XCMG QY50KA Truck Crane.
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.
Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
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 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.
