Abstract: The present invention provides a damper of an elevator car, a control method of the damper, and an elevator system, belonging to the technical field of elevators. The damper of the present invention includes a base, a clamping mechanism mainly including two clamp arm components, a solenoid drive part, and a link transmission component, wherein the link transmission component is configured to be movable in a direction approximately perpendicular to a guide surface and drive at least one of the two clamp arm components connected thereto to move towards a guide rail. The control method of the present invention can enable the damper to work in a disengaged state, a slight contact state or a damping output state.

Abstract: 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.
