  • Patent number: 10532910
    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.

  • Patent number: 10364128
    Abstract: An assembly for controlling a vertically extending member includes a device having a stop member and a speed control member for controlling movement of the vertically extending member such as an elevator load bearing member during a roping procedure. In a disclosed example, the stop member is biased into a stop position where the vertically extending member is locked between a brake pad and a guiding member so that the vertically extending member cannot move relative to the device. An example input member for moving the stop member out of the stop position comprises a foot pedal that can be manipulated to control a position of the stop member. Absent manual manipulation of the input member, the stop member prevents movement of the vertically extending member. In a disclosed example, a speed control member comprises a pad that selectively engages a vertically extending member responsive to manual manipulation of a handle for moving the pad relative to a base of the device.

  • Patent number: 9701515
    Abstract: An exemplary elevator system includes an elevator car (22) having an integrated cabin and car frame structure including a platform thickness (T) 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 (26) 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 (T) 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 (26).

  • Patent number: 9604823
    Abstract: An assembly for controlling a vertically extending member includes a device (22) having a stop member (34) and a speed control member (36) for controlling movement of the vertically extending member such as an elevator load bearing member (32) during a roping procedure. In a disclosed example, the stop member (34) is biased into a stop position where the vertically extending member (32) is locked between a brake pad (60) and a guiding member (54) so that the vertically extending member (32) cannot move relative to the device (22). An example input member for moving the stop member (34) out of the stop position comprises a foot pedal (70) that can be manipulated to control a position of the stop member (34). Absent manual manipulation of the input member, the stop member (34) prevents movement of the vertically extending member (32).

  • Patent number: 7857115
    Abstract: A device (42) useful for working on an escalator (20) provides a tread surface (50) that is obliquely oriented relative to an incline (I) of the escalator (20) during a maintenance or repair procedure. A disclosed example is useful for spanning at least a portion of an escalator (20) where the normal operating steps (22) have been removed for purposes of working on the escalator (20). A disclosed example includes a tread surface (50), a riser portion (52) that is at least partially generally perpendicular to the tread surface (50), a first axle hook (54) and a second axle hook (56). The axle hooks rest upon spaced axles (46) associated with the escalator for positioning a temporary step (44) as desired for facilitating working on the escalator.
