When it comes to gold mining operations, few machines work harder or endure more abuse than the underground loader. Designed for low-clearance environments, high dust exposure, and constant cycling of heavy loads, these machines are vital to production. But when one fails—especially deep in the drift—a full replacement isn’t always feasible. That’s when a well-planned, field-tested underground loader rebuild becomes the smartest solution.
This case study explores how Industrial & Mining Services (IMS) was called to perform a full mechanical and structural rebuild of an underground loader used in a mid-sized gold mine in Northern Georgia. The project involved teardown, part remanufacturing, frame crack repair, hydraulic reseal, and full component testing—all completed underground to reduce downtime.
The client operates a mid-level gold mining facility processing 600 tons of ore per day. Their primary Sandvik LH514 underground loader had begun to fail after 16 months of continuous use. IMS was called to restore it to working condition without surface hoisting.
IMS deployed a 3-person underground crew with mobile tooling. Key inspections included:
To avoid costly surface transport, IMS planned a full underground rebuild. Primary goals included:
Components removed included the bucket, boom pins, pump, and articulation joint. Weld repairs featured:
IMS serviced the following components underground:
Phase | Days | Task |
---|---|---|
Phase 1 | 2 | Disassembly and structural welds |
Phase 2 | 3 | Mechanical overhaul |
Phase 3 | 1 | Reassembly and function testing |
Industrial & Mining Services offers:
“IMS rebuilt our LH514 underground in just days—no delays, no excuses. Their field crew knew what to do the moment they arrived and delivered a flawless rebuild.”
— Mine Foreman, Northern GA Gold Operation
