Truck crane QY50K5C_1 adopts self-made four-axle G-type chassis, new two-chamber model of the year; Weichai 336 horsepower National VI engine, Shaanxi gear transmission 9 gears; 6.3*7.9m two-stage H outrigger with fifth outrigger; five 46-meter main boom, 2 16-meter jib, dual independent hoists, pilot hydraulic control system
The full outrigger is 46m, the width is 18m, the hoisting weight is 7.3t, and the lifting capacity is 6%~11% higher than the industry on average.
With 15 working conditions of the main boom, select the appropriate outrigger combination to achieve the maximum lifting capacity and meet various hoisting operations. It also has a half-extended outrigger condition.
QY50K5C_1 continues the optimized design of XCMG crane structural parts. Whether the crane is stable or not depends on the four major structural parts:
Boom: using high-strength grade cylinder plate, high safety margin;
Compression type boom tail structure, under the condition of the same boom length in the industry, the full extension overlap ratio is the highest.
The main boom telescopic system adopts the special telescopic balance valve core of XCMG. The internal leakage of the telescopic balance valve is small, and the sealing performance is improved by more than 60%.
Frame: XCMG's exclusive whole machine structure optimization technology increases the number of partitions, increases the thickness of the plate, and further improves the safety factor.
Turntable: single-layer vertical plate and local box structure, with large longitudinal rigidity and strong bearing capacity;
The main material is high-strength steel, with good fatigue resistance;
Outriggers: The optimal aspect ratio design of the outriggers is box-shaped, with strong bearing capacity;
The sunken H-shaped outrigger has high working stability;
Not only the structure is powerful, but also standard 315/80R22.5_22PR high-level tires, the maximum load capacity of the whole vehicle is 51t, and the whole vehicle is equipped with 47.8t to drive easily. It can also be equipped with auxiliary tools such as skids and slings, and there is no risk of tire blowout for a long time.
