Underwater Excavation with Drum Cutters
Underwater excavation is one of the most demanding tasks in construction and foundation engineering. Limited visibility, high water pressure, and hard geological layers require equipment that combines strength with reliability. Traditional breaking methods often face difficulties in submerged conditions, resulting in higher costs and lower efficiency.
Hydraulic drum cutters have emerged as a practical solution for underwater excavation, trenching, and foundation work. Their ability to provide precise cutting, low vibration, and stable performance makes them well suited for these challenging applications.
Wolver BM95 in Action
In this project, the Wolver BM95 hydraulic drum cutter was used for underwater foundation excavation. Thanks to its high torque output and robust construction, the BM95 was able to cut through rock layers effectively even under extreme working conditions.
