Abstract: Reinforced ground cover mats are used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a peripheral metal frame. A plurality of cross beam straps are disposed in transverse groove cut into the planar surfaces of the mat boards, and the ends are tucked within the frame members and lap welded.

Abstract: The invention is directed to reinforced ground cover mats which can be used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a metal frame. A structural support in the form of an I-beam encases the boards and frame on one side, and a tubular member such as a pipe on the other side, thereby increasing the strength at the middle of the mat ends. Further, the tubular member can be modified at its ends to facilitate insertion of a sling and stacking of adjacent mats. The mat also comprises means for lifting, including passages through which chains or cable may be threaded, lifting shackle assemblies or pear link assemblies.

Abstract: The invention is directed to interlocking ground cover mats that can be used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a metal frame. The side surfaces of the mats are connected using an interlock member and an interlock opening. The end surface of the mats is connected using a retaining pin that feeds through openings in perpendicular plates, or alternatively using complimentary pins and recesses.
