Abstract
A force transmission or transport device having a line of force transmitting elements (,), a guide (,) for guiding the line of force transmitting elements (,) along a predetermined course, and at least one drive. A tensioning drive (,) is provided at one end of a section (,) of the predetermined course. A further drive (,), or an intermitting stop (,), is provided at the other end of the section (,) for tensioning the line of force transmitting elements (,) by a tractive or a compressive load. The further drive (,) or stop (,) acts substantially without slippage on the force transmitting elements (,). The tensioning drive (,), via a friction clutch, starts slipping when the desired tension has built up.
