Abstract
A belt (30) for suspending and/or driving an elevator car (14) includes a plurality of tension elements (32) extending longitudinally along a length of the belt, at least one tension element of the plurality of tension elements having one or more tension element coating layers (46) applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating (44) at least partially encapsulates the composite belt structure.
Claims10
A belt for suspending and/or driving an elevator car, comprising:
- a plurality of tension elements extending longitudinally along a length of the belt, each tension element of the plurality of tension elements including one or more tension element coating layers applied thereto and wrapped individually entirely around a perimeter of each tension member;
- a plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure;
- and
- a belt coating at least partially encapsulating the composite belt structure;
- wherein the one or more tension element coating layers includes a fiber material.
An elevator system, comprising:
- a hoistway;
- a drive machine having a traction sheave coupled thereto;
- an elevator car movable within the hoistway;
- a counterweight movable within the hoistway;
- at least one belt connecting the elevator car and the counterweight, the belt being arranged in contact with the traction sheave such that operation of the drive machine moves the elevator car between a plurality of landings, the at least one belt including:
- a plurality of tension elements extending longitudinally along a length of the belt;
- one or more tension element coating layers applied to each tension element of the plurality of tension elements and wrapped individually entirely around a perimeter of each tension member;
- a plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure;
- and
- a belt coating at least partially encapsulating the composite belt structure;
- wherein the one or more tension element coating layers includes a fiber material.
