摘要： An elevator system includes a hoistway and an elevator car moveable along the hoistway. A drive system is located in the hoistway and is operably connected to the elevator car to urge movement of the elevator car along the hoistway. A safety system to establish a protected volume in the hoistway includes a prop installable in the hoistway to prevent downward movement of the elevator car and a plurality of relays configured to detect faults in the elevator control system to prevent movement of the elevator car prior to installation of the prop.

摘要： A testing arrangement (36) for testing the operability of at least one safety sensor (21, 22, 23, 26, 28) connected to the safety chain (30) of an elevator system (1), the testing arrangement (36) comprises: at least one test circuit (34) for testing the operability of the at least one safety sensor (21, 22, 23, 26, 28); and at least one testing relay (32, 33). The testing relay (32, 33) is switchable between an operational position and a test position and it is configured for electrically connecting the at least one safety sensor (21, 22, 23, 26, 28) to the safety chain (30) in the operational position and for electrically connecting the at least one safety sensor (21, 22, 23, 26, 28) to the test circuit (34) in the test position.

摘要： An exemplary method is useful for controlling movement of an elevator car in an elevator system that includes a machine that selectively moves the elevator car and a machine brake that selectively resists movement of the elevator car. The method includes determining whether the elevator car is near a landing and determining whether a door of the elevator car is open. A desired operation includes desired movement of the elevator car while the elevator car is near the landing and the door is open. A determination is made whether the elevator car moves other than according to the desired movement. The machine brake is applied for stopping movement of the elevator car responsive to elevator car movement other than the desired movement while the elevator car is near the landing and the door is open.
