The crane end carriage welding adopts robot welding, and the welding seam is full and round. The finished end beam is positioned and processed once on the CNC machine tool to ensure dimensional accuracy and fit tolerances. The crane end carriage of the crane includes a U-shaped box beam, a driving device, a transmission device, a braking device, and a wheel set to form an end beam. The end frame bears the longitudinal movement of the main beam. Its advantages can reduce the rail gnawing wear caused by wheel skew, and it is not easy to cause wheel climbing and derailment failures.
