Why choose the ECO Cutter Suction Dredger?

Our main benefits

  • High efficiency & production capacity

    The dredge pump is located under the water line to achieve a higher mixture density and higher flow capacity. By placing the dredge pump underwater, the pump vacuum limit will not be limiting to the production of the pump especially at depth more than 6m. The submersible pump is made possible since the dredge pump is mounted on heavy duty bearing assembly and is driven by a hydraulic motor.

  • Maximum production for each project

    The pump speed is variable, allowing it to have the right pressure according to suction depth and discharge pipe line. By varying the speed, the dredge total consumption will be less, and the dredge pump and dredge pipes will wear out less.

  • Self-propelled dredger

    The dredger can be supplied with hydraulic propulsion of an European brand. This will help moving the dredger around without any involvement of tug boat. Two hydraulic thrusters are mounted on the cutter suction dredger that can be controlled from the cabin. This propulsion system is an option system to the standard dredgers.

  • Easy storage & sailing under bridges

    For easy dredge mobilization, transport in the water, transport on the land by flat-bed truck, and for storage, the dredger has two tilting spud systems. Both spuds can be manually tilted and secured to the deck.

  • One-man operation of dredger

    Dredge Yard dredgers can be operated by one man only. The entire dredger and all its equipment can be controlled from the control cabin

  • Transport in containers

    The entire ECO dredger can be transported disassembled using standard containers. Upon arrival at site the ECO dredger can be assembled without the need of special tools. If required Dredge Yard can support with assembly and commissioning by sending service engineers to the site. The dredger can be transported by road on a truck trailer in assembled state. The ECO dredger can be launched into the water using one single crane.

  • REPLACEABLE CUTTER TEETH

    Dredge Yard high efficiency cutter has the possibility to replace the teeth to improve cutting performances. Teeth replacement of cutter head can be done when the original teeth are worn out or to match the teeth with the right type of soil, silt, sand and minerals. The teeth are fixed by means of a bolt and nut connection and can be replace easily and fast. The teeth are available in three different types being sharp point, medium edge and wide edge.

  • CABIN WITH ALL NECESSARIES

    Depending on the location, Dredge Yard cutter suction dredgers are provided with heater or air conditioning system. The cabin is also supplied with noise reduction all around, ventilation on the top, screen wipers, chair that can be adjusted, two mirrors to have a good overview on all operation, and all necessary lighting inside and outside the cabin. To reduce vibration the cabin is clamped on vibration damping system.

  • RELIABLE BRANDS

    The ECO Dredgers are provided with the highest quality components from well-known first-class brands. All manufactured parts like the hull and steel components of the cutter suction dredger are designed, manufactured, and inspected by Dredge Yard team.

  • SHALLOW DRAFT

    The ECO cutter suction dredger is designed with three main pontoons that together provide sufficient floating capacity achieving draft of less than 0.8m (2.65ft). This allows the ECO Dredger to operate in shallow waters.

  • VERSATILITY

    Dredge Yard ECO range of dredgers can be modified between cutter suction dredgers, auger suction dredger, plain suction dredger and swing suction dredger. Dredge Yard can provide the modification parts that can be installed at location during initial dredge purchase or later after the dredger have been used. This makes the ECO dredger a very versatile tool which can be used for dredging all types of soils like sand and gravel, silt, mud and clay. These dredgers can be used in dredge mining, lake dredging, dredging of river and canals, marina dredging, dredging for sand & gravel, clean-up and environmental dredging.

ECO Cutter Suction Dredger types

A suitable solution for each project

ECO200 Cutter Suction Dredger

Depending on the dredging job, the cutter head of the ECO200 Cutter Suction Dredger can be supplied with several types of high quality dredge cutter teeth.

ECO250 Cutter Suction Dredger

ECO250 Cutter Suction Dredger

The ECO250 Cutter Suction Dredger’s pontoon shape and propulsion system provide added maneuverability, making it versatile and efficient.

ECO300 Cutter Suction Dredger

ECO300 Cutter Suction Dredger

An ECO300 Cutter Suction Dredger has a shallow draft, making it suitable to operate in shallow waters and high debris environments.

Main features

All ECO Cutter Suction dredgers come with

Cutter suction head

The cutter head has double curved blades to support the suction system. It is driven by a high torque hydraulic motor mounted on a long shaft that is  supported by heavy duty roller bearing. Under the cutter head drive is the suction mouth, that is aligned with the cutter shape. The cutter teeth are interchangeable for easy maintenance and different conditions or performance. The teeth can be provided with sharp points, medium edge and wide edge.

ECO250 Cutter Suction Dredger

Dredge pump

The submersible dredge pump is driven by hydraulic motor and mounted on a heavy duty bearing block with 3 bearings.

Tiltable spuds

Two spuds are placed at the back of the cutter suction dredger for fixation of the dredger during operation. Both spuds can be hoisted by hydraulic cylinders. Both spuds are tilting manually for easy maneuvering under bridges and for sailing when using the propulsion.

Dredge system

Stiffened cutter ladder suitable for extension of cutter head dredger to different depth. The auger ladder is hoisted by hydraulic operated winch mounted on the pontoon in front of the cabin. A wear resistant, thick and reinforced rubber hose is assembled between the ladder and the pontoon. Two hydraulic operated winches are mounted on the center pontoon for the swing of the dredger. These hydraulic swing winches are connected to the anchors via a heavy-duty tumbler that is mounted on front of the cutter ladder.

Power

Reliable and efficient diesel driven hydraulic power unit. Diesel engine and hydraulic system are cooled by air radiator.
