Abstract: A pontoon assembly for floating bridges includes four pivotally interconnected articulable floats providing a pontoon assembly having a folded and an unfolded position. Each of the floats is generally rectangularly shaped. In the unfolded position the pontoon assembly has an inner two floats and an outer two floats and the outer two floats are lengthwise connected to an outer edge of the inner two floats. The inner two floats each have an upper surface which provides a vehicular roadway. A rectangular recess is disposed in each of the outer two floats and the recess has a size sufficient to permit a ramp part to be removably positioned in there. The ramp parts have a height corresponding to the depth of the recess in order to provide a flush upper surface with the upper surface of the associated outer float. Each of the ramp parts includes lugs to permit connection with an inner float to thereby provide a closed rampway.

Abstract: A motor vehicle for transporting and laying a fixed bridge includes a ground supported vehicle having a chassis with a front and a rear. The slide frame is longitudinally displacably mounted to the chassis and has a first travel position and a second extended position wherein a first end of the slide frame is disposed a substantial distance from the rear. A support leg is secured to the first end and includes a ground engaging portion extending beyond the lower surface of the slide frame and supporting the slide frame. A bridge member is carried by the slide frame. A bridge member laying and displacement device is connected generally to said first end and includes a rearwardly extending portion adapted for supporting the bridge member during displacement thereof.
