When installing/removing the feed roll, you have to lift the heavy roll to a high position, which is extremely difficult, especially for larger machines. In addition, if dropped accidentally, not only could feed roll damage occur, but the operator could be seriously injured.
The safe roll hanger (Utility Proposal registration: No. 3231696) was developed to prevent the feed roll from falling thus resulting in an easier change over.
Connect the hook block of the hoist crane to the safe roll hanger.
Take the feed roll which is kept on the feed roll storage shelf, lift it up through the upper support arm of the safe roll hanger and move it to the feed roll section.
Perform positioning by fitting the connection bar to the feed roll box, and push the feed roll in to set it.
In the case of removing the feed roll from the machine, the procedure will be the reverse.
