[0002] Prestressing is a very important part of precast beams. Precast beam tensioning refers to applying prestressing stress to the steel strands in the tension beam body to improve the bending resistance and rigidity of the component, delay the time for cracks to appear, and increase the durability of the component; but before tensioning, the finished steel strands need to be processed and bundled into the beam body. At present, most beam yards still use manual processing, cutting, bundling, and bundling of steel strands. The construction efficiency is low, and the unloading and weaving process of steel strands is slow. The quality of the finished product is unstable and cannot achieve the expected effect. Although automatic unloading and weaving equipment has been developed on the market, it can only be operated in a single position and cannot be moved. The steel strands are stored in storage tanks and need to be cut and transported manually in advance. The degree of mechanization is low and the efficiency is not high.
