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.

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.
