[0035] It should be noted that when loading construction machinery, the first motor 609 is started to drive the chain 612 through the first reduction box 610 and the driving sprocket 611, so that the chain 612 drives the first rotating shaft 603 to rotate through the driven sprocket 613, thereby driving the driving pulley 604 to rotate, and then with the cooperation of the driven pulley 607, the belt 608 rotates to pull the construction machinery to the top of the device.
