摘要:
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 backup to retain the tension member even if friction in the device is reduced due to soiling with a friction reducing material.

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.
摘要:
A tension member termination device optimized for terminating flat tension members having compressible outer coatings, the device including a wedge and a socket each having cooperating surfaces positioned at a predetermined angle for clamping the tension member therebetween. The angle reliably secures the tension member while avoiding deleterious pressure and stress upon the tension member. The invention also provides a safety clamp for optional use with the tension member termination device.

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.
摘要:
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 features. The device provides a pathway for the tension member through the device and upon torquing the fasteners reliably secure the tension member while avoiding deleterious pressure and stress therein. The invention also provides a safety clamp for optional use with the invention.
摘要:
An elevator system having multiple machines and flat ropes is disclosed. In one embodiment, the machines are engaged in a series manner with a single set of ropes to drive the car and counterweight. In another embodiment, each machine is engaged with a separate set of ropes to drive the car and counterweight.
摘要:
An elevator guide system for flat rope tracking prevents the flat rope from hitting the shoulders on a rotating sheave to prevent premature degradation emitting objectionable sounds. The rope guide system includes one or more guide bodies having channels generally aligned with sheave grooves to which each block is adjacently positioned using a frame-mount. The guide bodies align the flat belt on entry into and exit from a sheave. The guide bodies may have a planar back surface, or a circular back surface, with the channel sidewalls disposed thereon and extending outwardly at right angles therefrom.
