Line Boring Machine with Welder

Our mobile line boring machine with welder is engineered for on-site repair of worn pin and bushing bores in construction and mining equipment.

With the integrated system precision bore welding with accurate portable line boring, the damaged bores can be rebuilt with the boring welding system and machines them back to OEM tolerances without removing large components.

Designed for in field service, the machine ensure that shop-level machining can be fulfilled accuracy directly at the job site, even in demanding construction and mining environments.

All construction and mining operators is capable of minimizing downtime by using Portable line boring and welding machines, reduce repair costs, and extend equipment service life.

On-site bore repair solution makes everything possible, avoiding the need of disassembly, avoiding costly replacement, and avoiding long time waiting for repair in the machine shop.

By restoring worn bores instead of replacing major components, our customers can achieve faster turnaround, lower maintenance costs, and improve the reliability of damaged equipment. Keep critical equipment productive and profitable.

Our portable line boring machine with welder provides versatile on-site machining capabilities, including:

• On-site line boring for worn pin and bushing bores
• Bore welding for rebuilding oversized, elongated, or cracked holes
• Precision machining of coaxial bores with high alignment accuracy
• Repair of boom, arm, stick, bucket, and linkage pivot points
• Field machining in confined spaces or remote mining locations

These capabilities make portable line boring and welding machines ideal for heavy-duty equipment repair where the traditional machine tools are impractical.

Portable line boring and bore welding machines are widely used in maintenance of construction and mining equipment, including:

• Excavators
• Hydraulic shovels
• Backhoes
• Wheel loaders
• Bulldozers
• Motor graders
• Various trucks like haul trucks and dump trucks
• Articulated vehicles
• Buckets, booms, arms, frames

With wide range of applications, on-site line boring machine with welder is an essential solution for on-site equipment repair, rebuild, and life-extension in construction and mining equipment.
