    Abstract: An elevator system includes one or more rails fixed in a hoistway and an elevator car configured to move through the hoistway along the one or more rails. The system includes one or more braking systems having one more braking surfaces secured to the elevator car and frictionally engageable with one or more rails of the elevator system. One or more actuators are operably connected to the one or more braking surfaces configured to urge engagement and/or disengagement of the one or more braking surfaces with the rail to stop and/or hold the elevator car during operation of the elevator system.

    Abstract: An exemplary brake device includes a brake element configured to apply a braking force to resist rotation of an associated component. A mounting member is configured to mount the brake device to a stationary surface. The mounting member is at least partially moveable relative to the stationary surface responsive to a torque on the brake device. A sensor provides an indication of a force associated with any movement of the mounting member relative to the stationary surface responsive to the torque.

    Abstract: The device for controlling movement of a plurality of elevator cars in a single hoistway includes a door monitor module (46) that facilitates controlling movement of elevator cars (22, 24). The door monitor module (46) is configured to determine when at least one door (30) along a hoistway (26) is open. The door monitor module (46) places a first relay (52) in a selected operative state if a first elevator car (22) is stopped at a landing corresponding to the at least one open door. The door monitor module (46) places a second relay (56) in a selected operative state if a second elevator car (24) is stopped at a landing corresponding to the at least one open door. The door monitor module (46) is also configured to place both relays (52, 56) into the selected operative state if neither of the elevator cars (22, 24) is stopped at a landing corresponding to an open door (30) along a hoistway (26).

    Abstract: A pair of elevator cars (10, 11) traveling in the same hoistway have their positions sensed (20-23, 29-32) to provide for each a position signal (35, 37) from which velocity signals (64, 65) are derived; lookup tables (66, 61) of safe stopping distance (B, S) for braking and safeties are formed as a function of all possible combinations of velocity (V(U), V(L)) of said cars. Comparison of safe stopping distances for contemporaneous velocities of said cars with actual distance between said cars provides signals (85, 98, 99) to drop the brakes (49, 50) of one or more of the cars, and provides signals (82) to engage the safeties (18, 18a, 19, 19a) of all cars if the cars become closer or if acceleration detectors (117, 118) determine a car to be in freefall.
