An auxiliary brake assembly for use in a hoist, is disclosed. The auxiliary brake assembly comprises a pinion, a fastener, and a clutch assembly. The pinion may comprise a mesh gear disposed proximate a respective mesh gear of a rotor gear. The clutch assembly may be disposed between the fastener and the mesh gear. The fastener may be configured to compress the clutch assembly in the event a cable drum of the hoist is free spinning. The compression of the clutch may lock the pinion and the rotor gear and stop the cable drum from spinning freely.

A winch including a drive motor, a cable drum, and a gear train assembly coupled to the drive motor and including a planetary gear set having a ring gear positioned in a gear train housing. The gear train housing including a radial clutch mount and an axial clutch mount. A clutch mechanism is selectively positionable at the radial clutch mount, in a first configuration, and the axial clutch mount, in a second configuration. The clutch mechanism is operable to selectively lock and unlock the ring gear to the gear train housing, thereby engaging and disengaging the cable drum from the gear train assembly.

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.

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.
