Jack Or Jackstand Patents (Class D34/31)
  • Patent number: 12195925
    Abstract: A system and method for use in raising the height of railroad structures. Railroad structures are defined as the structures where two or more railway tracks merge, cross, or divide. The method utilizes excavating an opening beneath a railway track at or adjacent to a railroad structure. A hydraulic jack is positioned within the opening. This is repeated until sufficient hydraulic jacks have been positioned around the structure. The hydraulic jacks are then actuated to raise the railroad structure to a desired height. Generally this height provides a slight crown to the structure. Ballast is then positioned beneath the raised railway. The hydraulic jacks can be disconnected from the hydraulic lines and left in position, or removed. Preferably the hydraulic jacks are positioned on hydraulic jack sleds for improved ease in transporting the hydraulic jacks and to provide a platform on which the hydraulic jack is slid into and out of the opening beneath the railway.
