AUTOMATIC winch concept

■ Description of the AUTOMATIC winch
■ The AUTOMATIC winch is an attachment for the BISON snow groomer. It has its own removable
support structure which is mounted on the vehicle frame at four fastening points. The AUTOMAT-
IC winch can considerably increase the snow groomer's climbing ability and snow moving power.
It enables the snow groomer to prepare ski slopes even on extremely difficult slopes.
A work lamp is attached to the winch arm and a work lamp illuminates the cable magazine. The
work lights are automatically switched on when the winch is in operation.
Drum with cable magazine
■ The cable drum with cable magazine is powered by a hydraulic motor and a planetary gear sys-
tem. The hydraulic cable winder ensures that the cable is wound correctly and uniformly onto the
drum.
Pivoting winch arm
■ The winch arm is mounted on the AUTOMATIC winch frame and is fitted with three guide pulleys.
It allows the snow groomer to move in any direction within a 360° swivel range. From the driver's
cab, the winch boom can be swivelled hydraulically into the desired direction, so that the cable
can be anchored more easily. When the AUTOMATIC winch is stopped, the winch arm is locked
by a spring-load multidisc brake.
Brake
■ The AUTOMATIC winch is fitted with a spring-loaded multi-disc brake.
