pump module consists of the hydraulic pump, the manual hand pump and electrical components that power the lift electric/hydrau- lic systems.
Lift Frame: The lift frame consists of the base plate, two towers, the parallel arms, the vertical arms, platform pivot arms and the handrails. The two main

hydraulic cylinders are housed in the parallel arms. The electrical/ hydraulic powered lift frame components mechanically unfold, lower, raise and fold the lift platform assembly.
Bridge Plate: The bridge plate assembly consists of the bridge plate (striker back) and the bridge plate extension (flap). The hinged bridge plate assembly bridges the gap between the lift platform and the vehicle floor when the platform is positioned at floor level. Note: The bridge plate extension (flap) is bolted to the bridge plate (as shipped) in the Lift Terminology Illustration. In stepwell applica- tions where additional platform length is required, the extension plate may be bolted to the heel (inboard end) of the platform.
Dual Handrails: Dual handrails are provided for wheelchair passenger use. The handrails automatically unfold to the deployed position when the platform unfolds and fold auto- matically to the stowed position when the platform folds. The passenger may choose to grip the handrails when on the lift platform (if applicable). Note: An addi- tional UP/DOWN control switch is built into the right (front) handrail.
Platform Assembly: The lift platform assembly consists of the steel tubing frame with grating surface upon which the wheel- chair is positioned, the outboard roll stop, roll stop latch, the side entry roll stop (SE only), and the hydraulic cylinder assembly that powers the outboard roll stop.
