XCMG Material No. 803300774 Rear Mast Anti-Roll Back Control Valve is a safety control device specially designed for XGC400-I 400-ton crawler crane. It precisely adjusts the thrust of the mast cylinder through hydraulic drive to offset the boom roll back moment in real time and prevent the risk of overturning caused by the instability of the mast. As the core component of the original factory, its structural strength, response speed and adaptability all meet the strict engineering standards of XCMG, ensuring the safe operation of the equipment under heavy-duty lifting and high-risk working conditions.
