Abstract
A method of forming a belt for suspending and/or driving an elevator car includes arraying a plurality of tension elements longitudinally along a belt and interlacing a plurality of warp fibers and a plurality of weft fibers with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure. The coating includes a base coating material and at least one additive mixed with the base coating material to improve an operational characteristic of the belt.
Claims19
A belt for suspending and/or driving an elevator car, comprising:
- a plurality of tension elements extending longitudinally along a length of the belt;
- a plurality of warp fibers and a plurality of weft fibers interlaced with the plurality of tension elements forming a composite belt structure;
- and
- a coating at least partially covering the plurality of tension elements, the plurality of warp fibers and the plurality of weft fibers, the coating including:
- a base coating material;
- and
- at least one additive mixed with the base coating material to improve an operational characteristic of the belt;
- wherein the additive includes one or more of alumina, silica, Mania, graphite, chopped fiber, melamine salts, zinc powder, graphene, talc, Al/Mg hydroxide, exfoliated clay platelets, carbon black, carbon nanotubes, or clay;
- wherein the coating includes a first coating layer having a first viscosity and a second coating layer applied over the first coating layer, the second coating layer having a second viscosity greater than the first viscosity.
