DRIVING ARRANGEMENT FOR A CABLE PASSED ABOUT A DRIVEN GUIDE ROLLER

摘要

A cable is trained around a reversing sheave that is adapted to be driven and is preferably pulled relative to a trolley, which is movable on wheels along a track cable by traction exerted by a traction cable and a return cable. The cable is adapted to be found against the drivable reversing sheave by means of an endless flexible tensile element, which is trained around part of the drivable reversing sheave together with the cable and is trained around at least one additional reversing sheave and consists, e.g., of a belt or a sidebar chain.
