Therefore, the embedded part with the traditional simple structure is not suitable for being used on the tower hanging frame with a large layer height, and the use safety is very low. In the actual construction process, under the condition of excessively strong wind force, the cantilever of the tower crane swings to drive the tower crane main frame to swing, so that the embedded part pulled by the tower crane main frame with high height and heavy weight is pulled off, and the method is very dangerous.
