The cutter suction sand dredger is a stationary dredger equipped with a cutting device, which excavate the sand and soil before the slurry is sucked up by the dredge pump.

Hull without propulsion means / optional with propulsion equipment (small size can also meet propulsion). Self-propelled, specially designed ocean-going hull. No matter whether the cutter suction dredger can self-propell, it needs to fix the position with a positioning pile before it can start work. A cutter head is a mechanical rotating tool that can cut hard soil or rock into pieces. The winch pulls the winch by pulling the winch to make a fan-shaped movement, and the rotating cutter head can enter the water and swing in the soil. It is installed in front of the suction head, and the soil and rock cut into fragments are sent directly to the mud treatment area through the powerful suction of the dredging pump.

For specific types of soil, OCEAN Pump will design different cutter head heads. Because different soils have different hardness and different viscosities, the cutter head heads that need to be used will be different.

It should be noted that the cutter teeth need to be replaced, because dredging in hard soil will cause it to wear out.

The cutter suction dredger equipped with propulsion means can carry out long-distance travel and is used flexibly all over the world.

Small and medium-sized cutter suction dredgers can be disassembled and transported on land.

It should be noted that the cutter suction dredger is very sensitive to the rough seas, because the turbulent waves will break the positioning device of the cutter suction dredger, and make the cutter head off the bottom of the water, causing additional losses. Use the three anchor positioning method.

It needs to be equipped with a positioning device during work, which is suitable for the still and slightly wavy river surface, because the positioning device of the cutter suction dredger needs to be inserted into the soil, and the excessive surge will bend the positioning device of the dredger.

Cutter suction dredgers have high productivity and can effectively handle most of the materials.

Material type:

Small and medium-sized cutter suction dredger: Silt, Clay, Sand, Gravel

Large cutter suction dredger: Coral, Broken rock, Small hard stones

Cutter suction dredgers can be used in many environments, such as river dredging, channel dredging, port construction and maintenance, and environmental dredging.

When the depth of most working conditions is relatively shallow, discharge distance is relatively close, the preference is INBOARD PUMP CUTTER SUCTION DREDGER

Inboard pump dredger is the most common type of cutter suction dredger, and it is currently the most cost-effective model. Its pump is installed in the engine room. Because the driving structure of the pump is relatively simple, it can save costs. This design is suitable for most waters and is the most common among small and medium dredgers.

  1. Pump inside the engine room
  2. Normal-size Dredger body
  3. Normal-length Ladder
  4. Normal-size Cutter
  5. Normal mixture density(normal 20%)
  6. One deck crane
  7. Simple drive : main engine drives the pump through the gerbox
