<p>The invention belongs to the field of forest winches, more precisely, to the filed of devices for winding and unwinding of a wire rope and enabling a reliable stoppage. The essence of the device for controlled winding and unwinding of a wire rope/a spun wire cable via a pulley is in that a sensor for monitoring the position of an end-piece/ending or adjustable stop/washer of the pulling end of the wire rope enables the switch-off of the winch in the case when the pulling end of the wire rope approaches a rope guiding mouth for a certain distance. The spatial or three-dimensional adaptation of the rope wire travel over the pulley and the sheave into the mouth and the end-piece is controlled by a swinging carrier of guiding/compression sheaves which are pressed by two springs adjustable by means of two bolts of the swinging carrier. Beside a hydraulic motor, the hydraulic drive features a damper valve and a non-return valve placed on a return flow pipe of the hydraulic motor.</p> |
