Product Description
1. Cutter suction dredger introduction
This is a kind of non-self propelled, hydraulic cutter suction dredger, with dismantle type of pontoons and can be assembly at the work place. Equipment on the dredger are as bellows: traversing device, cutter ladder lifting device, trolley device, hydraulic device for spuds lifting and down, and deck crane. The working process is as following: the cutter head cut the sand and mud underwater for mixture of slurry, then through the dredging pump, then by pipeline to send slurry to the work place.
