the position signal of the shuttle 10 is acquired through the first detection component 710, and the shuttle 10 is stopped when the shuttle 10 reaches a predetermined position. The height of the fork 220 is adjusted by the elevation driving mechanism 400 so that the height of the fork 220 is aligned with the height of the first transfer line 30. The forks 220 extend out of the bottom of the articles inserted on the first conveyor line 30. The lift drive mechanism 400 is again activated and lifts the item via the forks 220. The forks 220 are then retracted back and the article is then forked by the forks 220 onto the cargo frame 210.

Then, the shuttle 10 is started again until it is stopped when another preset position is reached. The fork 220 is extended to place the article on the second conveyor line 40 and the height of the article is lowered by the lift drive mechanism 400 until the article falls on the second conveyor line 40. The forks 220 are retracted and reset to complete the transfer of the article.
