Audited Supplier More excellent performance:
• The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performanceis 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.
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.
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.
