5. A large diameter preformed tubular member hoisting apparatus according to claim 4, characterised in that, The length of the whole circular tube is the same as the length of the base plate, and the length of the half circular tube is less than 1 / 2 of the length of the whole circular tube.

6. A large diameter preformed tubular member hoisting apparatus according to claim 4, characterised in that, The rotating shaft comprises a shaft and a baffle at both ends of the shaft.

7. A large diameter preformed tubular member hoisting apparatus according to claim 4, characterised in that, The baffle at both ends of the rotating shaft on both sides of the supporting plate comprises a first baffle, a second baffle and a third baffle spaced and sleeved on the shaft from inside to outside.

8. A method of hoisting a large diameter pre-fabricated tubular member, characterised in that, The baffle at both ends of the rotating shaft between the rotating shafts on both sides of the supporting plate comprises a first baffle and a second baffle spaced and sleeved on the shaft from inside to outside. The first baffle is attached to the port of the corresponding circular tube. The shaft between the first baffle and the second baffle is a rope connecting part.
