Main features

Exchangeable cutter teeth

Cutter teeth can be easily interchanged between three different types depending on the material to be dredged, or replaced when worn out. This can be done quickly and easily due to the bolt connection design.

Hydraulic Propulsion

Auger 200 Propellers

Two hydraulic thrusters are mounted on the back of the pontoons of a CSD ECO 300 dredger. This allows for easy maneuverability around the dredging area, avoiding the need for supporting boats & additional costs.

Tiltable spuds

Cutter Suction Dredger 250 Tiltable Spuds

This dredger is designed with two spuds that can be manually tilted and secured to the deck. This results in easy dredge storage & mobilisation, as well as convenient transport in water and by road on a flat-bed truck.

Extendable depth

Cutter Suction Dredger design

Maximum dredging depth of cutter suction dredger ECO 300 is 6m. However, it can be extended to 12m through an additional adapter placed in between the dredge pump and the cutter head system.

Submersible dredge pump

Cutter Suction Dredger 300 submersible pump

The dredger is equipped with a hydraulically driven submersible dredge pump. It achieves a higher pumping flow of higher density mixture & higher production rates compared to a pump on the pontoons.

Shallow draft

Cutter Suction Dredger Shallow Draught

CSD 300 is made up of three pontoons- one in the center and one on each side. The pontoons provide a floating capacity, which achieves a draft of 0.78m. This allows the dredger to operate in shallow waters.

Reservoir, lake & dam dredging

Reservoir, lake & dam dredging landscape

Dams & reservoirs often accumulate silt & debris, which limit water resources. Cutter Suction ECO 300 is an efficient tool for removal of a variety of materials due to interchangeable teeth. Additionally, it is one-truck transportable, easy to mobilize & launch even on remote sites.

Mine tailing removal & dredging

Tailings ponds consist of mine tailings – byproducts of raw material mining operations. Tailings can contain chemicals or valuable materials, which must be disposed of or further processd. CSD ECO 300 is a compact, powerful dredger, efficient & adaptable for this purpose.

River, canal & channel dredging
