System Description
2-6
Hoist Control Lever Handle
A modified hoist lever handle replaced the
existing handle to provide a midpoint override
switch
capable of disabling the ECM
commanded hoist raise stop signal. The hoist
lever still performs normal hoist functions of
RAISE, HOLD, FLOAT and LOWER as
described in the CAT Operators Safety Manual
with the exception of hoist raise automatic
midpoint stop feature as described below and in
the Body Assembly ECM. The hoist lever will
also
allow tailgate functions to occur
automatically at the beginning of a raise
function (tailgate down to unrestrain container
doors) and at the end of a body lower function
(tailgate up to retain container doors) only when
the vehicle is in forward motion above 7 mph.
Tailgate Remote Operation Switches
The panel is mounted on the left rear tube of the
body assembly just below the amber marker
light. The panel contains 2 switches normally
used to lower the tailgate and relieve pressure
on the container doors or to raise the stinger to
secure the tailgate for transport. These switches
will only function if the stinger fault indicator
lamp is extinguished, the hoist lever is in
FLOAT, twistlocks are in the full ENGAGED
position and the vehicle is stationary.
The OPEN switches may also be used for
limited body lift function. This function is
limited by the additional ECM as programmed.
This will prevent the body from raising above
the preset angle when the stinger OPEN switch
is depressed. If the body does RAISE the ECM
will command the hoist valve to return to the
FLOAT position and the body will lower.
