Design and Manufacturing of a Backup Roll Lifter for the Steel Industry

Backup Roll Lifter for Steel Industry
 

A steel manufacturer required a lifting device to handle their backup roll assemblies safely and hands free. The design required a single lifting device to lift the top assembly, the transfer stool, and the bottom assembly. The bottom assembly had to be removed from a pit with minimal clearance.

Hunter Lift determined that a standard backup roll lift device was suitable for lifting both the upper and lower assemblies. A secondary set of lifting feet were included to lift the transfer stool. These additional lifting feet can be pinned up and out of the way of the backup roll assemblies for operation of the standard backup roll lift. Hunter Lift supplied the customer with drawings to modify their stool and allow for the addition of the lifting feet. The backup roll lifter was fabricated to lift up to 160,000 lbs. The unit was delivered to Indiana for installation and operation.
