PROBLEM TO BE SOLVED: To safely and efficiently perform direction changing and track changing by a small number of workers. ;SOLUTION: A support cylinder 20 is provided in the center of gravity of a truck 6 so as to penetrate the upper and lower sides of the same. A support shaft 30 having an operation rod 31 in an upper part is fitted to the support cylinder 20 so as to be moved up and down, a grounding member 32 is attached to the lower end of the support shaft 30, and the base plate 33 of the grounding member 32 is provided to be rotated against the support shaft 30. A stopper 40 is provided in the support cylinder 20, the base plate 33 of the support shaft 30 is locked in an upper specified position during disuse and, during use, engagement with the support shaft 30 is released to permit the up and down movement of the support shaft 30. Also, a swing arm 48 is provided in the support cylinder 20, the up and down movement of the support shaft 30 is permitted during the operations of operation levers 46 and 46 and, during non-operations, it is locked in the support shaft 30 to permit the lower displacement of the support shaft 30 to the truck 6 and prevent the upward displacement of the same. At the time of direction changing for the truck, by the operation of the operation lever 46, the support shaft 30 is lowered to ground the grounding member 32 and, by turning the truck 6, direction changing is performed.;COPYRIGHT: (C)1999,JPO
