12) to operate the cylinder (12), the truck (1) is not equipped with a large-scale compressed fluid supply device, and the frame (3 ) is hollow, and by using the compressed fluid stored inside it, it is possible to raise and lower the conveyed object mounting table (4) with an extremely simple device. The worker carries the lower parts on a trolley (
1) It can be installed with great ease of operation, speeding up production lines for automobiles, etc., and improving efficiency. Moreover, the hollow frame (3
), it is possible to reduce the weight and size of the trolley (1), as well as to prevent fire accidents from occurring in, for example, the paint booth of an automobile production line. Yes, it is very safe. Moreover, since the means for supplying fluid pressure to the cylinder (work 2) is simple, the equipment cost is extremely low.
