ABSTRACT:
A continuous winch with two, drums at least one of which is driven and is provided with a multiple groove configuration with one discharge groove for the non-loaded cable. The non-loaded, running-off, or discharging cable in the discharge groove is capable of being stressed or tensioned transverse to the discharge direction. The discharge groove is limited by a tensioning disc which is spring-loaded in the tensioning direction. The tensioning disc is capable of being lifted from the cable counter to spring-loading by a hydraulically engaged stroke piston. The cable exit groove, which is located opposite the discharge groove in the axial direction of the drums, is limited by a clamping disc, which is capable of being tensioned by a hydraulic pressure piston against the cable. The stroke piston of the tensioning disc, and the pressure piston of the clamping disc, are coupled by a hydraulic control and are capable of being engaged by pressure in opposite directions with respect to the cable.
