Platform And Sling:  The platform shall have a fabricated frame of formed and structural steel shapes, gusseted and rigidly welded.  Flooring shall be wood top floor laid over steel subfloor.  Finished floor covering shall be provided on the top of the car platform, by others.  The underside of the platform will be fireproofed.  The sling shall consist of heavy steel channel stiles properly affixed to a steel crosshead and bolster, with adequate bracing members, to remove all strain from the car enclosure.  Steel bumper plates shall be affixed to the bottom of the bolster channels, and a platen plate with sound deadening material to be furnished for fastening sling to plunger.

Cylinder:  The cylinder will be machined from steel pipe with a machined steel flange at the upper end and a heavy steel bulkhead welded in the lower end.   The cylinder will be provided with a suitable steel fitting for connecting to the oil line and with an air bleeder.  Heavy steel brackets, suitable for mounting to the elevator pit channels will be welded to the cylinder.

Protective Wrap:  The cylinder will be protected by a single wrap of polyethylene tape bonded to the cylinder with a special corrosion resistant bonding agent.  This wrap is designed to provide long term underground protection.

Power Unit Isolation:  The entire unit shall be mounted on vibration dampeners, isolating the unit from the structure.

Hydraulic Muffler:  Designed to reduce pulsation and noise which may be present in the flow of the hydraulic fluid.  Muffler will be installed in oil line concealed inside the power unit.

Controller:  Microprocessor, with all components, switches to be mounted in a steel panel designed for mounting on the power unit.

Automatic Two Way Leveling:  An automatic two way leveling device will be provided so that the car will approach landing stops at reduced speed from either direction of travel.  The leveling device will, within it's zone, be entirely independent of the operating device and is designed to automatically stop and maintain the car approximately level with the landing, regardless of change in load.

Holes Arrangement Option:
Plunger: The Plungers shall be in a twin jack arrangement.  One jack located on each side of the car.  The plungers shall be accurately ground and polished seamless steel.  The bottom of the plungers shall be fitted with a heavy steel disc, welded in place and provided with a suitable extended edge to provide a positive stop designed to prevent the plunger from leaving the cylinder.  The top of the plunger shall be provided with an internal welded steel disc drilled and tapped for fastening plunger to gussets which fasten to the crosshead members.
Cylinders: The cylinders shall be machined from steel pipe with a machined flange at the upper end and a heavy steel bulkhead welded in the lower end.  The cylinders shall be provided with suitable steel fittings for connecting to oil line and with air bleeders.  Heavy steel plates suitable for mounting to elevator pit channels shall be welded to the bottom of the cylinders.

Emergency Lighting:  Provide emergency light for the elevator.   Lights shall be located in front return of cab and be automatically turned on not more than ten seconds after normal lighting power failure.  Emergency lighting units shall meet ANSIA17.1 code requirements.

Electronic Passenger Sensing Device:  DUAL solid state electronic detectors designed to operate as described below shall be provided at the entrance of the elevator.  In addition, an electro mechanical reversal edge shall be provided on the leading edge of the cab door.  After a stop is made, the doors shall remain open as long as the electronic detector senses the presence of a passenger or object in the door opening.  The circuitry will be arranged to deactivate the electronic detectors, should the fail to operate.  However, the electromechanical reversal edge will not be deactivated be failure of the electronic detector or its removal from the circuitry by means of manual switch.

Plunger:   The plunger will be accurately ground and polished seamless steel.  The bottom of the plunger will be fitted with a heavy steel disc, welded in place and provided with a suitable extended edge to provide a positive stop, designed to prevent the plunger from leaving the cylinder.   The top of the plunger will be provided with an internal welded steel disc, drilled and tapped for fastening the plunger to the car platen plate.

Packing Gland:  A packing gland with guide bearing, wiper ring and packing especially designed for hydraulic elevator service will be provided.  An oil collector ring and drain hole will be furnished.

Power Unit Submersible Type:  Oil pumping and control mechanism shall be compactly and neatly designed in a self contained unit, steel outer base with tank supports, floating inner base for mounting motor pump assembly overheand oil reservoir with tank cover and controller compartment with cover.  The pump shall be especially designed and manufactured for oil hydraulic elevator service.  It shall be of the positive displacement type, inherently designed for steady discharge with minimum pulsation to give smooth and quiet operation.  Output of pump shall not vary more that 10% between no load and full load on the elevator car.  The motor shall be especially designed for oil hydraulic elevator service, of standard manufacture, and of duty rating to comply with herein specified speeds and loads.

Sound Isolating Coupling:  A minimum of one shall be installed in the oil line between pump and jack.

Valves:  Control valves including safety check valve, up direction valve with high pressure relief, including up leveling feature will be mounted in a compact unit assembly.  Control valves will be solenoid operated and designed to open and close gradually to give smooth control.  All valves will be readily accessible for adjustment and have emergency manual lowering features.

Failure Protection:  The electrical control circuit shall be designed so that if a malfunction should occur, due to a motor starter failure, oil becoming low in the system, or the car failing to reach a landing in the up direction within a predetermined time, the elevator car will automatically descend to the lowest terminal landing.  If power operated doors are used, the doors will automatically open when the car reaches that landing to allow passengers to depart.  The doors will then automatically close, and all control buttons except the "DOOR OPEN" button in the car station, shall be made inoperative.

Car Top Inspection Station:  Car top inspection station with an "EMERGENCY STOP" switch and will constand pressure "UPDOWN" direction buttons shall make the normal operating devices inoperative and give the inspector complete control of the elevator.

Hoistway Entrances:  Hoistway entrances of the hollow metal, horizontal, sliding type.  The entrances will include:  unit frames, flush design door panels, sight guards, extruded aluminum sills, strut angles, headers, hanger covers, fascia plates, toe guards, dust covers, ad necessary hardware.  Standard finish will be as follows (frames):  steel with plastic laminate finish.   Facias, hanger covers, toe guards and dust covers will have manufacturer's standard enamel finish.  Structural members will have prime coat finish.  Sills, strut headers, hanger covers, and unit frames will be erected prior to the erection of the rough walls and set in proper relation to the car guide rails.  Door panels will be installed after the walls are finished.
