4.4 SEMI-ENCLOSURE
4.4.1 The Vertical Platform Lift will be equipped with a self closing lower entrance, platform gate, and top landing gate. The lower landing and platform gates will open simultaneously when at the lower landing.
4.4.2 The non-exit sides of the platform are protected by 42 1/4" high platform walls.
4.4.3 An aluminum frame enclosure with steel inserts that extends a minimum of 4" above the upper landing is provided around the platform to prevent access to the underside of the platform. A smooth vertical fascia or wall shall be fastened securely from the upper landing sill to the lower landing sill.
4.4.4 All gates are to be equipped with interlocks to prevent them from opening if the unit is outside the door zone.

4.5 PUMP UNIT AND CONTROLS
The drive unit and controller shall be enclosed in the mast. The controller and pump unit shall be pre-wired and tested before shipment. Control circuitry is to be PCB mounted as an integral unit. The pump unit shall included the following features:
4.5.1 Smooth stops at each landing shall be an inherent feature.
4.5.2 Adjustable pressure relief valve.
4.5.3 Manually operated DOWN valve to lower the lift in an emergency.
4.5.4 Pressure gauge with quick connect fitting.
4.5.5 Pressure gauge isolating valve (shut off valve) manually operated.
4.5.6 Gate valve to isolate cylinder from the pump unit.
4.5.7 Fixed pressure compensator flow control valve to set maximum DOWN direction speed regardless of load.
4.5.8 Electrical solenoid for DOWN direction control.
4.5.9 Emergency power raising and lowering by battery power.

4.6 CYLINDER AND PLUNGER
4.6.1 The cylinder shall be constructed of steel pipe of a sufficient thickness and suitable safety margin. The top of the cylinder shall be equipped with a cylinder head with an internal guide ring and self-adjusting packing.
4.6.2 The plunger shall be constructed of a steel shaft of a proper diameter machined true and smooth. The plunger shall be provided with a stop electrically welded to the bottom to prevent the plunger from leaving the cylinder.

4.7 LEVELING DEVICE
