Abstract: 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.

Abstract: A brake actuator assembly for an elevator system. The assembly includes a safety brake. Also included is a bracket operatively coupleable to an elevator car. Further included is a first magnet operatively coupled to the bracket and rotatable between a first angular position and a second angular position. Yet further included is a second magnet operatively coupled to the bracket, the first and second magnets providing a repulsive magnetic force when the first magnet is in the second angular position to actuate movement of the safety brake into a guide rail.

Abstract: A damping device for damping movement of a parked car in an elevator system includes a base plate and at least one damping assembly connected to the base plate. The damping assembly includes a flange extending from the base plate, a support member arranged at a distance from the flange, and at least one damping mechanism having a first end connected to the flange and a second end connected to the support member. The at least one damping assembly restricts movement of the support member toward the flange.

Abstract: An elevator brake wedge is provided and includes an elongate body having first and second generally opposed major surfaces and first and second generally opposed minor surfaces. The second minor surface has a greater length than the first minor surface. Each of the first and second major surfaces extends between corresponding first and second ends of the first and second minor surfaces, respectively. The second major surface defines low-friction film securing grooves extending from a plane of the second major surface into the elongate body.

Abstract: A governor assembly is provided including a sheave rotatably mounted on a shaft and a ratchet disc mounted on the shaft. Rotation of the ratchet disc is restricted. An overspeed assembly includes a swing jaw mounted to the sheave. The swing jaw is movable between a normal position and a tripped position. The swing jaw is biased into the tripped position. When the swing jaw is in the tripped position, rotation of the sheave in a first direction is restricted. A tripping lever is pivotally mounted to the sheave and is configured to cooperate with the swing jaw. Rotation of the sheave in a second, opposite direction is configured to automatically move the swing jaw against its bias to the normal position.

Abstract: A tension member verification system of an elevator system includes one or more identifier elements located at the tension member. The one or more identifier elements include one or more configuration parameters of the tension member. A detector is positioned and configured to verify presence of the one or more identifier elements, and is configured to read the one or more configuration parameters of the tension member. An elevator system controller is operably connected to the detector and is configured to compare the detected one or more configuration parameters to stored configuration parameters stored at the elevator system controller, and take one or more actions in operation of the elevator system based on the result of the comparison.

Abstract: An overspeed assembly for use with a governor assembly for limiting of an elevator system, the overspeed assembly includes a rod movable relative to the governor assembly in response to a speed of an elevator car and a pin coupled to the rod. The pin is movable between a first position and a second position based on a direction of travel of the elevator car. The pin is configured to engage a first component to indicate a first overspeed condition when the elevator car is travelling in a first direction and the pin is configured to engage a second component to indicate a second overspeed condition when the elevator car is travelling in a second, opposite direction.

Abstract: A braking device is operable to aid in braking a hoisted object relative to a guide member. The braking device includes a mounting structure connected to the hoisted object, and first and second brake pads positioned on the mounting structure on opposing sides of a passageway through which the guide member extends. The first and second brake pads each include a contact surface that is operable to frictionally engage the guide member. The second brake pad engages the mounting structure in a manner that enables the second brake pad to move relative to the mounting structure between a non-braking position and a braking position. The braking device includes a brake initiator that is selectively operable to initiate movement of the second brake pad from the non-braking position toward the braking position by selectively actuating an actuatable portion of the brake initiator from a non-deployed position to a deployed position.

Abstract: An actuator assembly for an elevator governor system includes a governor for detecting an overspeed condition. Also included is a safety linkage actuating lever operatively coupled to the governor. Further included is at least one safety operatively coupled to the safety linkage actuating lever and configured to apply a braking force during an overspeed condition. Yet further included is a permanent magnet latch engaged with the safety linkage actuating lever, the permanent magnet latch preventing actuation of the safety by the safety linkage actuating lever during a normal speed condition. Also included is an electromagnetic component disposed proximate the safety linkage actuating lever and the permanent magnet latch and in operative communication with the governor, the electromagnetic component in an energized condition during the overspeed condition to overcome a force applied by the permanent magnet latch to the safety linkage actuating lever to actuate the safety.
