Abstract

PURPOSE: To rearrange rolls safely and quickly while hanging a main body, by lifting an inside roll unit together with the main body of the machine and lowering the main body to the position of the new roll unit after separating said unit.
CONSTITUTION: A wire of the crane is engaged with the hook, and a main body 7 of the machine fitted with a roll unit 4 is lifted by the crane, and it is moved as it is to the off line of a frame 24. Here the bolts and nuts are removed from the main body 7 which is being hanged by a crane and the unit 4 is separated from the main body 7. Then the main body 7 is lifted with the crane and horizontally moved to the position of the new roll unit 4' and the main body 7 is lowered on the new roll unit 4' to connect and both are aligned to be fastened and jointed together. Afterward the main body 7 fitted with the new roll unit 4' is transfered to the on line with the crane to place it on the longitudinal beam and the rearranging is completed after fixing it.
