To easily carry and install equipment, eliminate the need for other carrying and installing implements and reduce burden on work.

A rectangular frame 1 is formed by vertically and laterally supporting poles 2, 3 and a plurality of supporting pawls 4 are mounted on the frame 1. Equipment is placed and fixed onto the frame 1 with the supporting pawls 4. Hydraulic jacks 9 are mounted at the corners of the frame 1 and casters 10 are mounted on the hydraulic jacks 9. The vertically or laterally supporting poles 2, 3 are split into two parts, at central portions of which screw rods 7 having expansion handles 6 are laid. When the screw rods 7 are rotated, the frame 1 is expanded to the longitudinal and cross directions. A pair of right and left carriage handles 11 are mounted on the upper face of the vertically supporting pole 3. The legs of the casters 10 are expanded up and down by the drive of the hydraulic jacks 9 and the frame 1 is expanded or inclined in association therewith. In carrying and installing the equipment, the carriage is freely moved up and down with the area of the frame modulated depending on the size of the equipment. Therefore, serial carrying and installing work can be performed with one carriage.
