PROBLEM TO BE SOLVED: To provide an inexpensively providable strong work truck capable of ground travel and track travel, by using simple lifting means of a scaffold board.SOLUTION: A work truck 1 comprises a truck body 2 having a base 4 and a column 5 and a scaffold board 3 supported in an optional height by the column 5. The truck body 2 comprises a front steering wheel 6, a rear driving wheel 7 and a steering shaft 8. The steering wheel 6 and the driving wheel 7 comprise grounding wheels 31 and 34 for respectively traveling on the ground surface and track wheels 32 and 35 for traveling on a track. The steering wheel 6 can be fixed in a straightly-advancing state. The work truck 1 travels on the ground surface by steering by the grounding wheels 31 and 34. A rear part of the truck body 2 is lifted by gripping a hand-push handle 12, and can move on the ground surface or the track by manpower by the steering wheel 6 fixed for straightly advancing.SELECTED DRAWING: Figure 1
