A lifting equipment is provided. The lifting equipment may include a working assembly, a safety assembly, and a shaft assembly. The working assembly may include a working fastener. The working fastener may be spirally connected to the shaft assembly. When the shaft assembly rotates the working fastener may move along the shaft assembly. The safety assembly may comprise a limiting component. The limiting component may be connected to the working fastener. A portion of the safety assembly may be in located a space between the limiting component and the working assembly.

The invention relates to a free fall winch comprising a drum, which can be rotationally driven by a winch drive, wherein a free fall brake is provided for braking the drum in free fall operation. According to the invention, a torque acting on the free fall winch, which depends on the free fall braking torque, is detected by means of a detection device, and a brake actuation force with which the free fall brake is actuated is controlled or adjusted by a control device according to the detected torque.

A brake device includes: a fixed member; a moving member which is movable between a retracted position in which the moving member is adjacent to the fixed member and separate from a braking member, and a braking position in which a friction plate of the moving member contacts the braking member and provides a braking force to the braking member; an elastic member connected between the moving member and the fixed member; a coil disposed in the fixed member; and a controller which provides an operating current to the coil when the elevator is in normal operation, wherein the controller is configured to implement a test mode in which the controller provides a test current less than the operating current to the coil and determines whether the moving member has been attracted to the retracted position.

A braking device, a braking system for an elevator, and an elevator system. The braking device comprises a braking unit and an actuating unit arranged to cause the braking unit to be in a braking state to provide a braking force to a mating external component, or in a non-braking state to stop providing the braking force to the external component, and the braking device further comprises a vibration isolating member with non-linear rigidity, for providing an effect of damping and vibration isolation between the actuating unit and the braking unit at least in the non-braking state.

A disc locking device, comprising: a base, a brake clamping block, a support mechanism, a front baffle, a limiting cover plate, a needle roller slide plate and a brake triggering mechanism, and so on. The base includes a bottom plate and two side vertical plates which are integrally arranged on the bottom plate; the two side vertical plates are oppositely arranged, and the inner walls thereof are all lateral slope surfaces, so that a wedge-shaped groove having a large front opening and a small rear opening is formed between the two laterally-vertical plates; and mounting holes penetratingly connected to the brake triggering mechanism are formed on the side vertical plates. The support mechanism includes a front support mechanism and a rear support mechanism.

Elevator systems are described that include a traveling component movable along a guide rail and an overspeed safety system. The safety system includes a safety brake connected to an electromechanical actuator. A safety brake element of the safety brake is operable to engage with the guide rail to stop the traveling component. The electromechanical actuator includes a frame, a first magnetic element operably connected to the safety brake, a second magnetic element movably attached to the frame, and a third magnetic element fixedly attached to the frame. The second magnetic element is movable to urge the first magnetic element from a first position toward a second position. In the second position, the first magnetic element is located proximate the third magnetic element. As the first magnetic element transitions from the first position to the second position, the safety brake element is actuated into engagement with the guide rail.
