XCMG truck crane QY70k-I construction

Product catalog summary

Product Advantages:
The QY70K-I Truck Crane features eight patented technologies that enhance the efficiency and safety of its lifting, slewing, and luffing mechanisms. It includes a large displacement motor for single-lift operations and a new hydraulic motor for safer second-lifting operations. The innovative boom system with patented technology ensures excellent lifting capacity and reliability.

Hydraulic System:
The crane uses a loading sensitive system that maintains normal hydraulic oil temperature for stable operation and long service life. The hydraulic heat radiation system allows operation in ambient temperatures exceeding 55°C, improving working efficiency by 10%.

Structural and Design Features:
The crane's boom system includes inserted sliders and an octagonal-shaped cross-section for enhanced lifting performance. The ergonomic design of the operator's cab provides comfort and flexibility. The paint used offers improved ageing resistance, and the crane is equipped with high-temperature resistant sealing elements.

High-Temperature and Dusty Area Adaptations:
The crane is designed for high-temperature and dusty environments, featuring a high-power air-conditioner, multi-stage air inlet filtering system, and efficiently sealed cabs. The wiring harness is heat and ageing resistant, and the crane uses high-temperature resistant oil.

Technical Specifications:
The crane has a total length of 13,930 mm, a width of 2,800 mm, and a height of 3,575 mm. It operates with a Euro III Hangfa WD615.338 engine, providing a rated output of 276 kW at 2200 r/min. The maximum travel speed is 80 km/h, and it has a maximum lifting load of 70 tons.

Lifting Performance:
The crane's lifting performance is detailed with various configurations of the boom and outriggers, specifying the total rated lifting load for different boom angles and extensions. The crane can operate under wind conditions up to level 5, with specific guidelines for using the main boom and luffing jib.
