Figure 1-11 Winch Controls
Operation & Control (See Fig. 1-11)
The H6G winch is designed to operate on a load sense, pilot
operated hydraulic system. 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
• BRAKE-OFF (optional)
• FREESPOOL
• HI-SPEED (either LINE-IN or LINE-OUT) (optional)
The tractor must be running and the auxiliary hydraulic
function switch, if equipped, must be on. LINE-IN, LINE-
OUT and BRAKE-ON are controlled by a proportional
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 wire rope 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. Moving the
lever a small amount results in slow wire rope movement
for inching control. Line speed increases proportionally as
the lever is moved farther.
The switch panel may contain three rocker switches to
control FREESPOOL, BRAKE-OFF and HI-SPEED. Not
every winch is equipped with all three. The tractor must be
running to supply hydraulic power to operate these func-
tions. A light shows when a switch is on.
The FREESPOOL and BRAKE-OFF switches incorporate
a lock to prevent inadvertent actuation. The slide lock must
be released before the switch can be turned on. When
the BRAKE-OFF switch is selected, the holding brake is
released, allowing the tractor to move slowly away from
a towed load. The tractor must be operated at low speed
or the load may still be dragged.
Before operating the winch in LINE-IN or
LINE-OUT mode, ensure the FREESPOOL and
BRAKE-OFF lights are not illuminated. The
winch will not operate.
The HI-SPEED switch is a dual-action momentary switch.
Pushing it towards the operator allows the winch to oper-
ate at low speed, while pushing the switch away from the
operator activates HI-SPEED. When in HI-SPEED mode,
the winch will automatically shift to low speed when the load
exceeds a certain percentage of the rated load. For heavy
loads or when better control is desired, the winch should
be operated in the normal speed. For light loads and faster
wire rope speed, operate the winch in HI-SPEED mode.
The green light in the speed selector switch indicates HI-
SPEED operation.
