Soft impact grab dredger
Safety structure removal and dredge work in underwater mines remaining water area
Large-scale soft impact grab dredger
Harbor construction work in underwater mines remaining water area is still dangerous even years have passed. The system "soft impact grab dredger" is developed as the construction system that enables safety structure removal and dredge work in underwater mines remaining water area. Even the machine directly grabs hidden underwater mine, there is no risk of giving direct impact to the mine by the function of its hydraulic mechanism, which enables safely operation in dangerous area.
Actually, the machine gripped a mine in the dredging work area at right bank of the Shinano river in August 18th 1994, but the machine successfully salvaged it in safety. Our office advanced further development of large scaled unit of this soft impact grab dredger for safety and effective dredging operation in large volume.
