RAMP TERMINOLOGY
Introduction
The Braun RA300 Transit Ramp
(to be referred to as RA300
throughout this manual) is de-
vehicles. The RA300 provides
vehicle access to people with
disabilities (wheelchair passen-
gers or standees using other type
mobility aids). The commercial
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 (+) and a ramp
IN signal (+).
The RA300 features a 32" wide
ramp in a 34" wide package. A

signed to be operated by an at-
tendant. The ramp installer

provides an appropriate control
switch for the end user. Conse-
quently, 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.
The gravity down "drift" feature
enhances safety and prevents
vehicle and/or ramp damage.
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.
Similarly, 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 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 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.
