Inching is used for fi ne control of the winch speed. When
the control lever is slowly moved to a position between
BRAKE-ON and LINE-IN or between BRAKE-ON and
LINE-OUT , inching occurs. Any adjustments require
computer program changes and may be necessary
for some customer operations. Contact Allied Systems
Company if inching needs adjustment. The following
paragraphs describe the normal procedures for inching.
CAUTION
Excessive inching will accelerate clutch and
brake wear, and cause winch overheating.
Inching (LINE-OUT) . This operation will release the
brake before the reverse clutch is applied. This permits the
weight of the load, with assistance from the reverse clutch,
to unwind wire rope from the winch drum against the
resistance of the brake. The reverse clutch is completely
applied when the operator moves the control lever into
the
LINE-OUT position. When the control lever is moved
so that the reverse clutch is engaged, the speed that the
drum unwinds is controlled by the rpm of the tractor PTO.
Inching (LINE-IN) . This operation is used to slowly move
a load toward the tractor. The control valve will cause the
oil pressure to slowly release the brake and slowly apply
the forward clutch. As the brake is released, the clutch
takes control and begins to move the load.
