CONSTITUTION:To unload a plurality of ingot pieces 1 scooped by individual claws 11, 12, 13, 14 to a freight car 3, individual claws 11, 12, 13, 14 are lowered from above the freight car 3 so that individual stoppers 19, 20, 21 pass through the horizontal spaces between individual claws 11, 12, 13, 14. Accordingly, individual ingot pieces 1 supported on individual claws 11, 12, 13, 14 are settled within a horizontal space size L between individual stoppers 19, 20, 21 and individual screens 22, 23, 24, 25, 26, 27. Under this condition, individual claws 11, 12, 13, 14 are horizontally moved to the right by means of the travelling force of the claw crane, then the right end ingot piece 1 is stopped by individual stoppers 19, 20, 21 and the ingot pieces 1 fall on the freight car 3 in sequence from the left side. |
