A sheave liner for an elevator system sheave that supports a hoist rope with an elevator car suspended therefrom is replaced without having to remove the hoist ropes and without having to hang the elevator car by means other than the hoist ropes. The existing liner is cut and removed while the elevator car is suspended from the hoist ropes resting on the sheave. The new liner is rotated into its position and two ends of the liner are joined by either a mechanical bond or by a room temperature adhesive bond.

Method of replacing sheave liner

A cleaning device for removing sludge build-up from elevator ropes includes a brush assembly secured within a housing and shielded by a guard. The sludge is continuously removed from the elevator ropes as the elevator ropes pass through the bristles of the brush. The housing includes a removable receptacle where the removed sludge is collected. The receptacle is periodically removed and cleaned. The cleaning device also includes a cleaning bar which removes the sludge from the brush to provide more effecting cleaning of the elevator ropes.
