transit vehicles. The RA300
provides vehicle access to people
with disabilities (wheelchair pas-
sengers or standees using other
type mobility aids). The commer-
cial oriented ramp is ADA compli-
ant (dependant upon installation
height). See the Installation sec-

The self-contained “drop-in” unit
requires no remote pump, exter-
nal hydraulic lines or pre assem-
bly. The hydraulic and electrical
components are internal and eas-
ily accessible. A single electrical
feed provides the power supply
(12 volt or 24 volt), the ground, a
ramp OUT signal (+), a ramp IN
signal (+) and various indicator
signals.
The RA300 features a 32” wide
ramp in a 34” wide package. A

signed to be operated by an
attendant. The ramp installer
provides an appropriate control
switch for the end user. Con-
squently, the operating instruc-
tions contained in this manual
are generic due to the limitless
variables.
The RA300 provides fully auto-
matic operation of ramp functions.
The electric/hydraulic system is
controlled by two relays which ac-
tivate the hydraulic pump in oppo-
site directions for deploy and stow
functions (powering a dual-acting
hydraulic cylinder). No sensitive
electronic controls or sensors are
required for operation.
All RA300 ramp models feature
gravity down "drift" during the
deploy cycle. When deploying
the ramp, the motor stops running
when the ramp reaches an ap-
proximate 45° angle. The ramp
continues to slowly lower the
remaining distance by the force of
gravity.

"Y" are hydraulic fold with gravity
down "drift" feature when deploy-
ing and stowing. When stowing
the ramp and it folds inward be-
yond the 15° shut off point, gravity
lowers the ramp to the pan.

throughout the stow cycle (to full
stow). The hydraulic system re-
mains pressurized while the ramp
is in the stowed position.
The pressure relief valves built
into the pump prohibit the ramp
from lifting (raising) with approxi-
mately 20 pounds or more on the
ramp.
Instructions are provided for
manual operation of the ramp
in event of power or equipment
failure. See Manual Override
on the following page for further
details.
Read and become familiar with
all operation safety precautions,
pre-operation notes and details,
operating instructions and manual
operating instructions before at-
tempting operation.
