1.Two folding arm can tit upward(negative elevation angle), so that the crane can enter the lower working space for lifting.
2.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
3.Rack cylinder adopted inclined arrangement, boom in folding state to make full use of space , compact overall structure.lower center of gravity.
4. Independent design deform ability, various parameters of the whole crane can be adjusted according to customer requirements to meet customer needs, and new products can also be designed and manufactured.
