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: An elevator safety gear actuation device for actuating an elevator safety gear comprises a first member and a second member. The first and second members are arranged opposite to each other defining a gap configured for accommodating a guide member extending in a longitudinal direction. At least one of the members is movable in a direction transverse to the longitudinal direction between a disengaged position and an engaged position. The first member comprises at least one permanent magnet which is configured for being magnetically attracted and attaching to the guide member extending through the gap when the first member is arranged in the engaged position the second member comprises at least one roller and/or at least one low friction element configured for providing low friction between the second member and the guide member extending through the gap.

Abstract: A method of manufacturing an elevator safety spring is provided. The method includes determining a plurality of dimensional parameters of the elevator safety spring. The method also includes selecting a plurality of dimensions within the dimensional parameters. The method further includes manufacturing the elevator safety spring based on the selected parameters, the elevator safety spring having an I-beam cross-section.
