Precision Bore Repair for Rotary Drilling Rig Critical Structural Components
Release Time:
Sep 08,2026
Our workshop has delivered comprehensive structural overhaul for a heavy‑duty rotary drilling rig. Suffering from long‑time piling operations, the boom hinge bores suffered wear and oval deformation. Our technicians adopted portable line‑boring machine for on‑site machining, restoring dimensional tolerance. Full‑range inspection on boom, track undercarriage and hydraulic circuits further secures stable performance for future heavy‑load jobs.
A large rotary drilling rig is undergoing thorough structural maintenance in our workshop. Continuous heavy‑load piling work brought wear and oval distortion to boom hinge points. Excessive clearance at pivot joints may lead to shaking and abnormal stress during operation, threatening both working efficiency and equipment safety.
Our technicians operated portable line‑boring equipment to carry out in‑situ machining. Damaged metal material was precisely removed while aperture and coaxial tolerances were strictly calibrated. Alongside boring work, the full boom assembly, track system and hydraulic hoses were thoroughly inspected to eliminate potential defects.
Hinge bore wear is a typical failure for large rotary drilling rigs. The on‑site line‑boring solution avoids cumbersome component disassembly, balancing repair cycle and cost. After repair, structural matching accuracy reaches near‑OEM level, enabling the machine to handle demanding piling projects again.
