Patents Assigned to Barr Fabrication
  • Publication number: 20200149299
    Abstract: The disclosure relates to a work over platform apparatus, system, and method of use with trenches and cellars. The apparatus includes two platform portions joined at the center by a set of hinges. The set of hinges is divided to allow for cutouts in each of the platform portions. When deployed the cutout portions are aligned to form an opening that allows work personnel to access the cellar through the work over platform. The work over platform may be collapsed along its hinges for compact transport to and from a work site. The system includes multiple apparatuses positioned adjacent to one another along the same cellar. Outriggers for guidelines are positioned in a novel spider leg fashion to allow greater accessibility to the platform by vehicles. The method includes deploying, using, and collapsing the apparatus.
