PROBLEM TO BE SOLVED: To simplify reversing work for a truck frame. SOLUTION: As one side beam of the truck frame placed on a movable side beam support 9 remains placed on the side beam support 9, another side beam placed on a fixed side beam support 6 is lifted up by a crane. At the same time, the movable side beam support 9 is moved, followed by reversing the truck frame and placing one side beam lifted up by the crane on another fixed side beam support 7. In the state that one side beam of the truck frame is placed on the movable side beam support 9 at all times, the truck frame can be reversed, permitting more stable reversing work than reversing the whole truck frame after lifted up.
