However, the above-described conventional heavy load reversing device has the following problems. That is, in addition to the installation space for the heavy load reversing device,
A space is required for putting the heavy load 400 into and out of the drum 600. On the other hand, if an ordinary heavy object overturning device is used, a space for putting the heavy object 400 in and out of the drum 600 is not necessary, but as shown in FIG. 9, a complicated procedure, that is, the heavy object 400 is overturned by 90 °. (See FIGS. 9A to 9C), the heavy object 400 is hung up to
It must be rotated horizontally by 80 ° (see FIG. 9 (D)), and then the heavy object 400 must be overturned by 90 ° again. Therefore, there is no need for a space for putting the heavy object in and out of the drum 600, but multiple steps such as hanging the heavy object with a crane are required. Therefore, the surface of the heavy object may be damaged.

The present invention was devised in view of the above circumstances, and it does not require a space for putting in and out a heavy object, and further, there is no fear of damaging the surface of the heavy object, and continuous inversion can be performed. It is an object of the present invention to provide a heavy load reversing device that can reduce the time required for.
