Ship cargo loading/unloading method and cargo transfer apparatus for use in carrying out the same

摘要

A cargo transfer apparatus 31 having a hand--over stage 42 for temporarily carrying pieces of cargo is situated on a wharf 4, such that the hand-over stage 42 is positioned in a region containing the space inside a hold of a ship 1 moored at the wharf 4 and a space above the hold. Pieces of cargo are transferred between the hand-over stage 42 and a cargo loading/unloading apparatus such as a shore crane 52. The hand-over stage 42 functions as an intermediate buffer which accommodates any difference between the state of loading of the cargo into the ship and the state of convey of the cargo to the hand-over stage, thus shortening the cycle time of the cargo loading/unloading apparatus and reducing the waiting time of the cargo handling components of the whole loading/unloading system, contributing to reduction in the cargo handling cost, improvement in safety and ease of cargo handling.
