It is possible to move between racks and to hang a rack etc. on the hanger part while staying downstairs, and to move the rack etc. to the hanger part on the upper floor such as the mezzanine floor where the multi-row storage device is installed. Since it can be stored in a hanging state, the product and equipment can be stored efficiently and workability can be improved. (2) By installing a multi-row storage device on the upper floor such as the mezzanine floor, it is possible to store products and equipment on the upper floor such as the mezzanine floor while the rack is attached to the hanger. It has the effect of being able to effectively use the space on the mezzanine floor of factories and warehouses, as well as the limited space on the site. (3) Since products and equipment can be stored and taken out simply by rotating the arm, there is no need for humans or robots to move the products or equipment to store or take out, as in the past. As a result, it is possible to significantly save labor and to reduce the cost of the storage equipment. (4) Since products and equipment can be stored by a rack or the like hanging on the hanger part, it is easy to grasp the storage location of the products and equipment, and the workability is excellent. (5) Since the balance part is rotatably suspended around the support shaft, the weight balance is always maintained and the balance part is stationary, so racks of various weights can be hung on the hanger part, and storability is improved. It has the effect of being excellent. (6) Since the hanger part is rotatably hung around the hook shaft, the rack where the products and fixtures hanging on the hanger part are stored always has a multi-row storage device installed on the floor. Since it is kept perpendicular to the parts, the product etc. can be prevented from falling and falling, and the product etc. can be stored in a rack etc. without being specially fixed. (7) The weight of a rack or the like in which the products and equipment hooked on the hanger are stored by rotatably supporting the support frame on the arms and the support shaft on the support frame. Accordingly, the support frame can be rotated according to the situation, weight balance can be always maintained, and products and equipment can be stably stored. (8) By supporting many hook shafts in a straight line below the balance part, racks can be stored in multiple rows, so a large variety of products and equipment can be stored in racks etc. by type. In addition, it has the effect of improving the efficiency of storage and storage of stored items. (9) By providing the counterweight from the base of the arm to the back side, when rotating the arm, the weight of the arm etc. can be reduced by the weight of the counterweight on the back side of the arm. This has the effect of saving labor and downsizing the drive unit.
