![]() This makes large dredging equipment transport difficult and expensive. Dredging projects often take place away from ports and in remote locations that are difficult to reach. One of the challenges that clients face, is transporting their dredging equipment to project site. This makes the dredger easy to transport, launch and store. Therefore, the usual breadth of the dredger (3.2m) is reduced to under 2.4m width when folded. As illustrated below, the side pontoons fold upwards. ![]() It can dredge to a depth of 32 meters, and has a bucket with a volume of 40 cubic meters.Auger dredger ECO 200 is the only dredger in the market to feature fold-able pontoon (convertible) design. The full barge transports the dredged material to a designated location.īoskalis has around 18 of these vessels operating on projects all over the world, including the Magnor, the largest backhoe in the world. The dredged material is discharged into the transport barge. The filled bucket is positioned above the barge by rotating the excavator on the turntable. When the bucket is full, an upward movement of the boom and stick lifts the bucket above the water to start swinging. The bucket excavates soil in a combined backward and upward movement of the boom, stick and bucket. A transport barge is moored alongside the backhoe dredger. The backhoe dredger is anchored firmly with three spuds. The backhoe dredgers can dredge a wide range of materials very precisely and they operate mainly in shallow and enclosed waters. Backhoe dredgers (BHDs) are stationary dredgers with a hydraulic excavator installed on a pontoon.
