[0002] The pipe pile loading crane beam is a special lifting device used for ships. It is mainly used to lift various types of ship components while accurately positioning, assembling and adjusting them on board. The crane beam usually adopts a solid high-strength steel structure, has a large load-bearing capacity, and has good rigidity and durability. The existing crane beams are usually straight as a whole, which is not convenient for transportation and storage. Overload is prone to occur during the lifting process, and the overall force is uneven, which affects the load-bearing capacity and produces large shaking. This may cause imbalance and instability of the entire lifting system, posing a great safety hazard. In addition, the crane beam has a low structural strength, may bend and deform after long-term use, and has poor durability. Utility Model Content
