11.4 Hydraulic equipment (HY)
The hydraulic equipment includes the hydraulic motor for the main motorization, mounted in
correspondence of the central axle of the winch.
The hydraulic motor needs to be connected to a hydraulic circuit by two high pressure tubes
that are used for inlet and outlet, according to the direction in which the motor is running.
Motor also requires a third connection with a low-pressure tube for drainage, so that excess
oil can return to the system reservoir so as to avoid shortening the life of the motor.
The role of the motor is to make the drum revolve in two directions (clockwise for a right-
hand winch and anticlockwise for a left-hand winch), so as to allow the winch to operate at
the three speeds for which it was designed.
Hydraulically operated winches have a load capacity proportional to the working pressure of
the system, while the recovery speed of the winch is proportional to the oil flow.
The displacement values of the hydraulic vertical versions of the Winch 1130 are: 80cc,
100cc, 116cc, 160cc, 200cc and 211cc.
