The mast section of the construction hoist is mainly composed of pipes, frames, and racks. The quality of a mast section lies in the strength and the smoothness of operation.
First of all, Q345B straight seam steel pipe has the advantages of high precision, uniform wall thickness, and high brightness inside and outside the pipe. In this way, it can be ensured that in the actual assembly process, the cumulative error between the outer surfaces of each standard section is small. The cage will rise steadily during the crawling process.
Secondly, Q345B straight seam steel pipe has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. It can be used as construction elevators, construction elevators and other structures that bear dynamic loads. It can be used for various structures in cold regions below -40°C. Generally better than ordinary Q235 material pipe.
