Lift Terminology
Lift Components:
Refer to the Lift Terminology Illustrations on pages 2 and 3.
Pump Module: The remote mounted pump module consists of the main hydraulic pump, the manual hand pump, the logic control board and other electrical components that power the lift electric/hydraulic systems.
Lift Housing: The lift housing is the metal structure (casing) mounted under the vehicle which contains and protects the platform carriage assembly. The housing contains all lift components
except the power (pump) module when the lift is in the stowed position.
Platform Carriage Assembly: The platform carriage assembly includes the platform assembly, the lifting arms, the rolling hori- zontal arms that carry the plat- form assembly in and out of the housing and the electrical/ hydraulic drive components that power the lift.
Platform Assembly: The lift platform assembly consists of the flat aluminum plate with raised diamond embossing upon which the wheelchair is positioned, the outboard roll stop, the inboard roll stop (if so equipped) and optional handrails (if so equipped).
Outboard Roll Stop: The outboard roll stop is the automatic electric
Bridge Plate (Inboard Roll Stop): UVL lift models are equipped with an automatic or manually operated bridge plate (except model UVL603A). The bridge plate bridges the gap between the lift platform and the vehicle floor. Bridge plates also serve as inboard roll stops.
Automatic bridge plates are fully- automatic in operation and are activated by the lift control switches (no attendant required). Manual bridge plates must be operated by an attendant. Fur- ther details and instructions for operation of manual bridge plates are provided on page 12 of this manual.
Platform
Lift Actions and Functions:
Extend: Extend is the action of the platfom carriage assembly moving (rolling) out of the lift housing.
Retract: Retract is the action of the platfom carriage assembly moving (rolling) into the lift housing.
Deploy: Lift deployment is the action of the lift platform carriage assembly extending (moving outward) from the housing and lowering to ground level when the
DOWN switch is activated or raising to floor level when the UP switch is activated.
Stow: Stow is the action of the lift platform carriage assembly retracting (moving inward) into the carriage assembly housing. During the stow function, the platform will automatically raise or lower to stow level before retract- ing into the housing.
Stow Level: Stow level is the height that the platfom carriage
assembly moves in and moves out of the lift housing.
Floor Level: Floor level is the height that the platfom carriage assembly raises to in order for the wheelchair passenger to enter and exit the vehicle.
Note: Further details regarding lift control switches and the corresponding lift functions are provided in the Lift Operating Instructions on pages 10 and 11.
