construction

.

The solid panel car door is fabricated similar to the steel plate door with a perimeter angle frame and angle sheet stiffeners. The smooth or sheet side of the car door is facing the inside of the car. Angles will be visible on the perimeter and corridor side of the car door. A lift bar will be provided on the car side of the car door. Typically these car doors will be made full opening height of the cab and often will require two section panel construction due to limited hoistway overhead space. o

Passenger Use Package

.

Included is a light curtain detection system that monitors the path of the car door for possible obstructions. Restrictor locks are provided to lock the car door closed while the car is not at a selected landing. The car door supplied will be solid panel construction to close the entire car opening. Also provided is a visual and audible signaling device to alert riders that car door closing sequence is initiated. o

Stainless Steel

.

Like landing doors there are several construction methods for stainless steel car doors/gates. Each application must be evaluated to determine whether stainless steel being used for corrosion protection, or for aesthetic and corrosion protection purposes.

ƒ Corrosion protection only

.

The mesh car gate is constructed entirely of #300 series stainless steel structural frame and mesh. Note! Appearance of the car gate will be a dull silver finish with weld marks and cleaning abrasions visible.

ƒ Appearance & Corrosion protection

.

To provide a grained finish on the car side of the car door, the car door is constructed of #4 finish stainless steel. The car door will be solid panel construction and typically cover the full opening height of the cab. Other textured finishes can also be applied in this manner such as #5WL & #6WL.

Section 5: Control

• EMS Patent Pending* Closed Loop Control – Elaborate!!!

• EMS controller is arranged with a programmable controller processing the operating commands for the doors, gates & retiring cams.

Features

• Sequence Operation. Sequence operation for freight elevators is defined as hoistway doors opening substantially prior to car door/gate opening. In closing, the car door/gate closes substantially prior to the hoistway door closing.

• Momentary Pushbutton Operation. Momentary pressure on the open or close pushbutton is standard operation for all EMS freight installations.

• Fireman’s Operation. EMS controller is designed to provide Fireman’s Phase I, II, & Fireman’s Hold door operation in accordance with national and local codes.

• Hold Down Feature. This feature will re-open the doors if they should try to bounce closed during trucking across the lower door panel. This feature is standard on the EMS Closed Loop System and can be field activated by entering a simple code sequence.

• Automatic Opening. EMS doors are arranged to receive an input signal from the elevator control to trigger an opening sequence.

• Automatic Closing. With a field selectable time duration between 5 sec. and 5 minutes is available on all EMS controllers. It can be field activated by entering a simple code sequence. See EMS

Service Manual for details.

• Supply Voltage. EMS controller can be arranged to operate on input voltages ranging between

208VAC to 600VAC, 3 phase, 50/60 cycle. Any transformers required will be supplied by EMS Group.

Features

• Constant (Maintained) Pressure Close Operation. This feature is available on all EMS controllers and can be field activated by entering a simple code sequence. See EMS Service Manual for details.

• Remote Closing. This control feature is available and requires an input from the elevator controller.

• Sounder/Flasher.

• Nudging. Similar to passenger elevator doors, EMS doors can be arranged to deactivate the reopening devices on the car door/gate and begin to close the car door/gate at approx. 1/6 the normal closing speed. Nudging would only activate after several normal closing cycles have been initiated.

• Environment. EMS controller is mounted in a NEMA 1 enclosure. Enclosures to meet all other NEMA ratings are available upon request. See Technical Data: NEMA Ratings for more details.

Section 6: Hoistway Construction

o Landing Door Opening Framing

• Flush & Plumb. The landing sill, jambs, and lintel (header) must all be flush on the shaft side of the wall. No wall construction material can project beyond the shaft side face of the framing. The need for having PLUMB jambs cannot be overemphasized. Once the elevator rails are set plumb, any variation of the entrance jambs from plumb will cause variations of the running clearance between the platform and the bi-parting freight door. Code limits this running clearance between ½” to 1-¼”. When shafts contain both front and rear entrances this condition becomes critical.

• Frame Projection. EMS recommends to arrange the hoistway so the entrance framing projects approximately ½” into the hoistway from any wall line that has freight doors. When showing clear hoistway on layout drawings, dimension the clear hoistway between the front and rear entrance framing and show the rough hoistway being ½” larger for in-line openings, and 1” larger for elevators with both front and rear openings. This will allow for variation during construction where the distance from the jamb to back wall (or rear jamb) can be held, while the ½” frame projection can vary if need be to maintain the clear hoistway dimension.

• Jamb Extensions. For best results steel entrance jambs should extend above each landing to the floor beam above or for elevators with large travel between openings a minimum of ½ of the opening height above and below the opening. Having plumb & flush steel jambs to mount the full length of the door track will ease the installation and assure smooth operation of the freight doors. construction

• CMU (concrete block). EMS recommends that the landing door jambs continue to the floor beam above. If steel jambs do not continue to structure above, it is recommended that the blocks in the area of the door tracks be filled for use with anchors.

• Poured Concrete. Entrance frames are only required in the opening only. Concrete anchors will be used to secure the track above and below the opening. Note: The shaft side of the hoistway is to be flush and plumb. We recommend having the entrance framing project ½” into the hoistway to allow for swelling or inconsistencies of concrete without interfering with track installation.

