This crossing may be referred to as a first crossing because it is above the roll platform 130 and is formed before it passes around the pulley after being pulled from the reel.

Similarly, the second anti-sway group 150 may comprise a third drum 151 and a fourth drum 153, the third anti-sway rope 152 is wound on the third drum 151, the fourth anti-sway rope 154 is wound on the fourth drum 153, and the third drum 151 and the fourth drum 153 are interleaved with each other, the pulley disposed corresponding to the third drum 151 is a third pulley 165, the pulley disposed corresponding to the fourth drum 153 is a fourth pulley 167, then the third anti-sway rope 152 is wound around the third pulley 165, the fourth anti-sway rope 154 is wound around the fourth pulley 167, the third drum 151 is disposed between the fourth drum 153 and the fourth pulley 167, the fourth anti-sway rope 154 drawn from the outlet of the fourth drum 153 does not interfere with the third drum 151, the fourth drum 153 is disposed between the third drum 151 and the third pulley 165, the third anti-sway rope 152 drawn from the outlet of the third drum 151 does not interfere with the fourth drum 153, and the third anti-sway rope 152 and the fourth anti-sway rope 154 form an intersection, that is, the third and fourth

Wherein, each reel is correspondingly provided with a driving mechanism 170, and the driving mechanism 170 is configured to drive the corresponding reel to rotate. It can be understood that actuating mechanism 170, reel and the anti-sway rope of winding on the reel have constituted an anti-sway mechanism, and in this application, four anti-sway mechanism independent control can realize that hoist upper bracket 120's gyration, vert and translation have improved hoisting system's automation and adaptability.
