Abstract: Mobile load handling apparatus for handling elongated loads includes an elongated platform supported at an elevation above ground, and a crane at each end of said platform for alignment with a corresponding end of an elongated load. Each crane has an elongated mast with a base by which it is attached to the platform for radial movement thereon between one position in which it is disposed substantially horizontally across the corresponding end of the platform and another position in which it is disposed substantially erectly at one side of the platform. A jack is interconnected between the mast and the platform and is extendable and contractable to move the mast between its two positions. The mast has a free end opposite the base and an arm attached thereto at the free end for swinging thereon between an outstretched position in which it is in substantial axial alignment with the mast and a jack-knife position in which it forms a sharply acute angle with the mast.
