Mining: where loading begins.
Blocked crushers, abrasive dust, vibration around the clock — and the nearest service technician far away. We build drives that take it, and supply replacements even when not a single drawing of the legacy plant survives.
- > 1,500 kNm
- dust & vibration
- reverse engineering included
Here, every gearbox gets put through the mill.
Oversized rock blocks the crusher, abrasive dust works its way into seals and lubrication, vibration and temperature swings grind away at every drive. And because many plants sit in remote locations, every standstill turns into a logistics operation — often without a single drawing for the legacy machine that just stopped.
- Torque peaks beyond 1,500 kNm
- Dust, abrasion and constant vibration
- High shock loads from blockages and material ingress
- Legacy plants without drawings or spare parts
Built to keep working — even underground.
Our heavy-duty drives transmit torques beyond 1,500 kNm and shrug off blockages. If documentation for a legacy plant is missing, we reconstruct it.
Robust against shock and dust
Our heavy-duty drives transmit torques beyond 1,500 kNm and are designed for shock loads, blockages and abrasive operating conditions.
Reverse engineering of legacy plants
No drawing, no spare part? We survey the gearbox and deliver a fitting, often improved replica.
Emergency service for remote plants
Available around the clock, with spare-parts stocking — so one failure does not paralyse the entire extraction.
Where we are at work.
From crusher to conveyor bridge — our drives take whatever mining dishes out.
- Jaw, cone and roller crushers
- Ball and rod mills — grinding drives
- Bucket-wheel excavators and overburden conveyors
- Conveyor bridges and belt systems
- Screens, mixers and processing
- Winding and shaft hoisting technology
- Feed hoppers and stockpile conveyors
The knowledge behind the design.
What matters for drives in mining:
- a very high service factor for blockages and shock loads,
- protection against dust, abrasion and vibration,
- large torques beyond 1,500 kNm,
- replacement supply even for legacy plants without documentation.
Planning blockages into the design
Crushers and mills are regularly blocked by oversized rock. We account for these peaks with a high service factor, so gearing and bearings absorb them safely.
Sealing out dust and abrasion
Robust sealing concepts keep dust out and lubricant in — decisive for service life and maintenance intervals in an abrasive environment.
Reverse engineering for legacy plants
If drawings are missing, we measure the existing gearbox and deliver a fitting, often improved replica — with emergency priority where needed.
Service factor KA
A safety margin that accounts for the shock and overload character of the application. Shock-loaded drives (e.g. crushers, shears) require a significantly higher factor than uniformly running machines.
Torque (Nm / kNm)
The torque applied at the shaft — the central design parameter of a gearbox. What matters is not only the nominal torque, but the maximum peak torque under real operating conditions.
Reverse engineering
Reconstruction of a gearbox without existing documentation: measurement, material analysis and redesign of a fitting — often improved — replacement.
Lubrication & sealing
Lubricant film, viscosity, lubricant selection and sealing concept determine service life and maintenance effort — matched to speed, temperature, mounting position and ambient conditions.
Load spectrum
The time-based distribution of all occurring loads — continuous load, peaks, starting and shock torques. A serious design calculation works with the load spectrum, not with a single nominal rating.
Drives for Mining & Raw Materials — designed, built and tested in Marchtrenk, Austria.
Your partner for Mining & Raw Materials.
Designed for your load profile
We calculate every gearbox on the actual load spectrum and the real operating conditions of your plant — not merely on a theoretical nominal rating.
Brand-independent service
We maintain, repair and replace gearboxes from all manufacturers — including reverse engineering of legacy equipment and spare parts to original dimensions or with an improved design.
Fast support when it matters most
Downtime does not keep office hours. Our service hotline is staffed around the clock — we assess the situation, agree the next steps with you and dispatch our service technicians right away.
Engineering from Austria
Design, manufacturing and service from a single source in Marchtrenk — since 1995. Short paths, dedicated contacts, full responsibility for the result.
Frequently asked questions.
/ 01What torques do you cover in mining?+
Our heavy-duty drives transmit torques beyond 1,500 kNm and are designed for shock loads and blockages — the typical stresses of crushers and mills./ 02We no longer have documentation for our legacy gearbox — can you help?+
Yes. Through reverse engineering we survey the existing gearbox, reconstruct the geometry and deliver a fitting, frequently improved replica./ 03Do you offer service for remote sites?+
Yes. Our emergency service is available around the clock, and we stock spare parts specifically for your plant to keep downtime short.
When nothing moves, we move in.
Describe your machine and load case — or send us the legacy gearbox without any papers. We measure it, recalculate it and deliver what holds up.
