Abstract
A device for cleaning elevator ropes includes a carpet strip clamped to be in contact with the elevator ropes and includes an additional supply roll of carpet. Once the portion of the carpet strip that comes into contact with the elevator ropes becomes soiled, the carpet strip can be advanced so that a clean portion of the carpet strip is positioned to be in contact with the elevator ropes and the soiled portion of the carpet strip is discarded. The carpet strip is secured by a pair of labyrinth type clamps that can be loosened and tightened without use of additional tools.
