Where our drives run

01

Hot rolling mill

A steel plant replaced six aging reducers with HG-H120 units on the same foundations and halved unplanned stops in the first year.

02

Cement kiln

HG-C cardan drives turn a 4.2 m kiln around the clock, with oil changes once every 12 months.

04 / FAQ

Questions buyers ask

01Can you match the footprint of our current gearbox?

Yes. Send us the old drawing or measurements and we build to the same shaft heights and bolt pattern.

02Do you service gearboxes on site?

Our field engineers inspect, realign, and replace bearings on site. Most visits are scheduled within a week.
