China Crane Truck Qy50K-II Telescopic Boom Truck Crane in Good Condition

China Crane Truck QY50K-II telescopic boom truck crane in good condition
More excellent performance
1)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.
2)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.
3)Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
More reliable quality
4) Adopt the classic K series jib telescoping technique, working safer and more reliable.
5)Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
6)The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
7)The new power steering mechanism adopts hydraulic power design, which makes the steering light, flexible, and precise, and ensures the safety of the truck.
8)The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
9)The perfect integration of the design and structure realizes the automation of welding, which is more reliable.
Easier to operate
10)The high efficient and energy efficient load sensing hydraulic system is sensitive to operate and precise to control, having good slight mobility.
11)Optimize the control levers, which is easier to operate.
12)The cab adopts orthodrome front windscreen, having wider operating views.
