Abstract: A jumping elevator system and a jumping method used in construction process of building. The jumping method includes preliminarily positioning and mounting, by means of a temporary working platform at a first height, a guide rail on the hoistway 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 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 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.

Abstract: 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.

Abstract translation: 电梯制动力矩的检测方法解决了现有技术中的制动检测装置的操作需要手动执行的问题，制动检测装置不方便和便于操作，功能是单数和制动力矩变化趋势 制动磨损趋势无法体现。 在该方法中，通过向电动机输入分段转矩电流，判定电动机旋转期间的转矩是否在制动器的设计力矩范围内，可以确定制动器的转矩是否足够，并且可以分析制动磨损趋势 根据每次记录的扭矩。 该方法周期性进行自动检测，功能多样化，检测精度高，可反映制动力矩变化趋势，制动磨损趋势也可以体现。

Abstract: An elevator emergency operation device with safety function testing capability. The device includes a connection unit and a control unit. The connection unit includes a first connection component adapted to be connected with a car status detection device and a second connection component adapted to be connected with a holding brake controller. The control unit is connected with the connection unit and is configured to perform various operations. In one operation, an elevator emergency operation function is performed in a first configuration state in which the first connection component and the second connection component are connected with the car status detection device and the holding brake controller, respectively. In another operation, in the first configuration state, releasing a holding brake associated with the holding brake controller and determining whether a seal star function is normal based on a first car status signal provided by the car status detection device.
