PURPOSE:To improve work efficiency of transporting and carrying in various kinds of heavy goods by providing a truck capable of travelling in two directions orthogonal to each other, and mounting on the upper surface of the truck two kinds of roll units working in the direction corresponding to the moving direction of the truck. CONSTITUTION:In case of moving a truck in the direction X, a driving motor is driven, and an axle 34A is moved below a frame 10 under working of a jack 26A with a reducer, so that corresponding wheels 38, 38 are engaged with rails 12 extended in the direction X. On the othr hand, roll units 14, 14 are moved upward by working of the jack 26A with a reducer so as to transfer a metal mold onto the truck from the direction Y. In case of moving the truck in the direction Y, roll units 16, 16 are moved upward in the same manner as described above and at the same time the roll units 14, 14 are moved downward so as to transfer the metal mold onto the truck from the direction Y. |
