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: A tension member termination device optimized for terminating flexible flat tension members, the device including a socket with a compression portion and a bulbous portion and a compression plate on each side of the compression portion fastenable by fasteners extending through all of these feature. The device provides a pathway for the tension member through the device and upon torquing the fasteners reliably secures the tension member while avoiding deleterious pressure and stress therein. The invention also provides a safety clamp for optional use with the invention.

Abstract: A device (22) for damping vibrations between a first component (16) and a second component (14) includes a receiving member (24) configured to be connected to the first component (16), a first permanent magnet (26) arranged inside the receiving member (24), a second permanent magnet (28) arranged inside the receiving member (24) in series with the first magnet (26), and an engaging member (30) slidably connected to the receiving member (24) and including a first end configured to engage the second component (14) and a second end inside the receiving member (24) adjacent the first magnet (26). The second magnet (28) includes a pole which repels a facing pole of the first magnet (26).

Abstract: An elevator brake assembly (16) includes a plate (26) having damper assemblies (28) including at least one spring (30) for controlling movement of the plate (26) relative to a magnetic field generator (20). A biasing member (36) forces the plate (26) into engagement with a disk (22) fixed to a rotating shaft (18). A force created by the magnetic field generator (20) overcomes force of the biasing member (32) to draw the plate (26) into contact with the magnetic field generator (20). The impact between the plate (26) and the magnetic field generator (20) is controlled by the damping assembly (28) to substantially reduce impact noise.

Abstract: A device (30) for making electrically conductive contact with at least one tension member in an elevator belt (22) also provides a restraining feature to support loads on the belt. A connector portion (32) is secured to the belt. In one example, the connector portion (32) includes clamping members (40, 42) that are received on opposite sides of the belt. One of the clamping members supports a plurality of electrically conductive connector members (52) that establish electrical contact with selected tension members (24) within the belt (22). A plurality of load transferring members (66) are supported by the other clamping member in one example. A restraining portion (34) is adapted to be secured in a fixed position relative to a selected structure (36) within the elevator system.

Abstract: An elevator system includes a hoistway having a plurality of hoistway doors. An elevator car and counterweight are provided in the hoistway. A drive motor is drivingly coupled to the elevator car and counterweight, and is located adjacent to either the top or bottom portion of a hoistway door so as to eliminate the need to provide a machine room above the hoistway ceiling.

Abstract: A device for securing an end on a load bearing member in an elevator system includes a socket portion and a wedge portion. The socket and wedge preferably are made from an extruded piece of metal or a formed piece of sheet metal material. A brace member secures the wedge within the socket portion to maintain the wedge, and the corresponding portion of the load bearing member in place within the socket portion. The preferred arrangement includes friction enhancing surfaces on the corresponding portions of the socket and the wedge to facilitate maintaining the load bearing member in place.

Abstract: An elevator system includes an elevator hoistway defined in a surrounding structure, such as a building. An elevator car and counterweight are located in the hoistway. A drive motor and associated drive sheave are disposed at a bottom portion of the hoistway. The drive motor is coupled to the elevator car and the counterweight via at least one flat rope for moving the elevator car upwardly and downwardly along the hoistway.

Abstract: A termination device for terminating a flexible flat tension member includes a socket and two opposing wedges mounted therein. One of the wedges is preferably pinned within the socket while the other wedge is removable. The invention provides a reliable termination with a safety back-up to retain the tension member even if friction in the device is reduced due to soiling with a friction reducing material.

Abstract: A segmented elevator sheave assembly has independently variable shoulder and crowning elements for use with flexible flat ropes in an elevator system. This enables selection of high-traction surface finish and crowning for the sheave groove that contacts a belt, and of low-traction, smooth sheave groove shoulders having a low friction coefficient that may inadvertently contact the belt side surfaces. This configuration is more forgiving to angular misalignment of the sheave and reduces the likelihood of premature degradation of a flat flexible rope due side-surface scuffing along sheave groove shoulders.
