1. Outer boom can enter tilt upward(negative elevation angle), so that the crane can enter the lower working space for lifting.
2. Flage telescopic boom coupling technology.
3. Rack cylinder adopted inclined arrangement, boom in folding state to make full use of space, compact overall structure, lower center of gravity and vehicle driving stability.
4. The more symmetrical center design of hexagon boom make it has bigger anti-bending capacity.
5. Float three-point bridge structure design can lower the accessional stress on the chassis frame when traveling
