firstly, a travelling crane runs above the main beam 1, then a travelling crane sling and a lifting hook are put in, and the travelling crane lifting hook is placed between the first radial plate 62 and the second radial plate 63 by means of a manipulator on site. The axle pin, which is fitted into the axle-barrel ear hole of the first web 62, is lifted up using a robot arm and moved into the axle-barrel ear hole of the second web 63. The bolt 61 is pushed to pass through a crane hook hole to a hoisting station, a shaft pin arranged in a shaft barrel lug hole of the second spoke plate 63 is lifted out and moved into a pin hole at the end of the bolt 61 to fix the bolt 61. 4 first camera units 71 and second camera units 72 at two ends of the main beam 1 are started, and it is confirmed that each camera unit works normally.

Then, the crane hook moves upwards to ensure that the height of the lower end of the hanging box 3 from the ground is not more than 0.1 m. According to the distance between the lifting points of the part to be lifted, the lifting distances of the sub-beam 2 and the lifting box 3 are sequentially adjusted by means of a manipulator, namely, the handle 5 of the sub-beam 2/the lifting box 3 is lifted, the sub-beam is translated to a preset lifting distance position, the handle 5 is placed down by aligning with the lug, and the lug is clamped into the corresponding groove. After the hanging distance is adjusted, whether the levelness and the orientation of the main beam 1 are accurate or not is confirmed by comparing the output videos of the shooting units, and if the levelness and the orientation of the main beam are accurate, reasons need to be searched and corresponding adjustment is carried out.

The crane hook is then moved upwards again so that the lower end of the pod 3 is at a height slightly greater than the length of the hook 4 to be installed from the ground. The hooks 4 matching the component suspension points are selected and then installed and the hooks 4 are assembled as described above. After all installing four lifting hooks 4, through comparing camera unit output video, confirm whether the levelness of girder 1, orientation are accurate, if have a problem, need look for the reason and carry out corresponding adjustment.

After the operation is finished, the travelling crane, the lifting hook and the lifting appliance below the travelling crane slowly move to the position above the part to be lifted for parking, videos are output through comparison of the camera shooting units, whether the levelness, the direction and the parking position of the main beam 1 are accurate or not is confirmed, and if the problems exist, reasons need to be searched and corresponding adjustment and correction are carried out.

And finally, after the situation that the lifting hook is not correct is confirmed, the crane is remotely controlled to slowly lower the lifting appliance, and the lifting hook is aligned with the corresponding lifting hole in the component. Four lifting hooks 4 all fall into behind the lewis hole of work piece 8, continue to transfer the hoist, when the contact of end under the lifting hook and lewis hole bottom (observe the height of hoist or whether have the upper end of lifting hook to shift up through the observation window through horizontal camera unit observation hoist), stop promptly transferring the hoist. The four hooks 4 are rotated by 90 degrees in sequence by using a manipulator, so that the upper ends of the hooks fall into a lifting station. The crane hook is slowly lifted to finally and stably lift the component away from the storage position.

After the part is hoisted to a preset position, the unhooking of the lifting hook of the lifting appliance and the hoisting point of the part, the unhooking of the lifting hook of the crane and the lifting appliance and the like are carried out in the reverse order of the assembly sequence of the lifting appliance.
