PURPOSE:To obtain easy transportation of a heavy article with simple construction and without being restricted by transportation road conditions by making a traveling truck movable up and down via a revolving device and making a traveling girder get away from the ground via a wheel. CONSTITUTION:A heavy article is placed on a traveling truck 3 with a cylinder of a hydraulic jack up device 2a extended, and weight of the heavy article is transmitted to the ground via a receiving board 2. At this time, ascent of a wheel 3b produces a state in which a traveling girder 1 is hanging down from 3b via a guide hardware 1b. Next, as the wheel 3b rotates, the truck 3 advances as it hangs the traveling grider 1. Change in the direction of advance is made by driving a turning device 3c. Next, the hydraulic jack up device 2a is contracted so that the traveling truck 3 is placed on a rail 1a installed on the girder 1, and the truck 3 advances by means of the wheel 3b. With reiteration of this operation, the article can be transported easily without being restricted by road conditions. |
