Abstract: An elevator control system is configured to control an elevator car constructed and arranged to move along a hoistway defined by a stationary structure. The elevator system may include a communication pathway and a hoistway control system supported by the stationary structure and configured to send a continuous brake command signal over the pathway. A car control system is carried by the elevator car and is configured to receive the continuous brake command signal and initiate a brake Ustop mode upon a loss of the brake command signal, and independent of the hoistway control system.

Abstract: A method of fault detection of a belt or rope includes interconnecting a plurality of cords of the belt or rope, the cords including a plurality of wires, to form a bridge circuit. A fault detection bridge circuit is subjected to a voltage excitation and outputs a voltage which is indicative of the belt or rope damage but remaining insensitive to other environmental noises.

Abstract: A method of fault detection of a belt or rope includes connecting a fault detection unit to at least a portion of a belt or rope including a plurality of wires arranged in a plurality of strands and/or cords. At least the portion of the belt or rope is subjected to an AC voltage of high frequency range and an electrical impedance of the portion of the belt or rope is measured via the fault detection unit. Using at least the measured electrical impedance of the portion of the belt or rope, a fault condition of the belt or rope is determined.

Abstract: An illustrative example embodiment of a device for controlling movement of an elevator car includes an emergency stopping supervisor, such as a processor and memory associated with the processor. The emergency stopping supervisor is configured to: determine when an indication from an electrical protection device indicates that the elevator car should be stopped, issue a command for the elevator car to move at a reduced speed, monitor continued movement of the elevator car at the reduced speed, and continue to allow the elevator car to move at the reduced speed until a selected condition exists or immediately cause the elevator car to stop if the reduced speed is not within a predetermined range.

Abstract: An illustrative example elevator system includes a frame, a first elevator cab, a second elevator cab, and a plurality of sheaves associated with the first and second elevator cabs, respectively. A suspension assembly suspends the first and second elevator cabs within the frame. The suspension assembly has two ends in a fixed position relative to the frame. The suspension assembly includes a positive drive load bearing member along a first portion of a length of the suspension assembly and at least one other second load bearing member. A machine includes a drive sprocket that moves the positive drive load bearing member to cause movement of the first and second elevator cabs relative to the frame.

Abstract: A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.
