  • Enhancement method and apparatus for escalator or moving walkway
    Patent number: 8020687
    Abstract: An apparatus is used to enhance the standing-surfaces of platform-components of an escalator or a moving walkway which moves in a continuous loop. The apparatus is maintained in a constant position relative to the moving parts of the escalator or walkway such that, while in that constant position, all the standing-surfaces continually pass under the apparatus as a result of the continuous loop of the escalator. When the escalator is in operation, an applicator-means of the apparatus applies a flowable enhancement-material, in situ, to the standing-surfaces of the moving platform-components. The material solidifies thereon to enhance the surface characteristics of the standing-surfaces of the escalator, or moving walkway as the case may be.
