A roller speed sensor for detecting a speed of an elevator car of an elevator system including: a first roller configured to rotate along a guide rail of the elevator system when the elevator car moves up or down an elevator shaft, the first roller including: one or more magnets; and a first sensor pair located proximate the first roller, the first sensor pair being configured to detect a rotational speed of the one or more magnets.

The present disclosure provides a guide device for an elevator car, and an elevator system. The guiding device includes: a roller guide frame; and at least one roller rotatably mounted to the roller guide frame, the roller being configured to roll on an elevator guide rail when the elevator car is moving; wherein the guiding device further includes a braking device which inhibits the rotation of the roller when activated. The device according to the embodiment of the present disclosure has a simple and compact structure.

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.

An illustrative example embodiment of an elevator system includes a platform and a plurality of supports configured to selectively engage a nearby structure. The plurality of supports include at least a first support and a second support. The first and second supports alternate between engaging the nearby structure to support the platform while the other one of the supports is disengaged from the nearby structure. At least one of the first and second supports is configured to move relative to the platform while engaging the nearby structure to cause vertical movement of the platform.

An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting movement of the tie down mechanism in at least one direction. At least one detector detects movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected movement.

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.

A method for installing an elevator system in an elevator shaft of a building in its construction phase uses a machine platform displaceable in the shaft along car guide rails and having a drive machine for moving a suspended elevator car to adapt a usable lifting height of the elevator car to an increasing height of the building by lifting the machine platform to a higher level. The method includes lowering a pre-assembled elevator unit into the shaft by a lifting device, using guide devices that are either mounted on the elevator unit and cooperate with stationarily fixed alignment elements in the shaft, or are fixed in the shaft and cooperate with alignment elements on the elevator unit, to align the unit in a position suitable for fitting guide shoes on the elevator unit and the car guide rails into one another.

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 guide having a bracket and a hub moveable relative to the bracket. A face arm and opposing side arms are connected to a cylindrical portion of the hub each having at least one guide member (e.g., wheel) or a gib assembly connected to the cylindrical portion of the hub. A self-centering hub spring is preferably provided. An adjustable hub spring force adjustment member for independently varying the spring force of the hub spring and an adjustable stop for independently adjusting the distance the hub can move away from an elevator rail are provided. The hub preferably includes one or more lubricant receiving members configured to enhance distribution of a lubricant. One or more components of the guide include one or more initial set-up markings that readily allow a user to position one or more components in an optimal set-up position to significantly reduce assembly time. The hub and hub spring are preferably configured to prevent the hub spring from falling out of the hub.

An illustrative example embodiment of an elevator includes an elevator car frame. A drive mechanism is situated near only one side of the elevator car frame. The drive mechanism includes at least one rotatable drive member that is configured to engage a vertical surface near the one side of the elevator car frame, selectively cause movement of the elevator car frame as the rotatable drive member rotates along the vertical surface, and selectively prevent movement of the elevator car frame when the drive member does not rotate relative to the vertical surface. A biasing mechanism urges the rotatable drive member in a direction to engage the vertical surface. At least one stabilizer is situated near the one side of the elevator car frame and is configured to prevent the elevator car frame from tipping away from the vertical surface.
