Freely revolving rollers for cables and for cables with crane snatch blocks

摘要

The cable(112) moves with rolling contact on a stationary component(102) by means of revolving rollers(104,105) which are guided and/or retained by a guide element(113) and/or housing components(111) and/or connecting plates. The rollers describe a spatial curve and are fed back on a short path in the section not enwrapped by the cable. The stationary component is rigidly connected to other structural components, and/or forms a unit with these.
