摘要： An elevator balanced-load rescue device, an elevator, and an elevator balanced-load rescue method are provided by the present disclosure. The elevator balanced-load rescue device includes: a clamping wheel set including a driving wheel and a driven wheel that cooperate with each other; wherein the clamping wheel set has a clamping position and a releasing position; in the clamping position, the driving wheel and the driven wheel move toward each other to clamp a traction belt connected between an elevator car and an elevator counterweight; and in the releasing position, the driving wheel and the driven wheel move opposite to each other to release the traction belt; a transmission shaft which has a first end connected to the driving wheel of the clamping wheel set, and which transmits a torque to the driving wheel; and an energy storage device associated with the transmission shaft.

摘要： A limiting mechanism for an elevator compensation rope tensioning pulley, an elevator compensation apparatus including the limiting mechanism for an elevator compensation rope tensioning pulley, and an elevator system. The limiting mechanism for an elevator compensation rope tensioning pulley includes: a first limiting component, disposed on a frame of an elevator compensation rope tensioning pulley, and kept in position by a tensioning force of an elevator compensation rope together with the elevator compensation rope tensioning pulley and the frame; and a second limiting component, limited at a suitable position relative to a guiderail of the elevator compensation rope tensioning pulley, wherein a vertical distance within a predetermined range is kept between the first limiting component and the second limiting component, and, when an upward displacement of the elevator compensation rope tensioning pulley reaches the vertical distance, the first limiting component collides with the second limiting component.
