In addition, the scarcity of human resources and the continuous increase in labor costs have posed more severe challenges to the upgrading of port equipment and the improvement of production efficiency. The lifting, flipping and welding of traditional telescopic beam structures are increasingly unsuitable for current production needs due to their extremely low production efficiency, high safety risks, and rough component positioning.
