Hydraulic motor
1
. A hydraulic motor provided with multiple wet brake,
which converts the pressurized oil delivered from
the motor into the turning force.
2. When a winch lever is operated, this motor
releases the brake by the pressurized oil delivered
from the hydraulic valve, as well as transmits the
turning force.
3. The motor power is transmitted to the winch drum.
While the rotating speed is reduced and torque is
increased with by the spur gear reduction device.

.2 Counterbalance valve
1
. This valve gives back pressure to the return circuit
in order to prevent abrupt load falling or motor
rotation and ensure the hoist-down speed
corresponding to the oil rate delivered from the
hydraulic motor.
2. When high hold pressure is generated between
the winch motor and the counterbalance valve
due to quick switching of the winch operation
selector valve, the overload relief valve opens to
let the pressure escape to the tank in order to
prevent damage.
1
.3 Hydraulic valve
1
. Selects applying or releasing of the automatic
brake for the main and aux. winch. When the
winch lever is operated to hoist up or down,
pressure created by this operation shifts the valve.
Consequently, the pressurized oil from the
accumulator flows into the automatic brake
cylinder, presses the spring and releases the
brake, allowing the drum to rotate.
2. When the winch lever is returned to neutral, the
valve is spring-returned to the neutral position as
the pilot pressure decreases, and the oil in the
winch brake cylinder flows to the tank.
Consequently the brake is applied by the spring.
1
.4 Solenoid valve (telescoping/aux. hoist)
1
. Delivers the pilot pressure from the remote control
valve to either the block of the boom telescoping
side or auxiliary winch operation side of the
hydraulic pilot control valve when the
telescoping/aux. winch operation selector switch
is shifted to "Telescoping".
