[0033] When in use, the hook rigging 3 is docked with the cargo and lifted to the required area. When encountering bad weather and needing to block rain and snow, the motor 48 in the box cover 43 works, the worm 49 rotates, and the worm wheel 410 drives the transmission rod 411 to rotate on the stand 412, and the belt 47 runs, so that the rotating rod 46 rotates, the connecting belt 44 is released, and the baffle 42 is lowered to be level with the bottom plate 41, thereby increasing the shielding area of the top of the beam 2, and then protecting the crane and the lifted cargo from rain and snow.
[0034] According to some embodiments of the present application, optionally, the motor 48 and the stand 412 are both installed in the box cover 43. This has the effect of isolating the motor 48 and other accessories from the outside world.
[0035] According to some embodiments of the present application, the hook rigging 3 is optionally located below the baffle 42, which can protect the cargo on the hook rigging 3 from rain and snow.
[0036] According to some embodiments of the present application, optionally, both sides of the baffle 42 are connected with vertical plates 413, which can shield rain and snow from multiple directions.
