ABSTRACT:
A barge tipper comprises a cylindrical floating apparatus 10 defining a chamber 18 into which a barge 28 can be floated. End doors 16 at either end of the apparatus 10 are closed and the barge 28 is clamped in position by hydraulically operated clamps 20. Water is pumped from the chamber 18 to ballast tanks 12 and 14, causing the apparatus to rotate and thus tipping the barge 28. The contents of the barge 28 flow into a first conveyor 22 and are delivered to a second circumferential conveyor 24 which feeds the material to an external conveyor 26.
