Abstract
A container dumping mechanism includes first and second sides. A carrier is positioned on the frame for movement relative thereto. The carrier includes a mechanism for supporting a container to be dumped. A dumping assembly is operably connected to the carrier and includes an actuating mechanism which is selectively actuable in first and second modes. In the first mode, the actuating mechanism is actuable to raise and generally invert the carrier at the first side of the frame to dump the contents of the container over the first side. In the second mode, the actuating mechanism is actuable to raise and generally invert the carrier at the second side of the frame to dump the contents of the container over the second side. The actuating mechanism is further actuable in a third mode for rotating the carrier essentially in place about a longitudinal axis to dump the contents of the container directly therebeneath. The actuating mechanism comprises an extensible/retractible boom comprising telescoped inner and outer portions. A cable take-up mechanism is connected to the cable for shortening the effective length thereof to extend the outer boom portion and cause the carrier to rotate.
