Mobile formwork for the construction of a road tunnel

For the construction company Skanska, we designed and manufactured a special mobile formwork structure for the concreting of a 400-meter road tunnel near Oslo, Norway. This massive metal structure, weighing 250 tons, consists of approximately 70,000 parts and reaches a width of 20 meters and a height of 6 meters. The formwork was designed to allow smooth movement as a compact unit, which accelerates the concreting of individual tunnel blocks with a rectangular profile, often used in urban areas for elevated transportation. After completing production at our Opava facility, a trial assembly was conducted, and all hydraulic functions of the equipment were verified, including training for the customer's workers.
