Pro Line Machining LLC

When your mining shovel sits idle or a dragline boom cracks, every hour ticks away in lost production revenue. You don't need a vendor that shrinks from a challenge-you need a partner equipped to scale up.

At Pro Line Machining, we don't think in terms of limits. We think in terms of solutions.

We just finalized our updated Capabilities Booklet to give your procurement and operations teams an inside look at how we handle the heaviest structural and mechanical demands in the region.

Swipe through the photos below to see our core divisions in action:

Field Services: Rapid, turnkey mobile machining deployed directly to your site 24/7/365.

Certified Welding: Heavy structural rebuilds, severe-wear skinning, and complete lip replacements built to last.

Precision Line Boring: On-site bore restoration that brings severely worn industrial housings back to strict OEM tolerances.

Heavy Fabrication Complex: A massive, crane-serviced facility in Gillette, WY, built to receive, rig, and process oversized iron.

From emergency field repairs to major shop overhauls, we manage the heavy logistics so you can focus on production.

Zero Excuses. Uncompromising Precision.

Sometimes you just have to step back and appreciate the view. Open skies, massive steel, and precision engineering right in the dirt.

We love what we do.

Wear and tear on a Bucyrus 2570 dragline requires specialized, large-scale solutions. We have a project underway to overhaul the drag system and restore critical mechanical integrity to this asset. Our field technicians are machining the drag drum bores, drag cases, and all four gearcases directly on the machine, ensuring perfect alignment and precise tolerances.

By restoring these heavy-duty housings on-site, we help our client optimize gear contact, eliminate harmful operational vibration, and extend the operational life of this mining giant.
