Mining Gearbox Overhaul

Mining Industry Gearbox Overhaul & Inspection

Mining operations run under some of the most demanding mechanical conditions on earth. Extreme shock loads, continuous operation, harsh environments, and remote locations make gearbox reliability absolutely critical. When a SAG mill, ball mill, crusher, or conveyor gearbox fails, production stops — and in mining, every hour of unplanned downtime carries enormous cost.

Hedberg Technical Services delivers professional on-site mining gearbox overhaul, inspection, and condition assessment for mining operations worldwide. We come to you — no matter where your mine is located — and perform the work on-site to minimize downtime and get your equipment back in production as fast as possible.

FAQ

Can you work on SAG mill gearboxes on-site without workshop facilities?

Yes. We bring all necessary tooling, precision measuring equipment, and technical expertise directly to your site. We have the capability to perform complete overhauls on large mill gearboxes in the field.

What gearbox brands do you service in mining?

We work with all major industrial gearbox manufacturers commonly found in mining operations, including Flender, Renk, Hansen, David Brown, SEW, Brevini, and others.

How quickly can you mobilize for an emergency breakdown?

Contact us immediately with your situation and location. We prioritize mining breakdown calls and work to mobilize as fast as possible. Response time depends on location and logistics, but we move urgently for unplanned failures.

Do you service gearboxes in remote or underground mining operations?

Yes. We are experienced working in remote locations and challenging environments. Contact us to discuss your specific site conditions.

How often should mining gearboxes be inspected

At minimum, a detailed inspection and overhaul should be planned during annual extended shutdowns. For high-load equipment like SAG mills and crushers, more frequent condition checks are recommended based on operating hours and oil analysis data.
