It is suitable for high-altitude rapid installation scenarios such as the shaft construction of TV towers.

[0017] The bolts of the fixing components support ground pre-adjustment. By rotating the screw to adjust the stroke by ±150mm, the verticality of the auxiliary frame components can be finely adjusted. This eliminates the need for construction personnel to repeatedly climb to high places for alignment, reducing the time spent working at heights by 60% and significantly reducing the risk of falls.
