The  crane QY50KD_1 is the most powerful model in the industry with the highest boom length of its class. It has a main boom of 45.5m and a counterweight of 9.5t. The design focuses on strengthening the performance of the medium and long boom lifting conditions, and the lifting performance is relatively old. The 50-ton model has increased by more than 14%, which is more than 5% higher than the industry.

The hydraulic system chooses a high-distribution hydraulic system with a fixed displacement pump and a variable motor. Through the reasonable layout and matching of the system, it perfectly adapts to the requirements of smooth operation. Only when the operation is stable can the operation safety be guaranteed; the lifting mechanism uses a high safety factor φ18 large-diameter steel wire rope , The maximum single rope pulling force is 50KN, which supports powerful lifting performance.

QY50KD_1 uses sinking H-type double-section outriggers, has the industry's largest 7.5m outrigger lateral span, and strengthens the key stress points of the chassis to show strong resistance to deformation under heavy loads and avoid hoisting When the "down to eight" is vacillating, it helps you work safely.

The highest configuration for power use: 336 horsepower Weichai National VI engine, with 9-speed gearbox, double reduction bridge, suitable for high-load tires, maximum climbing capacity 45%; also upgraded 350L super aluminum alloy fuel tank, battery life increased by 10% .
