COIL UNLOADING METHOD FROM SHIP AND DEVICE THEREOF

PROBLEM TO BE SOLVED: To correctly unload in order coils stored in the hold of a ship by an unloading crane provided on a quay. SOLUTION: When a ship 3 storing coils 5 is moored at a quay 6, the three dimensional coordinated position of a hoisting accessory 17 of an unloading crane 13 is detected by first detecting means 19, 20, 22, and the dislocated quantity from the prescribed position of the moored ship is detected by second detecting means 10, 11. By correction based on the deviated quantity between the three dimensional coordinated position of the coils 5 in a hold 4 stored in a memory and the prescribed position of the moored ship, based on the detected coordinated position of the hoisting accessory 17 and the corrected coordinated position, the moving direction and the moving quantity of the hoisting accessory 17 are obtained by computation and displayed by a display means. The operator of the crane 13 sees the display content of the display means, and operates the hoisting accessory 17 of the crane 13.
