Abstract
A load carrying and measuring apparatus for cable elevators includes a support construction attached to an underside of a base frame or a carrier frame for an elevator car and a pair of cable rollers attached below the support construction for engaging a support cable. A resilient element attaches at least one of the cable rollers to the support construction whereby the resilient element is deformed by load-dependent cable forces acting through the cable roller. A sensor detects the deformation of the resilient element and sends a signal to the elevator control. A resilient isolating element can be connected between the support construction the base frame or the carrier frame.
