Feature QY50K truck crane's structure is compact, the industry operating performance is the highest. Lifting performance and driving performance of a comprehensive upgrade, leading competitors. Advantages and highlights: 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.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. 2. Waterproof connector clip is equipped with rubber sheath inside with excellent water impervious and level of protection reaches to IP65. The air-conditioning condenser is separately installed, the heat-sinking capability is sharply improved and the environment temperature reached to more than 45ºC. 3. 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 Parameters
