Abstract: An adjacent safety configuration for an elevator includes a second pair of safeties displaced from a first pair of safeties by at least 0.1 seconds of travel time at a rated speed of the elevator. An adjacent safety configuration for an elevator including a second pair of safeties displaced from the first pair of safeties to provide a predetermined time period before the second pair of safeties pass over a point on a guide rail previously passed over by the first pair of safeties to permit the guide rail surface to decrease by a predetermined temperature. A method of spacing an adjacent safety configuration for an elevator system including de-rating a pair of trailing safeties with respect to a pair of leading safeties as a function of a rated speed of the elevator and a spacing between the pair of trailing safeties and the pair of leading safeties.

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: An illustrative example elevator assembly includes a first elevator cab and a second elevator cab. An H frame supports the first elevator cab and the second elevator cab. The H frame has a plurality of vertically oriented beams and at least one horizontally oriented beam extending between the vertically oriented beams. The at least one horizontally oriented beam is spaced from ends of the vertically oriented beams and the H frame does not have any horizontally oriented beam at either end of the vertically oriented beams. At least one linear actuator is coupled with the first elevator cab and the second elevator cab. The linear actuator is configured to selectively cause movement of the elevator cabs relative to the H 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.

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.
