Abstract

PURPOSE:To aim at the continuous and highly efficient unloading of bulk cargoes in the whole area of a hold, by installing crane arms making free derricking motion and a horizontal support arm via a rotatable boom and frame controlled from a crane car at quay, while attaching a bucket chain between horizontal arm nose and frame top end. CONSTITUTION:With a motor unillustrated herein, a frame 7 is rotated and first and second arms 13 and 15 are turned to a different direction each. In addition, a rod 14a of a driving cylinder 14 is moved back and thereby the first arm 13 is operated into derricking motion. With this, an L-shaped second arm 15 is always kept in level through combined actions by a link 16. Using this, a bucket chain 9 is driven and bulk cargoes are unloaded from the hold by a bucket 8a. In this way, with a combination of the movement of the crane car 2, rotations of a boom 5 and the frame 7 and derricking motion of the first arm 13, the stowed in bulk in the whole area of the hold can be continuously unloaded in a highly efficient way.
