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.
