Abstract: An elevator system includes a linkage, a control system and a friction belt drive. The linkage is adapted to attach to an elevator door. The friction belt drive is adapted to move the elevator door with the linkage between an open position and a closed position. The friction belt drive includes a v-belt with one or more markers arranged along a length of the v-belt. The control system is adapted to control the friction belt drive, and includes a sensor adapted to detect at least one of the markers.

Abstract: An exemplary elevator system comprises a machine support (30) including a first portion (32) situated in a generally horizontal position at least partially within a hoistway (24). A second portion (34) is oriented generally perpendicular to the first portion. The second portion has one end supported by a support surface (52) adjacent the hoistway such that a portion of a load of the machine support is transferred to the support surface. One end of the first portion (32) is supported by the second portion (34) and another end of the first portion is supported by a structural member at least partially in the hoistway such that a remainder of the load of the machine support is transferred to the structural member.

Abstract: An elevator system (20) includes multiple elevator cars (22, 32) within a hoistway (26). Counterweights (24, 34) are associated with the respective elevator cars (22, 32) by load bearing members (40, 50). In some examples, different roping ratios are used for the load bearing members (40, 50). In some examples, the lengths of the load bearing members (40, 50) are selected to allow contact between the counterweights (24, 34) within the hoistway (26) and prevent contact between the elevator cars (22, 32). The difference in car and counterweight separation distances is greater than a stroke of a counterweight buffer plus an expected dynamic jump of the elevator cars. A disclosed example includes passages (80) through a portion of at least one of the elevator cars (22) for accommodating the load bearing member (50) of another elevator car (32) located beneath the elevator car (22) with the passages (80).

Abstract: An elevator door hanger apparatus includes a door hanger configured to be attached to a top portion of a door panel and to at least one movable member and an isolator plate attached to the door hanger and including a lip extending from a bottom of the isolator plate away from the door hanger.

Abstract: An elevator system (20) includes an underslung car (22). A plurality of load bearing members (32-38) are closer together behind the elevator car and spaced farther apart near a front of the elevator car (22). A plurality of sheaves (40-44) are supported for vertical movement with the car and rotational movement relative to the car (22) such that the load bearing members (32-38) can be arranged in a 2:1 roping ratio and extend underneath the car (22). A disclosed example includes sheaves (40-44) rotatable about sheave axes that are at oblique angles relative to corresponding edges of the elevator car (22).

Abstract: An elevator system (20) includes multiple elevator cars (22, 32) within a hoistway (26). Counterweights (24, 34) are associated with the respective elevator cars (22, 32). Frangible buffers (40, 38) are associated with at least one of the elevator cars (22, 32), the counterweights (24, 34) or both. In a disclosed example, buffer activators (42, 39) operate to break at least a frangible portion of the frangible buffers (40, 38) to dissipate energy associated with a collision or near collision between the elevator cars (22, 32) or the counterweights (24, 34).

Abstract: An elevator system (20) includes a buffer assembly (30) having buffers (32) spaced apart such that at least a portion of a counterweight (24) is received between the buffers (32) before the buffers interact with the counterweight. In a disclosed example, a strike member (60) has strike surfaces (62) that contact ends (38) of the buffers (32) after a substantial portion of the counterweight (24) has proceeded vertically below the ends (38) of the buffers.
