Disabled Passenger Lift DPT-512 | 16
SECTION 1 | GENERAL INFORMATION & OPERATING PROCEDURES
1.1.5 | Front Platform
The front platform extends 24” (610 mm) out from the van body on steel
rollers, and serves as a forward extension of the van body to bridge the gap
between the van body floor and the door threshold of the aircraft being
serviced. The platform is attached to the forward end of the van body by
a system of rollers that run in vertical tracks welded to the front of the van
body. The platform rests on the screen guard when the van body is lowered.
When the van body is raised, the platform continues to rest on the screen
guard until the van floor and the platform are even. Beyond this point,
stops in the bottom of the vertical tracks on the van body lift the platform
to the same height as the body floor. The front part of the platform can be
extended and retracted electrically using a control switch in the van body
control station. The platform has telescoping side rails with rubber bumpers
on the extended railings and a full-width rubber bumper at the front of
the platform. The railings on the sides of the platform are painted in safety
yellow. The floor is constructed from diamond plate flooring.
1.1.6 | Screen Guard
The screen guard behind the truck provides support for the front platform
to rest on when the platform is fully down.
1.1.7 | Power Lift Gate
The power lift gate is attached to the platform at the rear of the van body.
Its purpose is to move passengers and equipment between ground level
and the van body floor. The lift gate has a rated capacity of 2000 pounds
(908 kg). It has its own hydraulic system that is separate from the primary
hydraulic system. The emergency operating system has a hand pump used
for raising the lift gate, two valves to fold/unfold the lift gate, and a valve to
lower the lift gate.

DESCRIPTION
Lift Gate Platform
This is a 85 x 55 inch (2159 x 1397 mm)
aluminum platform with 42” (1067 mm) high
folding railings that moves between ground
level and the van body floor level. When not in
use it can be pivoted upwards and stowed in
place.
Lift Gate Power System
The lift gate has its own hydraulic system,
driven by a 12 VDC motor that is powered
by the truck's electrical system. It is self-
contained, with its own pump, reservoir,
hydraulic cylinder, and electrical switches.
This system is built into the lift gate structure.
