Cutter head

For one cutter head, there are 6 blade, 7 teeth equipped on one blade. There is material Cr. for easy-wearing proof.

The most important parts of cutter suction dredger and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire cutter suction dredge. Lateral traction winches, lifting winch and cutter head of the dredgers are driven by hydraulic motors.

Cummins engine

Testing equipped on the discharge pipeline on the cutter suction sand dredger boat. The cutter suction sand dredger boat has Cummins engine and hydraulic system for easily operation.
