Success story: From the restoration of historical machines to a career in mechanical engineering
Andreas Semmelmann and Alois Laumer have been working at SENNEBOGEN for many years and, during their training, played a key role in the restoration of historical machines that are now on display in the SENNEBOGEN Museum. Ten years after the museum opened, we interviewed the two of them. In the interview, they talk about the challenges and findings of this unique project as well as their professional development within the company.
Andreas and Alois, you were the main participants in the restoration project back then. How did the project go?
The machines were completely dismantled into individual parts, each part was restored and then reassembled. First of all, we took a close look at how the old machines worked - for example, the cable excavator, which worked without cylinders and only with cables. As soon as we understood how this technology worked, we also knew how to reassemble the machines. One of the biggest challenges was sourcing spare parts, which is why we rebuilt a lot of things in the training workshop. Although this was very time-consuming, it was also extremely instructive, as we were able to apply training content such as turning, welding and milling to real machine parts. This project was a unique experience, as it is not an everyday occurrence to be allowed to dismantle and rebuild a complete excavator during training. During this time, we had the opportunity to get to know the entire history of the company - from the simplest mechanics to fully hydraulic mobile excavators. You could hardly wish for better training!
Alois, how has your career developed since then?
After my apprenticeship, I worked on the restoration machines for another year before moving to the testing and development department. I have now been working there for over ten years. I am mainly responsible for motor installation and approval in collaboration with the motor manufacturers, as well as for the thermal management of our new battery-powered machines.
Andreas, what does your professional career look like?
After my apprenticeship, I gained a lot of experience in the assembly of large machines and was able to work on prototypes early on. I have been Section Manager for large machines since 2022 and can put my experience to good use. I have a lot of contact with my employees and am in contact with the design department in the event of problems or suggestions for improvement. I also make sure that everything runs smoothly in my department and that my people get on well.
Do you think the restoration project helped you in your career back then?
Absolutely, the project has shaped us both. Restoring the old machines gave us the opportunity to experience the company's history at first hand. Not only did we learn technical skills, but we also gained a deep understanding of the development of the machines and the company. We were particularly impressed by how simple the machines used to be. When we face complex challenges today, we often think back.
What makes SENNEBOGEN special for you?
For us, it's the family cohesion. You can talk to anyone, regardless of their position, and there is always support when you need it. And what we particularly appreciate is the variety - like back then with the restoration project. It never gets monotonous, there's something new every day and you work on impressive machines.
SENNEBOGEN for you in three words?
Familiar, flexible, large.
