Official Manufacturer Qy25K Hydraulic 25 Ton Mobile Cranes Truck Mounted Crane for Sale

QY25K5A truck crane is the product with high reliability inheriting classical and advanced technology aboutdesign and manufacture truck crane of many years and based on mature technology.
Special truck crane chassis designed and manufactured by our company,all covered working surface and new appearance outline are equipped.Theoperations of craneare very simple,convenient and flexible.It is widely used for lifting operation and installation work in urban renewal, transportation, ports, bridges, oilfield, industrial and mining enterprises, etc.

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 effectivelyrealizesenergy-saving.The counterbalance valve adopts over-load compensated technology to ensure crane fallsmoothly. Equipped with new hydraulic variable displacement motor with large original torque to ensure noglidingduringsecond-lifting, improve working efficiency.
