Method for operating a winch of a tracked vehicle and snow groomer

摘要

The method involves detecting the speed of chain (4) and rope. The angle of winch arm (3) is detected along the longitudinal axis of vehicle (1). The running speed of vehicle is determined, based on the rope speed and the angle of winch arm. The cable force is detected, by comparing the chain speed and the running speed of vehicle. A target value is determined for power cable, based on the difference between the chain speed and running speed of vehicle. An independent claim is included for runway crawler-type vehicle.
