XCMG QY50K-Ⅱ crane adopts innovative boom system, adopts patented technology of embedded slider and plug-in boom head and internationally advanced "U" shaped cross-section boom, with excellent lifting performance and safe and reliable lifting work.
Proprietary telescopic technology avoids the occurrence of core tube bending, cylinder bending, and boom breakage caused by misoperation, thereby improving operational safety.
Eight patented technologies ensure the smoothness, high efficiency and energy saving of the lifting, slewing and luffing mechanisms.
The use of a new hydraulic motor with a large starting torque makes the secondary lifting operation safer.
Humanized design of the cab and control room, with more space and flexible and easy operation.The control room adopts a large arc front windshield, which provides a wider control field of vision.The efficient and energy-saving load-sensitive hydraulic system is sensitive and comfortable to operate, with precise control and good micro-movement.
Energy-saving and more environmentally friendly.The engine adopts dual industrial control mode, which is powerful, economical and energy-saving.In economic mode, it can meet the demand for engine power of conventional hoisting operations, and in high-power mode, it can effectively support the requirements of high-difficulty and high-efficiency hoisting operations.
