Abstract
A force transmission or transport device having a line of force transmitting elements (2), a guide (1) for guiding the line of force transmitting elements (2) along a predetermined course, and at least one drive. A tensioning drive (6) is provided at one end of a section (5) of the predetermined course. A further drive (3), or an intermitting stop (9), is provided at the other end of the section (5) for tensioning the line of force transmitting elements (2) by a tractive or a compressive load. The further drive (3) or stop (9) acts substantially without slippage on the force transmitting elements (2). The tensioning drive (6), via a friction clutch, starts slipping when the desired tension has built up.
