  • Modular and adaptable brake system for an elevator sheave
    Patent number: 7104367
    Abstract: An adjustable brake is provided that applies a braking force directly to an elevator sheave over which a cable suspends an elevator car and a counterweight. The brake includes a pair of calipers that apply a braking force to either longitudinal end of the sheave. The brake is spring set and may be released using, for example, electromagnetic, hydraulic or pneumatic forces. The calipers are mounted to and movable along a rail to enable adjustment of the location of the calipers. Further, the calipers are coupled together using one or more pins and are movable along the pins to enable adjustment of spacing between the calipers. The brake is particularly adapted for use with existing elevators because the brake does not require modification to the existing elevator sheave.
