The dump bin system (10) includes a dump bin (100) which is located on a support frame (300) supported by a gantry 5 (400). In use, the dump bin (100) is filled with earth at the floor of the excavation site and transported by crane to its position supported on the support frame (300). The dump bin (100) has a drop bottom to discharge earth into a trailer (not shown) positioned below the support frame (300). The dump bin system (10) includes a safety control system (200) which 10 prevents opening of the drop bottom whilst the dump bin (100) is in transit between the floor of the excavation site and the support frame (300).</p> |
