Introduction
Braun RA300 Series transit
ramps are designed for use in
ORZÁRRUWUDQVLWYHKLFOHV7KH
RA300 provides vehicle ac-
cess to wheelchair passengers
or standees using other type
mobility aids. The commercial
oriented ramp is ADA compliant
(dependant upon installation
height). See the Installation
VHFWLRQIRU$'$VSHFLÀFDWLRQV
The self-contained “drop-in”
unit requires no remote pump,
external hydraulic lines or pre
assembly. The hydraulic and
electrical components are
internal and easily accessible.
A single electrical feed provides
the power supply (12 volt), the
ground, a ramp deploy signal
(+), a ramp stow signal (+) and
various indicator signals.

designed to be operated by an
attendant. The installer provides
an appropriate control switch for
the end user. Consequently, the
operating instructions contained
in this manual are generic due to
the limitless variables.
The RA300 provides fully
automatic operation of ramp
functions. The electric/hy-
draulic system is controlled by
two relays which activate the
hydraulic pump in opposite
directions for deploy and stow
functions (powering dual-acting
hydraulic cylinders). No sensi-
tive electronic controls or sen-
sors are required for operation.

when deploying and stowing.
When deploying the ramp, the
motor stops running when the
ramp reaches an approximate
45° angle. The ramp continues
to slowly lower the remaining
distance by the force of gravity.
When stowing the ramp and
it folds inward beyond the 15°
shut off point, gravity lowers
the ramp to the pan.
The pressure relief valves built
into the pump prohibit the ramp
from lifting (raising) with ap-
proximately 40 pounds or more
on the ramp.
Instructions are provided for
manual operation of the ramp.
See Manual Operation on the fol-
lowing page for further details.
Read and become familiar with
all operation safety precautions,
operation notes and details, op-
erating instructions and manual
operating instructions
before
attempting operation.
