Our process to the special gearbox - explained step by step.


Your first contact or inquiry comes to us by e-mail, by phone, by visiting a trade fair, etc..

An initial consultation and data transfer takes place. We advise you on your requirements: either for a standard gearbox or for a customized gearbox.
If a new project arises, a non-disclosure agreement can be signed at your request.
We go into the second intensive consultation with you, exchanging ideas & suggestions based on examples and, if necessary, giving a first estimate on costs, project duration and delivery time.
You decide on your optimal solution.
You commission the official project. As a rule, you will only incur costs from this point on!
The development phase starts in close cooperation with you. Your project manager and the development department stay in close contact with you.
Within a third intensive consulting phase you will receive your final product offer including costs and delivery time.
You then order and receive your gearbox sample.
With the sample or prototype, the gearbox is tried and tested on your premises or at ours.
Afterwards we start the pre-series and the field test.
If there are changes and adjustments, we go into a re-design.
After that, the official series production or your frame orders start.
Our service and after-sales team is still there for you after the development of your special gearbox and advises you on all questions.
