Torque Converter & Shuttle Gearbox
The dumpers are either fitted with a Spicer Compact Plus
Powershift Reversing Shuttle or an ITL PowerShuttle gearbox
with integral 4 speed synchronised transmission and a Borg
Warner Torque Converter.
The procedure for driving the vehicle is as follows:-
z Select Forward / Reverse using the Direction Switch.
z Depress the Gearlever Drive Interrupt Button (A) on the
gearlever and hold whilst moving into first gear. This button
is the equivalent of a clutch pedal on a conventional dumper.
z Release the button (A) and gearlever.
z Release the handbrake.
z Press the accelerator pedal down slowly, drive will be
progressively taken up through the torque converter and the
dumper will move off.
Changing gear, up or down the range, is effected by depressing
the electric drive interrupt button (A) on the gearlever and moving
the gearlever into a higher or lower gear position.
Descending Gradients
The operator must select a suitable low gear for descending the
gradient. If the operator is in any doubt as to the gear to be
selected, first gear must be selected.
Stopping and Moving off on a gradient steeper than the
handbrake capability
Stop the vehicle on the footbrake, continue to apply the footbrake
and apply the handbrake, and select neutral on the forward
reverse lever. To move off select 1st gear then forward/reverse,
hold the vehicle on the handbrake, release the footbrake and
apply the throttle to drive against the handbrake. When the
vehicle starts to move in the desired direction release the
handbrake and move off.
Emergency Stopping on Slopes - (Running Out of Fuel)
Where possible park the machine at a slight angle across the slope
(less than 8.5º (15%), chock the wheels and refuel. If near the
bottom of the gradient the vehicle can be allowed to roll backwards
to the bottom of the gradient, however caution must be exercised
as the vehicle has no engine braking, and heavy steering.
See Gradient section in this manual for further information.
ENSURE THE MACHINE IS AT REST BEFORE MOVING THE
