On-Site Line Boring for Mining Equipment

BOS portable line boring machines repair worn bores on rope shovels, draglines, mining excavators (20T–100T+), stone and jaw crushers, dump and haul trucks, loaders, dozers, and conveyor or processing equipment — anywhere a cylindrical pin bore, bushing housing, or shaft bore has worn oversize or oval.

A typical on-site bore repair on a mining excavator takes 4 to 8 hours from setup to completion, compared to 5–10 days for conventional workshop repair once transport, dismantling, and workshop queue time are included.

The BOS-DS60 is recommended for most mining applications. Its 65–600mm bore range, 3800W motor, and 220 N.m torque handle the large pin bores, crusher eccentric shafts, and swing bearing housings found on heavy mining equipment. The BOS-DS50 (55–160mm) suits smaller support equipment and standard loaders.

Yes. BOS machines run on standard 220V or 380V power and are generator-compatible — a 5–6 kVA generator is sufficient — making them fully deployable to remote open-cut mines and sites without permanent power infrastructure.
