METHOD FOR INFLUENCING A CABLE WINCH FORCE ACTING ON A CABLE DRIVE AND DEVICE FOR CARRYING OUT A METHOD OF THIS TYPE

摘要

A method for influencing a cable winch force acting on a cable drive, comprises the method steps providing a cable drive with a drivable winch and with a cable that can be wound on the winch, providing a device for producing a traction sheave cable force on the cable, determining an outer cable force, predetermining a cable drive operating state, providing a control-regulating unit to influence the traction sheave cable force, producing a control-regulating variable by means of the control-regulating unit depending on the outer cable force and the predetermined cable drive operating state, producing the traction sheave cable force by means of the device and influencing the traction sheave cable force by means of the control-regulating unit in such a way that the cable winch force acting on the cable drive can be controlled depending on the respective cable drive operating state and the outer cable force, wherein the device is a traction sheave drive, wherein a four-quadrant operation of the traction sheave drive is reproduced by means of the control-regulating unit, and wherein the four traction sheave drive operating states are no-load lifting, no-load lowering, load lifting and load lowering.
