An exemplary vertically moveable elevator system component includes a top portion, a bottom portion and a plurality of vertically oriented side portions between the top and bottom portions. At least one of the side portions includes a roller guide support sheet. A first roller guide roller is supported by the sheet such that the first roller is at least partially disposed on a first side of the sheet and an axis of the first roller is generally parallel with the sheet. Second and third rollers are supported by the sheet such that the second and third rollers are on a second, oppositely facing side of the sheet. An axis of each of the second and third rollers is generally perpendicular to the axis of the first roller. The axis of each of the second and third roller remains in a fixed position relative to the sheet.

An elevator door subsystem including a hanger mount, a leveling cam, an engaging member, and a roller assembly, configured such that when the roller assembly is positioned on one side of the elevator door hanger, the hanger mount is positioned within an opening of the elevator door hanger, and the leveling cam is positioned on another side of the elevator door hanger, the engaging member is receivable by the roller assembly after the engaging member is passed through an opening in the leveling cam, an opening in the hanger mount, and the opening in the door hanger.

Methods and systems of controlling elevators including detecting a landing stop for an elevator car, measuring load information associated with the stop, controlling stopping of the elevator at the landing using a machine based on at least one of the detected landing and the measured load information and performing dynamic compensation control of a motion state of the elevator with a computing system and the elevator machine. The dynamic compensation control includes receiving motion state information related to at least one motion state of the elevator car at the computing system, receiving the landing and load information at the computing system, applying a filter to the received information and generating a first control signal, and producing a control output from the first control signal to control the elevator machine to minimize oscillations, vibrations, excessive position deflections, and/or bounce of the elevator car at the detected landing.

An elevator system, suitable both for normal operating situations and for emergency situations, includes an elevator car that can be displaced directly or indirectly within an elevator shaft, a guide means that is connected to the elevator car, a derailment protection device that is connected to the elevator car, and a guide rail that has a first subregion which works together with the guide means and is used to guide the elevator car along the guide rail, and that has a second subregion which works together with the derailment protection device. A clearance between the derailment protection device and the second subregion of the guide rail is large enough that the derailment protection device and the second subregion of the guide rail remain spaced apart from each other during the normal operating situations.

A system for transferring elevator cars from a first elevator shaft to a second elevator shaft including: a first propulsion system configured to move a first elevator car through the first elevator shaft; a transfer carriage configured to move the first elevator car and the first propulsion system from the first elevator shaft to the second elevator shaft through a transfer station, the transfer carriage including: an elevator car containment slot to receive the first elevator car and the first propulsion system when the elevator car containment slot is aligned with the first elevator shaft, wherein the first propulsion system is configured to move the first elevator car and the first propulsion system from an elevator system within the first elevator shaft onto the transfer carriage to a vehicle workstation.

An elevator device includes a guide rail (1), a car (3), and a guide device (4). The car (3) is movable in a horizontal direction at a specific height. The guide device (4) includes a supporting member (11) and a guide member (12). The guide member (12) is displaceable to a first position for restricting movement of the car (3) in the horizontal direction and guiding up-down movement of the car (3) and a second position where the guide member (12) does not come into contact with the guide rail (1) when the car (3) moves in the horizontal direction.
