In this way, by adjusting the connection belts 1 to pass through different lateral adjustment holes 11, the distance between the two connection belts 1 can be changed, and thus the lifting of the waverider structural members of different sizes can be adapted.
It is worth noting that, in the lifting appliance, the number of the lifting rings 7 is one, the number of the lifting belts 8 is two, and the two lifting belts 8 and the cross beam 9 form a triangle, so that in the lifting process of the wave-rider structural member, the cross beam 9 is easy to rotate in the plane where the cross beam 9 is located relative to the lifting rings 7, thereby causing the rotation of the wave-rider structural member and influencing the lifting stability of the wave-rider structural member, therefore, the lifting appliance further comprises an anti-rotation cylinder which is sleeved outside the lifting rings 7 and is in sliding connection with the lifting rings 7, a clamping groove is formed in the anti-rotation cylinder towards one end of the lifting belt 8, and the lifting belts 8 are inserted into the clamping groove. Like this, suspender 8, crossbeam 9 and prevent that a commentaries on classics section of thick bamboo towards suspender 8's one end can constitute trapezium structure, compare in triangle-shaped structure, the more difficult rotation of trapezium structure to can reduce and take place the pivoted condition and take place at the lifting by crane in-process by the wave body structure. It should be noted that, when the hanging strip 8 is installed or needs to be replaced, the rotation preventing cylinder can slide towards the direction away from the hanging strip 8, so that the joint of the hanging ring 7 and the hanging strip 8 is exposed, and the hanging strip 8 and the hanging ring 7 can be conveniently detached and connected.
