  • Patent number: 8733845
    Abstract: A trip hazard removing apparatus includes a saw head and blade connected to guide rail(s), which are connected to a support structure, which is connected to lift arm(s) of a vehicle. The vehicle moves the trip hazard removing apparatus between trip hazards occurring between upper and lower slabs of a sidewalk, placing it on the lower slab adjacent to and in contact with a trip hazard, and lifting it after removing the trip hazard. A trip hazard engaging mechanism automatically locates the saw blade's position and angle relative to and above the upper slab to create appropriate transition surface(s) between the upper and lower slabs as it cuts off the trip hazard. The guide rail(s) allow placing the saw blade facing the sidewalk's side surface. The saw head and blade are moved along the guide rail(s) across the upper slab and through the side surfaces to remove the trip hazard.
