A wire rope clamp assembly for use with an elevator is provided. The wire rope clamp includes a first clamp member having an outer side and an inner side. The inner side has a plurality of channels configured to receive one or more suspension members. The plurality of first clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. A second clamp member is configured for attachment to the first clamp member. The second clamp member has an outer side and an inner side. The inner side has a plurality of channels configured to receive the one or more suspension members. The plurality of second clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. The plurality of surface structures for the first and second clamp member channels are multidirectional.

An elevator system has an elevator shaft, an elevator car and a drive device for displacing the elevator car within the elevator shaft. The drive device is a linear motor that has a stationary part secured to a shaft wall of the elevator shaft and a movable part secured to the elevator car. The drive device has an air bearing between the stationary part and the movable part that keeps the stationary part spaced apart from the movable part via an air gap therebetween.

Magnet assemblies of electromechanical assemblies for elevator systems are described. The magnet assemblies include a magnet, at least one rail engagement block, and an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material. A target extension is formed from the material of the encapsulating body and extends away from the magnet and the at least one rail engagement block. A proximity switch target is held within the target extension for detection by a proximity switch.

A braking device for an elevator with a rail-guided car, which encompasses a guide rail and holds a braking element in position on one side of the guide rail and holds another braking element in position on the opposite side of the guide rail, wherein at least one of the braking elements is held in its standby position by a switchable retaining magnet against the force of an automatic actuator. The braking element is automatically driven in between the basic body and the guide rail, if the car moves at the point in time at which the braking element abuts against the guide rail. The retaining magnet is equipped with an air gap reducing agent, which reduces or eliminates an air gap between the retaining magnet and the braking element such that the retaining magnet keeps the braking element magnetically trapped again, as soon as it is switched accordingly.

A braking apparatus, that brakes and measures load changes in an elevator car, includes a brake, a brake holding arrangement holding the brake on the car, a load measuring device measuring a force acting on a force transmission element and a load measuring device holding arrangement holding the load measuring device on the car. The brake can be displaced relative to the car in a force direction generated by the brake and the load measuring device is held on the car fixed relative to the car in the force direction. The force transmission element is operatively connected to the brake to measure a force acting between the brake and the load measuring device due to a relative displacement of the brake relative to the load measuring device. A connecting piece arrangement connects the load measuring device holding arrangement and the brake holding arrangement in an elastically deformable manner.
