Dredges and Dredging Equipment

Hydraulic Dredgers

Hydraulic dredgers use water to transport the dredged material. The material is picked up by the suction of a pump, then transported through a pipeline in the form of a slurry.

Example

Cutter Suction Dredges
Horizontal Auger Dredge
Dustpan Dredge
Plain Suction Dredge
Jet Suction Dredges
Bucket Wheel Dredges

Mechanical Dredgers use a bucket , clamshell or other mechanical means to scoop the material from the bottom. If the material cannot be discharged close to the dredge, then it must be stored for subsequent transport.

Example

Clamshell Dredges
Excavator Dredges
Backhoe Dredges
Bucket Ladder Dredges
Environmental Dredges
Dipper Dredges

Hopper Dredgers

Usually ship-form in design, a hopper dredger deposits the dredged material in an on-board hopper for transportation. Both mechanical and hydraulic designs are common for loading the hopper as well as for discharging the dredged material.

Example

Trailing Suction Hopper Dredge
Clamshell Loading Hopper Dredge
Bucket Ladder Hopper Dredge
