  • Suction head for sediment dredge
    Patent number: 7552551

The movable member(s) enables a user to clear the dredge head of plugging masses or blockages without having to de-energize the dredge system pump. Also, the movable member(s) enable a user to clear the dredge head of plugging masses or blockages without requiring the user to manually, by using his or her hand, withdraw the plugging masses or blockages from the opening of the suction/dredge heads.
