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
floor system which contains the
hydraulic pump and electrical
components that power the ramp
electric/hydraulic systems. The
fixed sub-floor cover protects the
Ramp Actions and Functions
Deploy: Deploy is the action of
the ramp assembly raising and
unfolding (rotating) 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 (rotating) inward to stow posi-
tion (floor level) when the STOW
(IN) switch* is activated (*installer
supplied).
components from above. The
cover is easily removed for ac-
cess to drive components. The
sub-floor provides an antiskid
surface for entry and exit when
the ramp is deployed. The
RA400 stows (folds) onto the sub
floor providing an unobstructed
antiskid surface for entry and exit
when the ramp is not in use.
Stow Position: Stow position
is achieved when the ramp as-
sembly is resting fully on the pan
weldment (rotated inward and
lowered fully).
Manual Override: Manual
operation is achieved without the
use of any mechanical release or
complicated procedures. Simply
manually deploy or stow the ramp
assembly. A strap is provided on
the ramp to manual deploy the
RAMP TERMINOLOGY
Ramp Assembly: The ramp as-
sembly is made of an aluminum
ramp section. The ramp features
vertical side plates and full anti-
skid surface.
Drive Arm Assembly: The
cylinder driven drive arm assem-
blies deploy and stow the ramp
assembly.
ramp from the stowed position.
Minimal physical effort is required
to route the hydraulic fluid through
the system. Slow steady motion
results in the least resistance and
easy operation. The faster you
attempt to manually operate the
ramp, the greater the resistance.
See Ramp Manual Operation on
page 11 for further details.
