ABSTRACT:
An apparatus for maintaining tension on a tension cable which is wound on the drum of a winch and connected at one end to a position varying object, especially for maintaining the tension of a power cable leading to a travelling coal extraction machine. The winch, preferably a conventional pressure drive operated hauling coiler can be regulated and driven reversibly and it can produce also at stand-still a continuous rotary moment. A tensioning device having a tensioning pulley 11 is also provided and is subjected to the force of the spring 14, the tension cable 6 being guided around the pulley 11 so that over the spring force a desired nominal tension can be set on the tension cable. Position changes of the tension pulley produce over an actuating linkage 14 a control of the winch so that the tension pulley returns into the original equilibrium position. This control process may be accompanied by running the cable off the winch or hauling it in. Instead of the tension pulley 11 the tension device can comprise also another movable element for example the drum 9a of the winch 9 when the winch is to be guided movably as a whole against the spring force.
