The structure of the ring-lock stair tower is the same as that of the φ60 ring-lock scaffolding, and the cross-section dimension of the stair tower is 1.5×3.0 m. The safety of the stair tower is quick to assemble and disassemble, and the force is reasonable.

Bearing capacity of the stair tower 
As the height of the tower erection increases, the force it bears decreases. When it is set to 150m, it can still withstand the force of 0.25KN/m×150m=37.5KN, so it is safe to work when it is 150m high (the tower must be attached to the wall every 4.5m).
