Main Features

One container transportable

auger dredger foldable for transport

This compact budget dredger can be transported on one truck in an assembled state and foldable pontoons. The compact design makes it easy to transport, launch, operate & store for later use.

Caterpillar Engine

The dredger includes a world-renowned Caterpillar engine, which is a lightweight engine with low CO2 emissions. Its compact size allows for small, but powerful Auger ECO 250 design.

Convertible design

auger dredger folded for transport

Side pontoons of ECO 200 can fold upwards. Thus, it is easy to mobilize, launch on project site & store for later use. It is very practical for reoccurring maintenance projects.

Exchangeable knives

When needed, cutting knives are fixed to the auger head through a bolt connection. They can be easily interchanged between different types of knives or replaced when worn out.

Submersible dredge pump

Cutter Suction Dredger 300 submersible pump

Hydraulically driven submersible dredge pump achieves higher pumping flow of higher density mixture. Therefore, its overall production rates are higher than of a pump mounted in the pontoons.

Optional: Propulsion

auger dredger propulsion

Auger dredger ECO 250 can be supplied with 2 hydraulic thrusters in the back of the pontoons. This makes the dredger self-propelled, resulting in easier maneuverability around the dredging area.

Auger ECO 250 Applications

Environmental dredging

Dredge Yard environmental dredging landscape

Adaptive auger head featured on Auger ECO 200 causes minimal to no turbidity, protects marine animals from entering the suction system & avoids dispersion of pollutants. Due to its environmentally friendly design and precision, it is especially suitable for cleaning contaminated soils.

Canal and channel dredging

channel dredging landscape

Canals & channels require regular maintenance dredging to retain safe depths for navigation. Adaptive auger head ensures high production rates of fine, loose sediments & low turbidity to protect the environment. This dredger is compact & can be easily removed and stored for later use.

Water intake cleaning and dredging

water intake cleaning & dredging landscape

Auger ECO 200 is a good tool for water intake cleaning at industrial plants. It causes minimal to no turbidity to maintain high quality of water entering the plant. Additionally, it removes loose sediments in a precise manner without damaging infrastructure of the water intake channel.
