PROBLEM TO BE SOLVED: To improve travel stability on a sloping ground in a crawler type lorry. SOLUTION: The lorry comprises a crawler device 2 for travel, a steering wheel 10, and a loading platform 3 on a frame 1. The loading platform 3 is formed by disposing a slide platform 31 longitudinally slidably and positionally on a base 11 having a bracket 12 for supporting the crawler device 2. When the lorry travels on an uphill slope, the slide platform 31 is moved forward. The center of gravity of a cargo on the slide platform 31 moves in the forward travelling direction of the lorry, so that the travel stability of the uphill slope can be improved. When the lorry travels on a down slope, the slide platform 31 is moved backward and the center of gravity of the cargo is moved backside, the travel stability can be improved.
