The advantages of the manufactured double girder crane are as follows: Crane box type main girder with computerized optimized design. The end beam is a torsion-resistant welded box beam structure. In the later process of main end beam connection, we adopt the process of laser calibration and sinking hole of the connecting plate, and adopt 10.9 grade high strength bolt connection to ensure stiffness and precision, eliminate stress deformation in the manufacturing process, ensure the accuracy of end beam connection and the parallelism of end beam, and thus ensure the accuracy and smooth operation of the crane.