• Drywall. Normally used to meet seismic requirements. Landing door jambs are required to extend from the opening sill to the floor beam or building structure above the opening to support weight of the freight doors. NOTE: Drywall alone is not adequate to support the door tracks above and below the door opening and will not meet Underwriters Labeling requirements. Entrance framing must be sized to carry the weight of the door equipment as well as the transmitted loads of the freight being trucked across the lower door panel during loading and unloading.

• Brick. Hoistways constructed of all brick require track mounting brackets and thru the wall fastening.

Section 7: Technical Data o Loading Class

• Class “A”: Weight of any one item or loaded truck cannot exceed 25% of the rated capacity of the elevator. Loads must be handled on and off car platform manually or by hand truck.

• Class “B”: Elevator is used to carry automobile trucks or passenger automobiles. Doors must carry

75% of the rated load divided into two equal parts, 5’0” apart.

• Class “C1”: Industrial truck loading where truck is carried by the elevator. For rated capacity of

20,000 lbs. or less*, doors must carry 80% of the rated capacity divided into two equal parts, 30” apart.

• Class “C2”: Industrial truck loading where truck is not carried by the elevator, but used only for loading and unloading. For rated capacity of 20,000 lbs. or less*, doors must carry 80% of the rated capacity of the elevator, or 80% of the loaded truck weight, whichever is greater, divided into two equal parts,

30” apart.

• Class “C3”: Other loading with heavy concentrations where trucks are not normally used, consult

EMS Group.

Panels are to be constructed of minimum #12 gauge steel sheet set into structural angle frame with vertical angle reinforcing

16” maximum on center. Upper edge of lower door shall be reinforced for specific rated load and class of loading. Lower edge of upper panel shall have a fire resistive non-shearing, non-crushing meeting edge to close distance between rigid door sections, which must be maintained at not less than ¾”. All construction must comply with latest version of ASME A17.1 and local codes and as specified in manufacturers Underwriters Laboratories Fire Door Construction Procedures.

Door tracks shall be minimum #7 gauge formed steel fastened to entrance jambs. Door stops to transmit panel sill loads to the building sill structure.

Panel guide shoes shall have milled grooves and be adjustable, ductile iron and completely replaceable. Nylon or other composite material guide shoes with or without sheet metal shell are not permissible.

Doors which are no more than 13’6” wide and 12’0” high shall bear Underwriters laboratories 1 ½ hour (B) labels. Larger doors

(no more than 16’10 ½” wide or 15’0” high) are to bear an Underwriters laboratories “Classified Oversize Door” label. Still larger doors must be built to the same rigid U.L. standards and certified by the manufacturer.

Manual doors are to be arranged for future power operation.

All doors are to have a 4” X 10” clear wire glass vision panel at approximately 5’0” above floor, as permitted by door construction. Vision panel glass is to be covered with perforated steel plate containing ¾” holes on 1” centers.

Vertical Lift Car Gate:

Gate panel shall be 6’0” high #10 gauge woven steel wire with structural steel frame and reinforcing. Panel to slide vertically to open on steel tracks. Panel guide shoes shall have milled grooves and be adjustable, ductile iron and completely replaceable.

Nylon or other composite material guide shoes with or without sheet metal shell are not permissible. Panels to be hung on steel roller chain and fully counterweighted for ease of operation. If a single counterweight is used to support the car gate, then a minimum of two chains must connect independently and directly to the gate counterweight. Each chain is to be individually adjustable for length at connection to car gate panel. If required by restricted overhead, gate to be furnished with double panel sections.

Power operated gates are to have a reopening device which causes gate to stop and reopen if it should meet with an obstruction while closing, as well as sequence gate and door operation.

Manually operated gate is to be arranged for future power operation.

Control (Power Operated):

A control panel shall be furnished to govern the opening and closing of doors and gates as well as retiring cam operation, reopening device function and sequence operation. Control shall monitor the position of doors and gates at all times without the use of door & gate limit switches. Deceleration points shall be automatically adjusted by control so that final open and final closed positions are reached smoothly without shock or jarring of doors or gate and without stopping ‘short’ of fully open or closed position and then restarting. Initial setting and adjusting of full open and closed positions shall be established through operation of ‘open’, ‘close’, and ‘stop’ push buttons inside car. For safer operation, opening and closing speeds for doors & gate are to be independently and fully adjustable to allow any closing speed up to A17.1/B44 Code maximums. Control shall be automatically operational upon application of power. After automatic safety shut down, control shall restart upon pressing ‘Door

Stop’ push button in car. ‘Constant Pressure’ close, ‘Momentary Pressure’ close or ‘Timed Automatic’ closing shall be field selectable. Control is to be completely front wired, to have clear sight line to terminal strips for field connections and mounted in

NEMA 1 cabinet with hinged swing door. Retiring cam operation is to be silent, without bounce and without the use of dampening devices. Cam ‘drop’ is to be powered down with cam motor, not by gravity alone. All control components are to be commercially available and nonexclusive to control supplier.
