At the same time, according to the requirements of the fall radius specification for high-altitude operations, a warning belt is set outside its radius and it is ensured that there are no debris on the ground in the area that hinders the construction. Then the four groups of beams 401 are opened in sequence, so that the beams 401 and the self-propelled vehicle body 3 are set at 90 degrees, and the threaded column 403 is rotated by the handle so that the bottom end of the threaded column 403 fits with the top of the self-propelled vehicle body 3, so that the beam 401 is fixed.

The operator enters the guardrail 6, connects the safety belt 206 with the self-locking anti-fall device 204 and the vertical life rope 202 to form a vertical protection system through the connecting rope 205, and then drives the first crossbar 502 to slide through the hydraulic cylinder 503, so that the first rotating rod 501 and the second rotating rod 504 rotate in the opposite direction at the same time, so that the lifting platform 505 drives the guardrail 6 to rise until the operator reaches the specified height of the operation. After the operator completes the construction, the guardrail 6 is slowly lowered to the minimum height. During the whole process of descending, the vertical life rope 202 is controlled not to be stuck in the scissor structure 5. After the equipment descends and stops, the operator removes the connecting rope 205, the safety belt 206 and the self-locking anti-fall device 204. Then the anti-overturning structure 4 is folded up, and the crossbeam 401 is rotated to a position parallel to the self-propelled vehicle body 3. After the operation is completed, the site is cleaned up and the operating device is properly kept.
