Abstract: A supporting belt for a transport device, such as an elevator system, includes at least one stranded wire made of an electrically conducting material for absorbing the forces absorbed by the supporting belt and an electrically insulating jacket that encloses the wire. In order to determine the state of the wire, the wire can be contacted by a contact element securely and reliably and in an exact manner. To achieve this, the jacket is at least partially removed in the area of an opening of the supporting belt and the wire is at least partially exposed in the area of the opening. The wire thus does not include a jacket substantially perpendicularly to a longitudinal axis formed by a center point of a cross-section of the wire. The wire can be contacted by a contact element without the jacket being pierced.

The braking equipment includes at least two brake units, at least one of the brake units, but preferably each of the brake units, is provided with a wear-compensating device which, when the brake unit is opened or released, sets a clearance distance between a brake lining and an associated brake surface, which clearance arises on opening of the brake unit, in correspondence with a substantially constant value. Thereby, use may be made of customary and thus economic brake materials which may wear during braking.
