PROBLEM TO BE SOLVED: To eliminate a vehicle body stabilizing mechanism such as an outrigger, make a vehicle weight light and assure its mobility by eliminating a tire for use in dampening an input from a running road surface, the dampening function of a suspending device when a cargo or the like is hung with a boom and stabilizing the vehicle body with respect to the ground surface. SOLUTION: There are provided an air suspension having the function of dampening an input from a road surface by an inner pneumatic pressure, a core formed by hard resin inserted into a tire and an air pressure controller for use in adjusting an air suspension and a pneumatic pressure in the tire. With this arrangement as above, the vehicle body turns from a halt as it remains ready for running into the state that air pressure decreases with the air suspension and air in the tire released by an air pressure controller, the vehicle body eliminates a spring element with respect to a ground surface to enable an oscillation of the vehicle body caused by a motion of the boom and the like to be restricted and then a cargo hanging-down state can be attained with the boom.
