Main technical features:

1. CQUY550 hydraulic crawler crane adopts the advanced engine of Cummins QSB6.7 Diesel Engine. Up to Euro III emission standard, with advantages of the reliable power and economy.
2. Open type pump controlled variable system, constant power control, independent heat dissipation.

3. Both the main and the auxiliary lifting winch has equipped with unique free fall function. The max pull capacity in single lay can achieve 12t. Service grade designed according to M7 level, both winches can be  worked simultaneously with less fuel consumption and more effective operation.
4. The hydraulic system has adopted the Rexroth hydraulic components with the high reliability, stable operation and low failure rate.

5. Boom backbone tube adopts high-strength thin boom steel tube with the light weight and high loading capacity, which greatly lifting capacity.
6. Through the composition of different booms, the length of the main arm could reach 52m, and it could install 9.15m, 12.20m or 15.25m accessory booms when the length is 42m, the fixed angles of the accessory booms are 10°or 30°.
7. Telescopic chassis structure that can improve the stability and easy for transportation. The truck frame and the under frame adopt plugin connection, which is easy to assembly. The transportation weight of the parts is light; the transport weight of largest part is not more than 31t.
8. The new type cab with the wide views, it is equipped with top grade seat, and air-conditioning system, Car DVD system, provides driver comfortable operation and pleasured working environment.

9. To realize beltloading move on account of the powerful traction.

10. Equipped good quality steel wire rope and lengthens the service life.
11. Advanced Swing float function makes operation more steadily and safety.

12. The single sheaved block is equipped to realize light and quick lifting, which improves the work efficiency.
 
 

Brief Introduction of CQUY550:

In order to meet the market demands and improve product's cost performance, our company designed the crawler crane for the high-end users based on the many years of construction machinery’s production experience. This product has a good lifting performance, 360° turning and telescopic crawler. The length of main boom is 13—52m, length of fixed auxiliary boom is 9.15—15.25m.
 CQUY550 Crawler crane has strong hoisting capacity, big lifting weight, good anti-slip property, lower roadbed requirement. which is widely used for the big factory construction working such as petrochemical industry, electricity, metallurgy, chemical industry and nuclear energy.
