Advanced development analysis means make sure design is very reliable.
The structure design is more compact,lighter self-weight, greater load ratio , the whole line is reasonable, beautiful.
Higher lifting capacity with four connected bar mechanism.
Two folding arm can tit upward(negative elevation angle), so that the crane can enter the lower working space for lifting.
The second section knuckle boom cylinder with reverse arrangement and adopt the flange connection balance value with higherreliability to reduce the leakage point. There is no oil pipe on the oil cylinder tube to reduce the possibility of damage
Rack cylinder adopted inclined arrangement, boom in folding state to make full use of space , compact overall structure.lowercenter of gravity and vehicle driving stability.
The more symmetrical center design of hexagon boom make it has bigger anti-bending capacity.
The float three-point bridge structure design can lower the accessional stress on the chassis frame when traveling
