A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.

Abstract: A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of fibers. A metallized coating layer is applied to at least a portion of an outer surface of at least one tension member of the plurality of tension members. The metallized coating has a coating electrical conductivity greater than a tension member electrical conductivity of the at least one tension member. A jacket material at least partially encapsulates the plurality of tension members and the metallized coating layer.

Abstract: An elevator system includes an elevator car, a motor, and traction sheave operably connected to the motor to drive rotation of the traction sheave. A belt is operably connected to the elevator car and in frictional contact with the traction sheave to urge movement of the elevator car. One or more deflector sheaves are located between the traction sheave and the elevator car over which the belt is routed to guide the belt to the elevator car. The one or more deflector sheaves include an outer sheave surface having a distance from a sheave axis that varies along a width of the traction sheave. The outer surface includes a first portion having a first coefficient of friction and a second portion having a second coefficient of friction less than the first coefficient of friction, the first portion guiding an elevator belt toward a lateral center of the outer surface.

Abstract: A resurfacer for a belt of an elevator system includes a resurfacing roller having a selected surface roughness and a heater element to heat the belt to a selected temperature. A biasing element urges the resurfacing roller into contact with the belt and applies a selected pressure to the belt. A method for altering a surface roughness of a belt of an elevator system includes positioning a resurfacing roller having a selected surface roughness at an outer surface of the belt and heating the belt to a selected temperature. A selected pressure is applied to the belt via the resurfacing roller. The belt is passed along the resurfacing roller and the surface roughness of the belt is altered via the resurfacing roller.

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.
