Mini suction cutter dredger, excavator

The dredger cleans water bodies from silt, vegetation, sludge, tailings, garbage. Performs dredging and bank consolidation works. The dredger can also take part in the construction and operation of hydraulic structures. Extracts sapropel, peat, mud, etc. The multi-purpose system can cope with any landscaping task. A special feature of this dredger is the unique milling cutter complete with a grinder, which contributes to the smooth and clog-free operation of the pump. Spuds enable the system to perform its works more accurately. The pontoon is divided into two sealed compartments and equipped with automatic bilge pumps.
