• Maximum production

    ECO Auger Dredgers have adjustable visors
    on both upper side and lower side of the auger head
    that maximize production of silt, sediments, sand and minerals.

ECO Auger Dredgers

Auger Dredgers - Dredge Yard

The Auger head is designed in such a way that the mixture is pushed efficiently to the center of the auger head. This is due to the conical shape of the auger head. That allows more soil, silt, sediments and sand to be collected.

Why choose the ECO Auger Dredgers?

Our main benefits

  • High production capacity at several depths

    The heavy-duty dredge pump is located on the auger ladder under water. This will allow the pump to have a higher pumping flow and a mixture of a higher density resulting in more production than a dredge pump mounted in the pontoons. The vacuum limit will not be reached with a underwater dredge pump especially when dredging at a depth of 6 meters or more.

  • Optimized Production for each discharge length

    Due to the hydraulic drive of the dredge pump, the auger suction dredger can pump mixture of silt, sand and sediments to different discharge pipe length. The speed of the pump can be adjusted to get the right flow and pressure.

  • Low Consumption

    Because the pump speed is variable the pump can be used at the right speed according to the discharge pipe length. The underwater pump also gives a higher mixture density. These qualities make the system more efficient and result in a low fuel consumption per cubic meter production.

  • High Production

    The Auger head design is designed in such a way that the mixture is pushed efficiently to the center of the auger head. Due to the conical shape of the auger head from big diameter at the corners to smaller diameters in the middle the auger head allows more soil, silt, sediments and sand to be collected at the center where the suction mouth is placed.

  • Easy mobilization in the water

    The auger dredger can be supplied high efficiency hydraulic propulsion of an European brand. This dredge propulsion will allow the dredger to moving around the dredging area without any involvement of supporting boats.

  • Replaceable Auger head knifes

    In some cases, the auger head need to work in some compacted material that need to be loosened before it can be sucked by the dredge pump. In this case it is necessary to place cutting knifes on the auger head. Those knifes are fixed to the auger head by means of a bolt connection and they can be easy replaced when worn out.

  • Cabin with all necessaries

    Dredge Yard auger dredge cabin is provided with Air conditioning or heater, depends on geographical location of operating. Also, the cabin is supplied with noise reduction, ventilation, rain/screen wiper, adjustable chair, mirrors, lock door. To minimize the vibration, the cabin is mounted on vibration isolation pads or a vibration reduction mount.

    . The cabin is placed in the middle of the auger dredger and above the center pontoon to allow a for a good overview of all operation.

  • Reliable Brands

    A Dredge Yard auger dredger is provided only with the highest quality components from well-known first-class brands. Manufactured parts like the hull and steel components of the auger suction dredger are designed, manufactured, and inspected by Dredge Yard team. All equipment is from reputable manufacturers with proven designs. The steel components are manufactured under the supervision of Dredge Yard and all dredge components have undergone a detailed inspection.

The ECO 300 Auger Dredger can be easily transported. In assembled condition, the dredger can be transported by road on flatbed trailer.

Main features

All ECO Auger dredgers come with

Auger head

The auger head is designed with a conical shape for better performance. It is provided with cutting knifes for projects that need to cut layers of sediments, sand or minerals. Adjustable visors on both upper side and lower side of the auger head maximize production of silt, sediments, sand and minerals. The auger head drive is a high performance low speed hydraulic motor placed inside the auger head drum and supported by robust bearing assembly.

Sediment Dredger auger head - Dredge Yard

Dredge pump

The high efficiency underwater dredge pump is mounted on a rigid ladder with bearing and shaft.

Power

Our ECO Auger Dredgers are supplied with a reliable and efficient diesel driven hydraulic power unit. The diesel engine and hydraulic system are cooled by an air radiator.

Dredge system

The auger ladder is stiffened to make it suitable for extension of auger 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. For the movement of the dredger back and forth two hydraulic winches are provided with roller assembly.

Pontoons

The base of  our ECO Auger Dredgers consists of one center pontoon and two side pontoons, that are stiffened with longitudinal and cross bars. For hoisting the auger head, dredge pump and auger ladder a gantry with sheave assembly is placed between the two pontoons. The operating cabin is mounted on center pontoon and supplied with cooling by air-conditioning or heater.

Applications

Our ECO Auger dredgers are perfect for

Dredge Yard environmental dredging

ENVIRONMENTAL DREDGING

Environmental dredging is to dredge with minimum impact on the environment. The ECO Dredger with auger excavating tools avoids dispersion of pollutants.

Dredge Yard water intake cleaning & dredging

WATER INTAKE CLEANING & DREDGING

Proper and regular maintenance is needed to keep basins clean and the capacity at it’s maximum. Therefore we offer water intake cleaning & dredging.

Dredge Yard channel dredging

RIVER, CANAL & CHANNEL DREDGING

River, canal & channel dredging is important to keep the waterways open for inland transport & navigation and is vital for flood prevention projects.

Options for the ECO Auger Dredgers

To customize your auger head dredger

Hydraulic propulsion

For the easy movement of the auger suction dredger a compact and efficient hydraulic Thrusters can be mounted at the back of the side pontoons. Steering is done from the operating cabin by a joystick.

Extension of dredging depth

The standard dredging depth can be extended to meet the requirement of a certain project by adding an additional adapter between the dredge pump and the auger head system.

Cutter Suction Dredger

The dredger can be modified to cutter suction dredger by replacing the ladder front piece from auger head to cutter head, changing the orientation of the winches, placing spuds and spud hydraulic cylinders. All those changes can be supplied by Dredger Yard and they are all plug and play system.

Plain Suction Dredger

The dredger can be modified to plain suction dredger by replacing the auger head, changing the orientation of the hydraulic winches. The plain suction head can be supplier by Dredge Yard and it fits to the existing foundation and flanges.

Automation & control

Automation control system can improve the overall performance of the dredger and makes the dredging process more visible. Several types of dredging automation and controls can be provided depending on the level automation and project requirements.

Extra’s

to further expand your equipment

Spray Nozzle

For discharge spray on longer distance a special designed spray nozzle can be provided for soil, silt, mineral or sands. This nozzle can be made from wear resistant material depends on the dredging mixture.

Spare parts

Spare part package and maintenance guidance can be supplied for several years. The spare parts can be supplier at initial purchase of the ECO Auger Dredger or after operation. Dredge Yard will strive to keep necessary stock of spare part to serve customers when needed.

Discharge pipe line

An HDPE discharge pipe line can be provided with several types of floaters and rubber hoses.

Training

Dredge Yard team can provide crew training at location or at Dredge Yard facilities as well as supervise assembly, disassembly, commissioning and mobilization of the auger dredger.

Transport

your ECO Auger Dredger anywhere
