A38E PURPOSE & LIMITATIONS
NOTE: It should be recognised that if the tilt
switch senses a degree of slope greater than
3º the elevating circuits will lockout and
sound a warning alarm. The Emergency
Override should then be used, to lower the
Elevating Assembly.
DRIVE & STEER SYSTEMS
The A38E Work Platform is restricted to low speed
drive when the Platform is raised above the Boom
Rest Limit Switch. The Traction controller controls the
application of drive from the Joystick by means of two
Traction Motors, which are assembled to the drive
wheels via a Drive Reduction Gearbox.
POWER SYSTEM
The power system incorporates eight 6V batteries
driving the drive traction motors, or the 4kW (5.4HP)
electric motor which in turn drives the hydraulic
pump. The application of this hydraulic pressure is
performed by the Control System.
CONTROL SYSTEM
The machine is provided with fully proportional
controls by means of the interaction between a
P600, electron tor o m c i contro l a d n a r e l proportional
joystick. The P600 and motor controller regulate the
drive motor/pump speed and hence the flow of oil
reaching the cylinders, the Worm Drive Unit or the
Drive Reduction Gearbox. It regulates the direction of
flow of the hydraulic oil via the solenoid valves located
on the manifold block, and it also monitors the opera-
tion of all switches on the machine via the machine
harness system.
The motor control units are located, in the left hand
chassis module. The manifold block is located on the
hydraulic tank. This is accessible by removing the
main cover.
CHASSIS
The chassis is a structural frame designed to support
all the components of the A38E Work Platform.
DANGER
Steering of the A38E Work Platform is controlled by
a double acting cylinder. An Operator can Steer left
or right by depressing the Rocker Switches on top of
the Joystick, while activating the Interlock Switch.
The purpose of the A38E work platform is to provide a
quickly deployable variable height work platform. It is
capable of lifting a specified number of people with work
tools up to an upper limit of 215 kg (ANSI 475 lbs) in
total. The unit will provide the ability to reach over
obstacles but must be used on firm level ground.
See Specification table on page 1-3.
The platform must only be used on firm level or slightly
uneven ground capable of supporting the maximum load
generated under the four wheels. Do not use on soft or
severely sloping ground.
