Abstract
The invention relates to a traction device (), especially for an elevator system. The traction device () is driveable by a traction sheave. The task which is the basis of the invention is to provide a traction device which is simple to manipulate. High tension forces are transferable and the traction device makes possible a drive unit of lesser width compared to the known belt technology. For this purpose, the traction device is configured as a composite rope () wherein individual tension carriers () are connected to each other via a one-sided elastomer connecting layer (). The individual tension carriers () lie in parallel and are jacketed with elastomeric material. The tension carriers () engage in corresponding grooves () of the traction sheave (). The tension carriers () engage in the grooves () of the traction sheave () with at least 25% of their total diameter.
