Bumper for Zoomlion QY50V Truck Crane
This front bumper assembly is specifically designed for the Zoomlion QY50V truck crane – a 50-ton class mobile crane widely used in construction, bridge building, and heavy lifting operations.
Manufactured from high-strength , this bumper restores the original crash resistance and chassis protection of your crane. Unlike universal aftermarket parts, this unit matches the exact mounting hole positions, contour, and bolt spacing of the QY50V frame, which reduces installation time by more than 40% and eliminates the need for drilling or welding.
