Taking the machine shop straight to the field!

A quick look at the crew setting up to machine a hoist pedestal pad for a Bucyrus 495BE electric shovel. We milled the pad flat, relocated all the mounting holes, and drilled them out to restore perfect alignment.

When the iron is this big, you don’t pull it apart and ship it, you bring precision machining directly to the dirt.

Building it back up to cut it back down. When heavy equipment bores get ovaled out or worn down from extreme use, you can't just slap a new part on. You have to rebuild the steel from the inside out.

This is our automated bore welding setup in action. We lay down precision layers of high-strength weld inside the housing, prepping it perfectly so our field boring bars can cut it back to exact factory dimensions.No shortcuts. Just flawless material restoration. Got a piece of equipment that's losing its tight tolerances? Bring it to Pro Line.
