Abstract: A safety device configured to aid in braking movement of a hoisted object is provided including a mounting frame. A brake block is connected to the mounting frame and is operably coupled to a safety brake. An inner block assembly is disposed between the mounting frame and the brake block. The inner block assembly is movable relative to both the mounting frame and the brake block. Upon detection of a predetermined condition, the brake block is configured to engage and adjacent guide member to actuate the safety brake.

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: A brake (26) for an elevator system (10) and method of using the brake (26) is disclosed. The brake (26) may comprise first and second brake linings (38) configured to be frictionally engageable with a rail (14) of the elevator system (10), a first biasing member (34) configured to urge the first brake lining (38) to engage the rail (14), and a first actuator (30) configured to move the first brake lining (38) to disengage the rail (14) when the first actuator (30) is energized. The brake (26) may be configured to be mounted on an elevator car (16) of the elevator system (10).

Abstract: A braking system for an elevator system includes two or more braking surfaces located at an elevator car and frictionally engageable with a rail of an elevator system. One or more actuators are located at the elevator car and are operably connected to at least one braking surface of the two or more braking surfaces. The one or more actuators are configured to urge engagement and/or disengagement of the at least one braking surface with the rail to stop and/or hold the elevator car during operation of the elevator system. One or more braking guides are located at the elevator car to maintain a selected distance between the two or more braking surfaces and the rail.
