<p>The loose bulk material unloading installation is esp. for unloading of ships. It comprises a crane gantry, a jib, and a bucket conveyor. The input unit consists of a main carrier, a pivot arm and a control link. A connecting linkage is slidable along the main carrier so that the inclination of the pivot arm w.r.t. the main carrier can be adjusted. The main carrier is rotatably mounted in an end piece coupled to the jib. The jib is horizontally guided along the gantry. The jib, complete with end piece and input unit, can be swung from the working to rest position through a linkage mounted on the horizontal guide of the jib.</p> |
