Abstract: An elevator car or counterweight, comprising a frame, the frame including an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight.

Abstract: The present invention provides a safety device for elevators, which belongs to the field of elevator safety technologies. The safety device for elevators includes a housing; a safety piece having a guide rail groove, the safety piece being disposed in the housing; and asymmetric active and counter wedges that are slidably disposed on the safety piece at both sides of the guide rail groove, respectively. Moreover, the device further includes a U-shaped elastic element and a blocking piece that are disposed on the safety piece. The safety device for elevators can provide a relatively stable arresting force, is reliable in repetitive work, achieves high safety, is relatively easy as well as fast and efficient in restoration, and is especially suitable for high-speed elevators.

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 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.
