3-13.2
The
WINCH CLUTCH HANDLE (See
is located on the right
or curb-side end of the winch assembly. The
function of the Winch clutch handle is to en-
gage or disengage the winch, allowing it to
respond to the Winch Hydraulic lever.
CAUTION
A MINIMUM OF 5 WRAPS OF CABLE
MUST BE LEFT ON THE WINCH DRUM.
a.
The
12,000 lb. WINCH CLUTCH HANDLE
has two positions:
(See Figure 3-6)
DISENGAGE
When the handle is placed is this
position, the winch is disengaged.
This allows the spool to “free-wheel”
and the winch is not affected by use
of the Winch Hydraulic lever.
ENGAGE
When the handle is placed in this
position, the winch is engaged and
cable may be spooled on or off the
winch spool. The winch can now be
controlled through the use of the
Winch Hydraulic lever.
b.
The
20,000 lb WINCH CLUTCH HANDLE
has two positions. (See Figure 3-7).
DISENGAGE
When the handle is placed in this
position, the winch is disengaged.
This allows the spool to “free-wheel”
and the winch is not affected by use
of the Winch In/Out lever.
LEFT
When the handle is placed in this
position, the winch is engaged and
cable may be spooled on or off the
winch spool. The winch can now be
controlled through the use of the
Winch In/Out lever.
c.
If your semitrailer is equipped with two
winches, the upper deck winch is normally
operated with the first lever of an additional
three spool valve mounted to the left of the
first three spool valve. Winch operation is the
same as described in
Section 3-13.
d.
Instead of an additional three spool valve, a
WINCH SELECTOR VALVE CONTROL (See
Figure 3-8)
may be used to operate two
winches, one at a time. The winch selector
valve control is located just to the left of the
standard controls. It has two positions:
PUSH
When this control is pushed in, the
lower deck winch is activated.
PULL
When this control is pulled out, the
upper deck winch is activated.
e.
Once the winch is selected, winch operation
is the same as described in
Section 3-13.
IMPORTANT
ELECTRIC REMOTE OPERATION IS DE-
SCRIBED IN SECTION 3-14.
