Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending along a length of the belt and a plurality of belt fibers transverse to the plurality of tension elements and interlaced therewith. The belt fibers define at least one traction surface of the belt. An edge fiber is located at a lateral end of the belt transverse to and secured to the plurality of belt fibers to secure the belt fibers in a selected position.
Abstract:
A compensation and tie-down member (60) for an elevator system includes one or more lightweight compensation tension elements (62a) having a first tensile strength / unit mass / unit length, and one or more heavier weight compensation tension elements (62b) having a second tensile strength / unit mass / unit length less than the first tensile strength / unit mass / unit length.
Abstract:
A belt for an elevator system includes a plurality of tension members arranged along a belt width and a jacket material at least partially encapsulating the plurality of tension members defining a traction surface, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer is applied via deposition of solid particles over at least one end surface of the two end surfaces.
Abstract:
A belt (30) for an elevator system (10) is provided. The belt (30) includes a plurality of tension members (42) arranged along a belt width (40). A jacket material (44) at least partially encapsulates the plurality of tension members (42). The jacket material (44) includes a traction surface (32) and a back surface (34) opposite the traction surface (32) together defining a belt thickness (36) therebetween. The jacket material (44) also includes two end surfaces (38) extending between the traction surface (32) and the back surface (34) and defining the belt width (40) therebetween. A metalized polymer coating layer (50) is disposed over at least one of the two end surfaces (38).
Abstract:
A belt (18) for an elevator system including a plurality of tension members (32) arranged along a belt width and a jacket material (36) at least partially encapsulating the plurality of tension members (32) defining a traction surface (28) interactive with a traction sheave of an elevator system and a back surface (30) opposite the traction surface (28). The back surface (30) includes a belt guide feature (42) extending along a belt length and interactive with a complimentary guide sheave feature (44) of a guide sheave (26) of the elevator system to orient the belt (18) to a selected location during operation of the elevator system.
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.
