XCMG Qy12b. 5I 12ton hydraulic folding truck crane.
1,More excellent performance
• The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
• Apply the mature jib technique which integrates plug-in boom head, embedded boom block, and special telescoping mechanism, which makes the jib more stable and reliable.
• Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
2,More reliable quality
• Adopt the classic K series jib telescoping technique, working safer and more reliable.
• Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
• The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
• The new power steering mechanism adopts hydraulic power design, which makes the steering light, flexible, and precise, and ensures the safety of the truck.
• The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
• The perfect integration of the design and structure realizes the automation of welding, which is more reliable.
3,Easier to operate
• The high efficient and energy efficient load sensing hydraulic system is sensitive to operate and precise to control, having good slight mobility.
• Optimize the control levers, which is easier to operate.
• The cab adopts orthodrome front windscreen, having wider operating views.
4,Easier to maintain
• The optimizing design of the pipeline traces makes the layout more scientific and reasonable, greatly reducing the dismantling and installing time of the pipelines and the maintenance expense.
• Completely upgrade the electrical system. Adopt anti-creep connector clips, greatly prolonging the service life of the parts.
• Adopt K series rope anti-disorder technique, improving the lifting efficiency, reducing the labor intensity, and prolonging the service life of the steel rope.
• The telescoping steel wire rope oriented and protective device avoids the steel wire rope out of the track and broken.
• Fully covered walking plate supplies a platform for the maintenance, and effectively protects the parts of the machine.
