BUCKET DRIVING CONTROL METHOD OF UNLOADER TO MOVE BUCKET SIDEWISE AND VERTICALLY

摘要

PURPOSE: A vertical lift height and a side moving range of a bucket of an unloader are quantitized by repeating unloading work to improve unloading efficiency. CONSTITUTION: In a method for controlling driving of a bucket of an unloader, a vertical lift height(19) and a side moving range(23) are set by repeating unloading work from a ship. When the bucket is raised to the vertical lift height, the bucket is moved sidewise. When the bucket is raised to an upper end of a hopper(2), lifting is stopped and side movement is further carried out. When the bucket passes one side of the hopper, side movement is decelerated and the bucket is opened.
