摘要： An elevator system (10) includes an elevator hoistway (12) having a plurality of landings (14), an elevator car (16) configured to move within the elevator hoistway (12), and a position determining system (40) having a plurality of landing position indicators (48) and a plurality of dummy position indicators (50). At least one of the landing position indicators (48) is mounted proximate to each of the plurality of landings (14). Each dummy position indicator (50) is mounted within the elevator hoistway (12) at a predetermined vertical position between various of the plurality of landing position indicators (48). The position determining system (40) additionally includes a sensor (42) configured to determine when the elevator car is adjacent one of the plurality of landing position indicators (48) or one of the plurality of dummy position indicators (50). The plurality of landing position indicators (48) and the plurality of dummy position indicators (50) are positioned to form a sequence of unique patterns. The position determining system is more cost effective and timesaving than the absolute position reference systems.

摘要： A detection method for elevator brake moment solves the problems that operation of the brake detection device in the prior art is required to be manually executed, the brake detection device is not convenient and facilitative to operate, the function is singular and the brake moment change trend and the brake wear trend cannot be reflected. In the method, by inputting stagewise torque current to the motor and determine whether the torque during rotation of a motor is within the design moment range of a brake, whether torque of the brake is enough can be determined and the brake wear trend can be analyzed according to torque recorded at each time. The method has advantages that the automatic detection is performed periodically, the functions are diversified, the detection accuracy is high, the brake moment change trend can be reflected and the brake wear trend can also be reflected.

摘要： The present disclosure relates to a jumping elevator system and a jumping method used in construction process of building. Embodiments of the jumping method comprise: preliminarily positioning and mounting, by means of a temporary working platform (160) at a first height, a guide rail (930) on the hoistway (910) substantially corresponding to the first height; removing the temporary working platform from the position, corresponding to the first height, of the hoistway; lifting, by use of a lifting assembly, a jumping platform (150) from a second height to a third height, wherein the third height is greater than the second height and less than or equal to the first height; and lifting, by use of the lifting assembly, the elevator car (110) to extend its traveling distance in the hoistway, and operating, during lifting of the elevator car, on the top of the elevator car for reinforcing the mount of the guide rail.

摘要： The present application relates to elevator safety technology, in particular to a device and method for detecting a seal star function of an elevator system and readable storage medium on which a computer program for implementing the method is stored. The device for detecting a seal star function of an elevator system according to one aspect of the present application comprises: an elevator door bypass unit configured to enable power supply to an elevator motor and a holding brake when an elevator car is located in a set area and to cut off the power supply to the elevator motor and the holding brake when the elevator car leaves the set area; a control unit coupled with a safety relay and the elevator door bypass unit and configured to perform the following operations: placing a landing door and an elevator door associated with a safety switch in a closed state and placing the safety relay in an opened state; bringing the elevator door bypass unit into an enabled state to replace a safety circuit to perform a control function of the power supply to the elevator motor and the holding brake; determining whether the seal star function is normal based on speed of movement of the elevator car within the set area.
