30ton Hydraulic Mobile Truck Crane QY30K5C
1. Leading lifting and driving performances
* 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. Reliability of heat dissipation, electrical system etc. has been improved with safer operation and driving
* 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. Mature and reliable double-pump confluence technique, maintaining the advantages of efficient operation
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.
4. Air-aid shift gears and 45% of shifting force is reduced
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.
