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 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.
