Truck crane QY20K5C has a five-section "U-shaped" 40-meter main boom with a maximum lifting height of 47.6 meters. This is the previous 25-ton lifting capacity level, which can meet more than 80% of the hoisting needs of loose work in the market, especially in its high frequency The performance is more remarkable in the field of working condition hoisting.

The pilot control operating system makes its maneuverability consistent with 25 tons, ensuring the convenience and comfort of the driver. The minimum stable speed of rotation reaches 0.1°/s, and the minimum stable speed of hoisting (at the reel) is 2.5m/min. The hoisting accuracy is more suitable for precise hoisting operations; the dual-pump split-converging control technology has the highest composite action performance in the industry and efficient operation.

Due to the complex and diverse construction sites for 20-ton products, car traps and chassis scraping often occur. In order to help customers solve practical problems during use, the approach angle of the QY20K5C cab reaches 25 °, which is basically twice that of industry products. There will be no rubbing against the cab before the steep slope, and there is no need to disassemble the protection. The chassis has undergone a comprehensive system upgrade from the engine to the gearbox to the axle. The industry's first golden transmission chain system has a maximum climbing capacity of 47%.
