QY55KC Truck crane is widely used for the lifting operations in general engineering projects, such as construction sites, urban renewal, communication and transportation, ports, bridges, oilfields and mines, and complex working environments.
1. Superb lifting performance
5-section boom of 44.5 m with U-type profile, best-in-class boom length. The max. parts of line for the main hook block is 12. The crane has leading capacities with full counterweight compared with the competitive cranes. The telescoping mode is updated to random telescoping from sequential telescoping, resulting in more efficient change of boom length, and better capacity of medium-long boom.
2. Constant displacement pump valve-controlled load sensitive hydraulic system
Oil supply may be switched from dual-pump to single pump for precise operation. The min. stable slewing speed of 0.1°/s and min. stable lifting speed (at drum) of 2.5 m/min contribute to precise and safe lifting operations.
3. Power transmission system
Sinotruk engine with rated power of 276kw, and max torque of 1560 N.m.
Max. travel speed is 90 km/h, and max. gradeability is 45%.
4. Optimal power transmission system
High power performance and low fuel consumption are perfectly integrated. The max. grade ability is 45%, max. travel speed is 90 km/h, and fuel consumption per 100 km is only 40L.
