About Us


We were founded in 2008 with support of the German Engineering company Gelus GmbH. We started with the overhaul of wind turbine gearboxes and smaller industrial planetary gearboxes.


Now we continue with the engineering and assembly of new gearboxes especially planetary gearboxes in small and midsized series. We have close cooperation to specialised industrial gearing companies.


We have good and experienced network of suppliers. All our employees are well experienced and worked before at a wellknown gearing company.

Our work in more detail


We provide the service of all industrial gearboxes including overhauls, damage rectifications and offering the optimal solution for complete service actions.

Spare parts

We are able to offer you: the gearbox repairs without being dependent on the original manufacturers. Thanks to our experience and skills especially in the field of reverse engineering we are able to create documentation in 2D and 3D CAD.

Delivery of new gearboxes

We provide: own standard gearboxes, especially planetary gearboxes, but also general-purpose spur and bevel gearboxes according to our customer´s request.

Special adaptations of gearboxes

We design and construct special parts for industrial applications upon your request. We often construct frequently requested gears as reconstructions for discontinued model series but produced with modifications due to changing requirements (such as torque, power, speed etc.).
We also provide the new construction of gears with identical connecting dimensions and this is the part of our range of services: whether it could be as a replacement for defective gears or as an additional spare item.
