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.

Stabilizing device of elevator car and a control method thereof, an elevator system

The present invention provides a compensation chain stabilizing apparatus and method, and an elevator shaft and elevator system having the same. The compensation chain stabilizing apparatus for an elevator includes a magnetic field generating device, which is configured to generate a magnetic field to limit shaking of the compensation chain. The elevator shaft and elevator system according to embodiments of the present invention include the compensation chain stabilizing apparatus according to the embodiments of the present invention. The apparatuses and methods of the present invention can suppress shaking of the compensation chain as much as possible, and avoid other problems related to the shaking of the compensation chain.

Compensation chain stabilize device and method, hoistway and elevator system

A stabilization apparatus of an elevator car includes: a base fixedly mounted with respect to the elevator car; an upper swing arm and a lower swing arm disposed in parallel basically, first ends thereof being pivotably fixed to the base; a guide rail friction member capable of generating, with the guide rail, a frictional force for keeping static with respect to the guide rail, and having a first connecting shaft and a second connecting shaft for being connected to the upper swing arm and the lower swing arm respectively; and a damper having at least one end connected to the upper swing arm or the lower swing arm, wherein the damper is configured to at least partially prevent the upper swing arm and the lower swing arm from relatively swinging, with the first connecting shaft and/or the second connecting shaft as a swinging pivot.
