Lift Terminology
pump module consists of the
hydraulic pump, the manual hand
pump and electrical components
that power the lift electric/hydrau-
lic systems.
Module-mounted Control
Switches: The pump module is
equipped with three color-coded
and function-labeled control
switches (OPEN/CLOSE, IN/OUT
and UP/DOWN). The switches
activate the automatic lift func-
tions and optional door operators.
Further details are provided in the
Lift Pre-Lift Operation section
(page 13).
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.
