Summary

Location Austria
Dredging depth 45 m
Production 4.2 m3

After 21 years of continuous operation, it was time to replace the old dredger with a new, more powerful machine. The machine also had to take into account stringent environmental regulatory requirements and the shorter annual operation period. A 4.2 m³ grab dredger was specially designed for use in the Raggal reservoir with several state-of-the-art components.
