Product Description.
QY70V532 75ton Hydraulic Mobile Truck Crane
1.High performance
Overall optimized matching technology is adopted with high strength boomand optimized aspect ratio, which reduces boom torsion, side-bending, etc. Newsingle-cylinder pinning telescoping system brings higher telescopingreliability. Inserted sliders may efficiently increase the overlapping lengthof adjacent boom sections and eliminate point contact or line contact betweenslider and boom, thus local buckling phenomenon is effectively avoided. Compactboom tail structure improves boom telescoping ratio, which effectively contributesto longer boom length. The boom with six sections can be extended up to 64m, 1mhigher than the longest boom in the class in the industry, with performanceimproved by 15~20%.
2.Energy-saving
Equipped with high-precision sensors and large power radiator, newenergy-saving hydraulic system adopts large displacement electric proportionalvariable pump with intelligent engine control technology to achiece higherenergy utilization, lower heat production, improved system reliability and 15%fuel conservation.
3.Intelligent
The latest control technology platform is adopted to update the system withthe realization of intelligent crane operations and travel control, such asautomatic planning of working conditions, winch servo control technology,lifting elevating compensation control technology, and other in-house developedintelligent boom technologies, contributing to improved automation of boomcontrol and higher lifting safety to a large degree.
Road traveling and tight turning radius modes are available throughrear-axle hydraulic control servo steering technology to ensure stablehigh-speed driving and flexible low-speed driving.
