1. the process of erecting and dismantling the operation platform is complex. Each longitudinal and transverse steel pipe and the peripheral guardrails need fasteners for connection, and a safe vertical net, a flat net and a frame plate need to be laid. Therefore, a professional scaffold worker is required to operate, and the time is long;
2. when the tower crane is installed or dismantled, the materials are inconvenient to transfer, and a passage from a building to the tower crane needs to be built firstly;
3. after the platform is erected, the existing period is long, the tower crane needs to be disassembled when being dismantled, and the platform cannot be used in a turnover manner;
4. the comprehensive labor cost and the material cost are higher.
