It will be noticed that on the Upper Control Box a set
of switches are used to alternate functions. Each
function will have it’s corresponding graphicand lamp.
This selector switch indicates to the Controller which
function is required and by using the Joystick the
speed of this selected function can be adjusted.
The boom functions on the chassis controls provide
proportional control for each function by way of an
analog rocker switch, the desired function can be
activated by holding on one of four switches on the
controls and and operating the analog rocker, the
The use of these functions is further explained
throughout this Section.
DESIGN FEATURES
The A38E Series Work Platform has the following
features:
The drive speed is limited to a ‘creep speed’ when
operating the Work Platform while the machine is
elevated.
The energy-efficient motor control units provides
long battery life and smooth proportional control of
the boom and drive functions.
All cylinders are fitted with hydraulic hose-burst
protection interlocks.
The on-board charger is fully automatic and
charges the batteries efficiently and economically.
If the work platform starts to become unstable and
the Tilt Sensor is activated an alarm will sound in
the upper control box. In this situation power is
partially cut to the upper controls to prevent any
boom movements (i.e. UP, TELE OUT) that might
increase instability. An emergency override switch
is fitted to allow the booms to be lowered at a
controlled speed to bring the machine back to a
stable position.
In the event of a power loss the two Boom Lift
Cylinders are fitted with emergency lowering
valves which allow the booms to be lowered at a
controlled speed by an operator on the ground.
A Master Cylinder/Slave Cylinder levelling system
ensures that the Platform remains level throughout
the entire working cycle of the machine.
A manual rotation facility is fitted to allow rotation of
the Elevating Assembly in the event of power loss.
the four switchs act as both selector & enable
switches.
