Large weld safety procedures were updated on September 23, 2015 for Cat Forest Products in Prentice, WI. The document outlines the tooling design and development process for Cat products, including reviewing part drawings for critical quality aspects, datums, manufacturability, and tolerance stack-up studies to implement into tooling design. Photos show the removal and flipping of a lower frame part using a bridge crane before being sent to a boring bar machine.
