As we mentioned in a previous post, Mill Roll handling can be a difficult task, given the complexity and variety that comes with the application. Performing this operation safely and efficiently should be a top priority for any Rolling Mill.  In this post, we’ll cover some of the mechanically operated equipment options Bradley offers for this application.

Automatic Tongs 

Automatic tong style units offer a large variety of handling options – a tong can be designed to handle by the roll body, the roll ends, or by the chocks via engaging lifting openings. 

Automatic tongs allow hands-free operation, with little or no operator assistance. The lifter securely grips the load with vertical motion from the crane, therefore it is failsafe by design.

An additional benefit of a mechanical device is that the hands-free operation comes without the added need for an external power source. 

Some of the drawbacks of a mechanical device are: 

  • The limited load variety, in that a single tong can only handle a certain range of load sizes. 
  • A mechanical tong is typically heavy, especially compared to a beam or lifting frame for the same load size. 
  • Finally, the added concern, if called for by the process, of gripping a roll by its body. This can introduce the possibility of damage to the roll surface. If possible, the easiest way to mitigate this issue is to lift by another part of the roll, such as its ends.

While there is a limit to the range a single tong can handle, application-specific devices can allow you to handle rolls in unique and potentially safer and more efficient ways.
