Abstract

PURPOSE:To simplify the operation control of an unloader for stevedoring by carrying out stevedoring work of ore etc. by means of only traveling of an unloader, lateral movement of a self-running truck, vertical movement of a column frame and vertical swing of an arm. CONSTITUTION:Ore or the like is dug and scraped up by forcing a bucket chain 22 wound around sprockets 23 through 26 to make counterclockwise turning run under the condition in which the boom 11 and th girder 12 of an underloader and self-running truck 13 are positioned in respectively assigned spots by their own traveling and lateral movement respectively, a column frame 21 is lowered and as arm 31 is kept horizontal. The ore is delivered out into a chute 27 along a slope behind the sprocket 23 and carried out by means of a delivery conveyor 17. When the draft of a ship 9 rises, the column frame 21 is lifted. Further, both the arm 21 and the sprocket 26 are lifted by operation of a cylinder 32 so as to change the scrape angle depending upon the state of loading. Thus, both simple structure and easy operation control can be achieved.
