IMPROVEMENTS RELATING TO APPARATUS FOR TRANSPORTING LOADS

Details are given of an invention to transport loads on difficult terrain by means of inflatable elements arranged laterally. The elements are tubes of flexible material arranged to collapse when deflated so that their lower walls are raised clear of the ground when not in use. The apparatus creates a series of waves, caused by successive inflation and deflation of the tubes, and these waves progress across the whole undersurface of the device and result in a progressive movement relative to the ground of an attached sheet or board composed of a light alloy or reinforced plastic material. /TRRL/
