1. U-shaped cross-section boom has small depth-width ratio, strong bearing capacity, small deformation,strong anti-bending and powerful lifting capacity.The main boom length is 10.6m to 41.0m, the performance of mid-extended boom and fully-extended are also superior.

2. Plug-in boom head effectively increases theboom connect length andreducesboom deformation.Embedded sliders are equipped, which enlarge the contact square and reduce the contact stress of boom.

3. With 9-speed transmission equipped, it has superior travel and grade ability. The max. grade abilityis 40%, max. travel speed is 90km/h.

4.Open type fixed displacement pump and variabledisplacement motor system is adopted.Double pump confluenceis used in main operation, which meets the requirements of speed and reduces the energy consumption and system heat effectively. The load sensitive system that researched anddeveloped by ourselves contributes to smooth operation, high efficiency and energy saving.Particularslewing technology realizes smooth slewing and no jitter. Free fall is adopted in the elevating system,which effectively realizes energy-saving.The counterbalance valve adopts over-load compensated technology to ensure crane fallsmoothly.
