Abstract

PURPOSE:To make the supporting loads of both wheels equal and stabilize the macine body by supporting wheels with separate buffering mechanisms, and arranging each cylinder between wheels and buffering mechanisms and allowing these cylinders to displace in the direction where the wheels are moved up and down, by selector valves. CONSTITUTION:When a machine body is tilted leftward, the supporting load for the right wheel 96 decreases and the supporting load for the left wheel 9a increases. In this case, the right wheel 9b descends against the machine body, allowing the buffering mechanism 30b to displace frontwards. As a result of front ward displacement of the buffering mechanism 30b, a right selector valve 35b which is linked with the buffering machanism 30b is switched so as to feed oil pressure to the front chamber of a right hydraulic cylinder 22b, and the right wheel 9b is moved upward by the action of the hydraulic cylinder 22b, and the left side is operated reversely and moves downward. Thus, the machine body is returned so as to be in horizontal state, and when the supporting loads of both wheels become equal, both selector valves 35a and 35b are brought into neutral plsition, and cylinders 22a and 22b stop operation.
