摘要： The invention relates to a mechanical brake operator system suitable for linear motor elevators providing low-cost and reliable braking without the need of power transmission for rope-less linear motor elevators. The mechanical brake operator system is also used by single-car or multi-car linear motor elevators operating on linear, curved, or branching trajectories.

摘要： A frictionless safety brake actuator (100), a braking system, and an elevator system. The frictionless safety brake actuator (100) for use in an elevator system, includes: a fixed component (110); a movable component (130), configured to be moveable between a first position in which a safety brake is actuated and a second position in which the safety brake is not actuated; a biasing element (120) arranged between the fixed component (110) and the movable component (130) to apply a biasing force to the movable component (130) to bias the movable component (130) away from the fixed component (120) towards the first position; an actuating element (140) connected to the movable component (130); a holding arrangement (150) comprising a latch (154) and a first actuator (152), wherein the first actuator (152) is configured to be selectively operable to move the latch (154) between a holding position and a release position.

摘要： An elevator system includes a guide rail, an elevator car, a safety brake actuator and a safety brake. The safety brake actuator and the safety brake are mounted to the elevator car to move along the guide rail with the elevator car in use. The safety brake actuator includes an actuation mechanism configured in use to actuate the engagement of the safety brake against the guide rail. The safety brake actuator also includes a proximal surface, the safety brake actuator is mounted adjacent to the guide rail with the proximal surface facing the guide rail and spaced from the guide rail to define a clearance gap between the guide rail and the proximal surface of the safety brake actuator.

摘要： 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.

摘要： 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.
