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.
Claims12
A load carrying means for cable elevators with integrated load measuring equipment, in which the weight force of the load carrying means and a useful load causes a load-proportional deformation of at least one resilient element, wherein at least one sensor detects this deformation and produces, as an input for an elevator control, a signal representing the amount of the deformation and thus the load, comprising:
- a support construction adapted to be attached to an underside of an elevator car;
- a pair of cable rollers positioned below said support construction;
- and
- a resilient element attaching at least one of said cable rollers to said support construction whereby when said support construction is attached to the underside of the elevator car and said cable rollers are engaged by a support cable supporting the elevator car, said resilient element is deformed by load-dependent cable forces acting on said resilient element through said at least one cable roller.
