Precision work at the Luterbach hydropower plant honoured
Senn AG took second place for crane work under 120 tonnes at the awards ceremony of the German Federal Association for Heavy Transport and Crane Work (BSK). The award is based on various crane projects, such as the overhaul of the Luterbach hydroelectric power plant, which Senn carried out in 2025.
Senn AG from Oftringen, which specialises in steel and metal construction as well as crane and other transport, took second place for Crane Work of the Year 2025 under 120 tonnes at the BSK Annual General Meeting on 12 October. The company was nominated in several categories with challenging projects.
According to a press release, the basis for the award is the overhaul of the Luterbach SO hydropower plant, which Senn carried out together with ADEV. As part of the project, a 20-tonne generator with a height of 3.5 metres and a 3.4-metre turbine wheel had to be removed from the hydroelectric power plant, transported, overhauled and finally reinstalled. Lifting the generator and turbine wheel through a roof opening in the power station required millimetre precision work from the crane operators. A specially designed steel frame and a customised heavy-duty transport solution then ensured the smooth removal to the overhaul plant.
The Luterbach project is an example of the company’s own combination of engineering skills, precision and experience in heavy haulage, which enables successful project execution, explains Senn AG.
Senn AG operates in the fields of steel and metal construction, sheet metal and stainless steel centres, emergency power systems, cranes and transport. With more than 200 employees, the company claims to be one of the most important employers in the Zofingen district.
