Dredger D 110/47-I-1

Dredger D-110/47- I-1 

Dredger D-110/47-I-1 with electrical motor of the main pump is designed for the commercial extraction of sand and sand-gravel mixture in the exploitation of soils of I-IV category at the  depths up to 9.5 meters. Also it is use to clean beds of rivers, canals and ponds of mud, sand and other sediments.
This dredger can be applied as a pumping station to transfer water and pulp containing up to 20% of non-metallic materials in case of its discharge to a grizzly or deposit site, as well as to a loading platform, equipped with different types of dehumidifiers.
