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.

Methods and apparatuses for applying a substrate onto an elevator sheave

Handrail drive wheels on escalators and moving walkways are subjected to high stresses due to the pressures which are generated by the drive wheels in order to move the handrails. The operational stresses on the drive wheels require that they be securely mounted on their drive shafts. This mount assembly provides secure wheel-shaft coupling, while enabling the drive wheel to be easily removed from the drive shaft for servicing without the need to use any specialized tools. The wheels are provided with internal jack screws that can be manipulated with an Allen wrench to dislodge the wheel from the drive shaft.
