Ramp Components
Refer to the Terminology Illustra-
tions on pages 2 and 3.
Pan Weldment (Housing):
The pan is the stainless steel
(casing) mounted in the vehicle
ÁRRUV\VWHPZKLFKFRQWDLQVWKH
hydraulic pump and electrical
components that power the ramp
electric/hydraulic systems. The

components from above. The
cover is easily removed for ac-
cess to drive components. The

surface for entry and exit when
the ramp is deployed. The
RA300 stows (folds) onto the sub
ÁRRUSURYLGLQJDQXQREVWUXFWHG
antiskid surface for entry and exit
when the ramp is not in use.
Ramp Assembly: The ramp
assembly is made of an inboard
ramp section (stage one) and an
outboard ramp section (stage
two). Each aluminum ramp sec-
tion features vertical side plates
and full antiskid surface.
Drive Arm Assembly:
The cylinder driven two stage
drive arm assemblies deploy and
stow the ramp assembly.
Ramp Actions and Functions
Deploy: Deploy is the action
of the ramp assembly extend-
ing and unfolding to ground
level when the DEPLOY (OUT)
switch* is activated (*installer
supplied).
Stow: Stow is the action of the
ramp assembly raising and fold-
ing inward to stow position when
the STOW (IN) switch* is acti-
vated (*installer supplied).
Stow Position: Stow position
is achieved when the two stage
ramp assembly is fully retracted
and folded (resting fully on the
pan weldment).
Manual Override: A cable-acti-
vated manual release engages
and disengages the hydraulic
system. A T-handle is provided
for activation of the manual
release. Pulling the T-handle out
pushes a pump valve to release
pressure (turn T-handle to lock in
released position). Disengaging
the hydraulic system allows the
ramp to be manually deployed
and stowed (hydraulic pressure
released). See Ramp Manual
Operation on page 11 for further
details.
