Abstract: This disclosure relates to a cooling system for an elevator with electronic visual displays, and a corresponding method. An example system includes an elevator car having an inner wall, and an electronic visual display mounted to the inner wall so as to define a gap between the inner wall and the electronic visual display. Further, fluid is configured to flow through the gap to cool the electronic visual display.

Abstract: An exemplary elevator system includes an elevator car having an integrated cabin and car frame structure including a platform thickness between a floor surface in the cabin and a lowermost surface on a support beam used for supporting the car beneath the floor surface. A sheave assembly is supported beneath the floor surface. The sheave assembly includes a plurality of sheaves and a plurality of subframe beams. The sheaves and subframe beams fit within the platform thickness such that the subframe beams and the sheaves are no lower than the lowermost surface on the support beam. A plurality of isolation members are between the sheave assembly and the elevator car for isolating an interior of the cabin from vibrations associated with movement of the sheaves.

Abstract: A damping device for damping movement of a parked car in an elevator system includes a base plate and at least one damping assembly connected to the base plate. The damping assembly includes a flange extending from the base plate, a support member arranged at a distance from the flange, and at least one damping mechanism having a first end connected to the flange and a second end connected to the support member. The at least one damping assembly restricts movement of the support member toward the flange.

Abstract: Elevator car guiding devices including a roller guide frame including a mounting base to be mounted to an elevator car, a first roller supported on the mounting base, the first roller having a first roller wheel configured to engage with and rotate along a guide rail and prevent movement of the elevator car in a first direction, a second roller supported on the mounting base, the at least one second roller having a second roller wheel configured to engage with and rotate along the guide rail and prevent movement of the elevator car in a second direction, and a motion state sensing assembly mounted to the roller guide frame and configured to measure a motion state of the elevator car within an elevator shaft of the elevator system.
