Our Cutter Suction Dredges can dredge in waters from 0, 40 metres down till 40, 00 metres.Įco Dredging Ltd has at her disposal more than 20 cutter suction dredges with size varying from 5” to 12” dredge pumps. The small dredge can also operate as any other cutter suction dredge and work on wires and anchors. The extended ladders can reach lengths of 20 metres. The long ladder also allows for dredging under pontoons, yachts, fishing boats and anything else afloat. With extended and articulated ladders a wide area can be dredged. When the dredger is positioned on the spuds the ladder with the cutter head moves from starboard to portside and back by means of hydraulic rams. It is positioned on wires and anchors and/or spuds. The Cutter suction Dredge is a stationary dredge. Our cabins on all equipment can be pressurized as to work in strongly contaminated sediments. This is a very fast method and can be done when the sediments in the waterway are not or only slighted contaminated.Įco Dredging Ltd has many years of experience in the dredging of lightly The pump sucks up the pushed up sediments and pump/sprays it over the land right behind the excavator. The pump is placed in the specially designed bucket at the end of the jib. The machine is a strong excavator on tracks with jib and pump. In these cases the contaminated sediments are excavated with the aid of excavators or pushed up by the floating bulldozers.ĭredged sediments can also be transported over greater distances inĪ special machine is the combination of mechanic and hydraulic dredging. Citizens are worried by the hazardous contents pumped in and do strongly oppose the presence of such a deposit in their neighborhood. The costs of the construction and organization of such a deposit are very high. In case sediments on the water bottoms are very contaminated it is mostly impossible to pump the dredged sediments to a disposal site. Hydraulic excavators (with long jibs if required) on land, on pontoons or on their own stabilizing legs, small hopper barges and push boats, floating bulldozers are very unique machines that have proven their effectiveness
and transported over water in hopper barges and over road in trucks with water tight containers. Mechanical dredging (as opposed to hydraulic dredging with cutter suction dredges) is the dredge method in which sediments are dredged with machines like excavators, floating bulldozers, etc. Eco Dredging Ltd has a wide range of mechanical dredge equipment at her disposal.
