Highlight 1: Leading lifting and driving performances 1. Five section U-type booms. The boom length is 11.4m-43.5m with strong lifting performance, leading 5%-10% ahead of products with the same tonnages in the same industry. 2. High-power engine with good dynamic performance, strong gradeability and superior trafficability. The maximum gradeability and maximum travel speed respectively are 42% and 85km/h. Highlight 2: Reliability of heat dissipation, electrical system etc. has been improved with safer operation and driving 1. Waterproof connector clip. It is equipped with rubber sheath inside with excellent water impervious and level of protection reaches to IP65. 2. Aluminium alloy fuel tank. Good appearance quality, corrosion resistance, strong shock resistance capacity. 3. Double- broken line winch. The hoisting rope is in alignment, and it will be more reliable if turn off the press-rope machine. 4. Optimized heat-removal system. The air-conditioning condenser is separately installed, the heat-sinking capability is sharply improved and the environment temperature reached to more than 45℃. Highlight 3: Mature and reliable double-pump confluence technique, maintaining the advantages of efficient operation Special confluence multi-valve has been designed. The double-pump confluence technique is adopted in raising and falling of winch, extending and retracting of lazy boom and luffing, leading ahead of luffing and extending and retracting operations. Highlight 4: Air-aid shift gears and 45% of shifting force is reduced Special air-aid shift gears protection mechanism. The boost system will work only by stepping on the clutch that effectively avoids gearbox damaging gears when shifting. Compared with the same industry, 100mm distance of shift gears and 45% of shifting force are respectively reduced. Highlight 5: Appearance molding is newly upgraded, humanized design and comfortable riding manipulation New operating house, wheel house, engine hood and machine shed, novel appearances, fine lines of the complete machine appearance, shows its elegant appearance. The rearview mirror is installed in operating house, easy to for observe the working environment; front pedal and push-and-pull pedal in left side are installed, easy access to the operating house; Ladder stand is installed in two sides of the chassis, easy to get on or off the bus. In addition, tool cabinet is installed in right rear side of the frame, easy to store tools attachment for users, fully representing the purpose of humanized design.
