摘要： An adjacent safety configuration (80) for an elevator includes a second pair of safeties (50) displaced from a first pair of safeties (40) by at least 0.1 seconds of travel time at a rated speed of the elevator. An adjacent safety configuration (80) for an elevator includes a second pair of safeties (50) displaced from the first pair of safeties (40) to provide a predetermined time period before the second pair of safeties pass over a point on a guide rail (16) previously passed over by the first pair of safeties (40) to permit the guide rail surface to decrease by a predetermined temperature. A method of spacing an adjacent safety configuration (80) for an elevator system includes de-rating a pair of trailing safeties (50) with respect to a pair of leading safeties (40) as a function of a rated speed of the elevator and a spacing between the pair of trailing safeties (50) and the pair of leading safeties (40).

摘要： 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.

摘要： The present invention provides a safety device (10) for elevators. The safety device (10) includes a housing (110); a safety piece (120) having a guide rail groove (121), the safety piece (120) being disposed in the housing (110); and asymmetric active and counter wedges (130,140) that are slidably disposed on the safety piece (120) at both sides of the guide rail groove (121), respectively. Moreover, the device further includes a U-shaped elastic element (150) and a blocking piece (160) that are disposed on the safety piece (120). The safety device (10) 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.
