Having Scraper Blade Patents (Class 37/214)
  • Publication number: 20100258026
    Abstract: The object is to provide an obstacle-removing device for a removing obstacles on guideway, which is simple in configuration, low in manufacturing cost, and can remove the obstacles steadily and effectively, and of which the brushes for sweeping the running surface can be retracted easily when the device is in the rear side of traveling direction of the vehicle. The device comprises; a vertical frame positioned to the leading end in traveling direction of the vehicle, and a lifting/lowering device attached to the said vertical frame to lift and lower a brush holder attached to a vertically movable member which can be lifted and lowered by the lifting/lowering device, the brush holder having brushes for removing obstacles on the guideway; wherein the brush holder is pivotally attached to the vertically movable member such that the brush holder is tilting forward when the brushes held by the brush holder contact the running surface to perform obstacle-removing operation.
