Operation & Control (See Fig 1-12, 1-13)
The H5C winch is designed to operate with a pilot oper-
ated hydraulic system. Hydraulic tractor power supplies
include variable displacement with load sensing control,
fi xed displacement, and variable displacement hydrostatic.
When the tractor is running, the winch is ready to operate
but no oil is fl owing to the winch. Control (pilot) pressure is
present at the winch.
The control lever and electrical switches are used to select
the following operations (not all winches are equipped with
all options):
BRAKE-ON
(spring-centered position)
LINE-IN
LINE-OUT
FREESPOOL
HI-SPEED
(either
LINE-IN
or
LINE-OUT
) (optional)
DRAG-BRAKE
(optional)
The tractor must be running and the auxiliary hydraulic func-
tion switch, if equipped, must be on.
LINE-IN
,
LINE-OUT
and
BRAKE-ON
are controlled by a control lever.
When the control lever is in the
BRAKE-ON
or centered
position, the holding brake is automatically applied. Push-
ing the lever away from the operator releases the brake
and reels cable off the drum (
LINE-OUT
). Pulling the lever
towards the operator releases the brake and reels wire rope
onto the drum (
LINE-IN
). Releasing the lever causes it to
return to the
BRAKE-ON
position, which stops the drum
rotation and applies the holding brake. By moving the lever
a small amount, slow wire rope movement is achieved for
inching control. Line speed increases proportionally as the
lever is moved farther.
The switch panel may contain three rocker switches that
control
FREESPOOL
,
HI-SPEED
and
DRAG-BRAKE
.
The tractor must be running to supply hydraulic power to
operate these functions. The switch light illuminates when
the switch is on.
The
FREESPOOL
switch has a lock to prevent inadvertent
actuation. The slide lock must be released before the switch
can be turned on.
Before operating the winch in LINE-IN or LINE-
OUT mode, ensure the FREESPOOL and DRAG-
BRAKE lights are not illuminated. Doing so may
result in loss of load.
HI-SPEED
is selected with a dual-action momentary switch.
A green light in the speed selector switch indicates
HI-
SPEED
operation. For heavy loads or when better control
is desired, the winch should be operated in low speed. For
light loads and faster wire rope speed, operate the winch
in
HI-SPEED
mode.
When the
DRAG-BRAKE
(optional) switch is selected,
FREESPOOL
is engaged, and a drag brake is engaged
on the drum shaft, allowing the tractor to move slowly away
from a towed load while keeping the wire rope taut. The
tractor must be operated at low speed or the load may
still be dragged.
