Chainladder Dredge

Description

Type of dredge that uses a specifically designed cutting chain to loosen material at the suction as well as convey oversize away from the suction mouth. Depending on the length of the chain section the material can be deposited far enough away so it will not continue to interfere with the digging or suction mouth again.
