  • the leveling device is used to prepare surfaces before laying asphalt, bituminous coatings, or other construction materials. It helps create flat, uniform, and high-quality surfaces, ensuring the safety and durability of road infrastructure.
  • the leveling device In residential, commercial, or industrial construction projects, the leveling device is used to prepare the ground by leveling the areas where buildings will be erected, adjusting slopes, and removing irregularities. It is also used for the finishing layer.
  • the leveling device is essential for earthworks, whether for creating construction platforms, preparing foundations or developing storage areas.
  • the grading device is used to repair, renovate, or create new roads, sidewalks, bike paths, trenches, and other urban features.
  • the leveling device is used to prepare landing surfaces, docks and other necessary facilities.
  • the leveling device is also used for regular maintenance of existing infrastructure, repairing damaged surfaces or restoring the levelness of roads and terrain.
  • the document can also be cited US20190040606 presenting a box-shaped blade earth leveling tool and the document US20100326684 describing a leveling system and method.

  • Each skid is independently height-adjustable relative to the main blade, allowing the blade to rise or fall relative to the base of the skids.
  • the skids thus positioned serve as a reference for the leveling height.
