A tipping adapter permits a cargo container, which is suspended from a hoisting device, such as a gantry cantilever crane, to be selectively tipped about an axis extending longitudinally through the container so that bulk material, such as coal, grain, etc., may be tipped from the container into a ship's hold or other receiving space. The adapter includes a drive support frame which connects to the crane or a crane-supported container spreader at the connection points normally used in connecting the container to the spreader. A pivotal frame connects to a container in the same manner in which the spreader connects to the container. The drive support and pivotal frames are pivotally engaged so that one or more drive motors, mounted on the drive support frame, can be used to selectively pivot the pivotal frame and thereby tip the container. Controls are placed at the crane control panel to permit selective container engagement and tipping, and interlocks are provided to prevent tipping of the container before it is properly engaged. |
