[0002] In the traditional steel structure construction process, especially the hoisting work of circular steel structure components often faces various challenges. Due to the cylindrical structural characteristics of the components, they are prone to roll during the hoisting process, increasing the hoisting difficulty and risk. In addition, additional fixing and supporting measures are required for circular components during hoisting to prevent displacement or falling during hoisting. These measures usually include using slings, suspension ropes and other forms of fixing devices.
