OPERATING METHOD FOR UNLOADER

摘要

PROBLEM TO BE SOLVED: To prevent a bucket from interfering with a ship by modifying a cargo trajectory of the bucket based on the height position of the ship. SOLUTION: A height detector 21 disposed in a boom 4 of an unloader 8 detects a height position of the ship 13, determines a cargo trajectory of the bucket 10 from the inside of a hold to a position over a hopper 15 during cargo working in response to the detected value, and moves the bucket 10 by an automatic operation according to the determined cargo trajectory.
