Abstract: An elevator maintenance kit is provided for surfacing an elevator sheave that engages with an elevator tension member. The kit includes a substrate with an adhesive backing, and a substrate applicator that is operable to apply the substrate to the sheave as the sheave is rotated. The adhesive backing is operable to attach the substrate to the sheave during the sheave rotation.

Abstract: A method of wear detection of a coated belt or rope includes connecting a wear detection unit to one or more monitoring strands and/or cords of a coated belt or rope. The coated belt or rope includes one or more baseline strands and/or cords exhibiting a first change in electrical resistance as a function of bending cycles of the belt or rope and one or more monitoring strands and/or cords exhibiting a second change in electrical resistance as a function of bending cycles of the belt or rope, greater than the first change in electrical resistance. An electrical resistance of the one or more monitoring strands and/or cords is measured via the wear detection unit. Using at least the measured electrical resistance of the one or more monitoring strands and/or cords, a wear condition of the belt or rope is determined.

Abstract: A belt of an elevator system includes one or more tension elements extending longitudinally along a length of the belt, and an elastomeric jacket at least partially enveloping the one or more tension elements. The jacket defines a traction side configured to be interactive with a traction sheave of the elevator system and a back side opposite the traction side. A protective tape is applied to the elastomeric jacket at the back side. A method of assembling an elevator system includes forming a belt, and installing the belt in a hoistway of the elevator system. One or more additional components of the elevator system are installed in the hoistway. A protective tape is removed from a jacket of the belt after installation of the one or more additional components is completed.

Abstract: A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.

Abstract: An illustrative example embodiment of an elevator sheave liner includes a liner body having an inner surface configured to be received against a sheave and an outer surface configured to engage an elevator tension member. The liner body comprises a polymer material and a plurality of wear resistance particles in the composite material. The wear resistance particles are nanoparticles or microparticles. At least some of the wear resistance particles establish a traction characteristic of the outer surface of the sheave liner.
