1.The second section knuckle boom cylinder with reverse arrangement and adopt the flange connection balance value with higher reliability to reduce the leakage point. There is no oil pipe on the oil cylinder tube to reduce the possibility of damage
2.Rack cylinder adopted inclined arrangement, boom in folding state to make full use of space , compact overall structure.lower center of gravity .
3.The more symmetrical center design of hexagon boom make it has bigger anti-bending capacity.
4. Advanced development & analysis make sure design is very reliable
5. The structure design is more compact, lighter self-weight, greater load ratio, the whole line is reasonable, beautiful.
