Steel & metals: Heat. Load. Shock.
Rolling shocks, radiant heat, mill scale, reversing every few seconds — few environments wear out a drive faster than a steel mill. We design gearboxes for exactly these loads, so your line keeps running when it counts.
- Shock and alternating loads
- High ambient temperatures
- Continuous operation
Here, shock loading is the normal case.
Rolling stands, scrap shears and converter tilting drives hammer load peaks into the drivetrain with every pass — peaks that age a gearbox selected by nominal rating well before its time. And when it fails, it is not one unit that stops but the whole line behind it — amid heat, mill scale and running production.
- Impact and shock loads far above the nominal load
- Radiant heat, mill scale and dust at the drive
- Reversing and starting torques every few seconds
- Downtime costs of thousands of euros per hour
Designed for the most demanding operating conditions.
We calculate with what actually arrives in the mill: the real load spectrum, shock peaks included — not a nominal rating from a catalogue. Built in Marchtrenk, serviced brand-independently.
Calculated on the load spectrum
Shock peaks, reversing operation, load reversals and starting torques flow into the design — for drives that withstand plant reality with safety reserves.
Hot, dusty, continuous
We match materials, sealing systems and the lubrication concept to temperature and mill-scale ingress — so service life does not end at the seal.
Service that prevents downtime
Inspection, repair, retrofit, 24/7 emergency service — brand-independent, on site within the DACH region in under 24 hours.
Where we are at work.
We know the drives of heavy industry — and their load profiles.
- Rolling stand and continuous casting drives
- Crane systems for converters, ladles, coils
- Scrap shear, slab and forging drives
- Sintering and pelletising plants
- Conveyor and reel drives
- Converter and ladle tilting drives
The knowledge behind the design.
What matters for drives in the steel and metals industry:
- a high service factor for shock and peak loads,
- resistance to temperature and mill scale at the installation site,
- a robust design for reversing and continuous operation,
- fast spare-parts and emergency supply.
Applying the shock factor correctly
Rolling stands, shears and tilting drives generate load peaks far above the nominal load. Shock and load spectra are accounted for in the design of gearing, bearings and shafts.
Heat, mill scale, continuous load
We match materials, sealing systems and the lubrication concept to radiant heat and to the dust and mill scale at the installation site.
Brand-independent service
We maintain, repair and retrofit gearboxes from all manufacturers in your plant — including reverse engineering and spare-parts manufacture to original dimensions.
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.
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.
Reversing operation
Frequent change of rotation direction. It stresses gearing and bearings particularly hard through load reversals and must be specifically accounted for in the design.
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.
Retrofit
Modernisation or general overhaul of an existing drive instead of buying new — often with an improved design and shorter delivery time.

Frequently asked questions.
/ 01Do your gearboxes withstand the shock loads in a rolling mill?+
Yes — because we design for the real load spectrum, including shock peaks and reversing loads, and dimension the critical points accordingly. That is exactly what ATP heavy-duty gearboxes are made for./ 02Do you also service gearboxes from other manufacturers in our plant?+
Yes, our service is brand-independent. We inspect, repair and retrofit drives from all manufacturers — including spare-parts manufacture to original dimensions./ 03How quickly are you on site after a failure?+
Our emergency service is available around the clock; within the DACH region we are on site in under 24 hours to keep downtime as short as possible.
