    • PROBLEM TO BE SOLVED: To transport handling materials not less than an optional position among a large number of stacked handling materials by constituting a subject device of a support body, arm bodies, a gripping-holding cylinder and claw bodies, and arranging the front and rear claw bodies to particularly grip and hold front and rear surfaces of the handling materials on the lower side of both arm bodies. SOLUTION: A cargo handling vehicle is moved so as to travel toward handling materials stacked in large numbers, and is positioned between front and rear arm bodies 3 above the handling materials. Next, a raising-lowering body 52 of the cargo handling vehicle is lowered, and front and rear claw bodies 5 are opposed to each other in the front and rear vicinity of the handling materials to be gripped and held. Afterwards, when a front gripping-holding cylinder 4 is actuated, the front arm body 3 is moved backward, and when a rear gripping-holding cylinder 4 is actuated, the rear arm body 3 is moved forward, and front and rear surfaces of the handling materials are gripped and held by the front and rear claw bodies 5. When the raising- lowering body 52 is raised, the handling materials gripped and held by the front and rear claw bodies 5 and handling materials stacked on these are raised together, and these are carried by travel of the cargo handling vehicle.
