Embodiments here are directed to an elevator stabilizing assembly for energy dissipation of an elevator assembly is provided. The elevator stabilizing assembly includes an actuator and a stabilizing device. The actuator is configured to move between a retracted position and an extended position. The stabilizing device includes an arm and a biasing member. The biasing member is coupled to the arm and biases the arm to move the arm between a disengaged position and an engaged position. When the actuator is in the extended position, the arm is moved into the engaged position when at least a portion of the arm is in contact with the fixed member of a hoistway. When the actuator is in the retracted position, the arm is moved into the disengaged position such that the at least the portion of the arm is free from contact with the fixed member of the elevator assembly.

A damper unit for an elevator, for the purpose of reducing vertical vibration of a stopping elevator car, has at least one roller that, in an active position, is in contact with a guide rail for the elevator car and can be rotated about an axis of rotation. For damping rotary movements during vertical vibration of the stopping elevator car, the roller is connected to a rotation damper.

A roller guide for an elevator car includes at least one roller rotatably mounted on an axis. The roller guide further includes a support element for supporting the axis, and at least one braking element for the roller for damping vertical oscillations of the elevator car. The brake element is a magneto-rheological fluid.

The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.

A roller system, a roller brake device and an elevator system. The roller brake device is used for the roller system. The elevator system includes the roller system. The roller system comprises a roller assembly and a roller brake device, the roller brake device includes: a body, the roller brake device is mounted to the roller assembly by the body; an actuation device mounted to the body; and a brake connected to the body in a pivotable manner, and the actuation device can move the brake from a rest position to a brake position, wherein the brake engages and brakes a roller in the roller assembly at the brake position, and the brake is disengaged from the roller at the rest position.

An elevator system and an elevator car. The elevator system includes one or more elevator cars traveling in an elevator hoistway along a guide rail, a shock absorbing device and a buffering device, the shock absorbing device is installed on at least one outside surface of the elevator car, and the buffering device is installed on an inside wall and/or a bottom of the elevator hoistway and configured to contact the shock absorbing device when the elevator car travels to lowest position along the guide rail.

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.

An elevator guiding device and an elevator system including the elevator guiding device. The elevator guiding device is configured to be installed on an elevator car and includes a biased member and a guiding and contacting member. The guiding and contacting member is connected to the biased member and is arranged to contact an elevator guiding rail when the elevator car is running in an unbalanced loaded state along the elevator guiding rail and cause the biased member to be biased, for guiding a running trajectory of the elevator car. The elevator guiding device further includes a connection member connected to the biased member and having an elastic member and a stop member, the elastic member is arranged to provide a pre-tightening force between the biased member and the connection member and provide a resistance force when the biased member is biased.
