Truck Crane Advantages and Highlights
XCMG truck crane's structure is compact, the industry operating performance is the highest. Lifting performance and driving performance of a comprehensive upgrade, leading competitors. Dual-pump confluence technology, operating efficiency of a comprehensive lead.
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.
The features of XCMG Truck Crane
• The innovative jib system adopts embedded block, plug-in boom head and international advanced U section jib, which has excellent lifting performance and safe and reliable lifting work.
• The unique stretch and retract technique avoid the bend of the core pipe and cylinder and the break of the boom caused by mis-operation, improving the safety of the operations.
• Eight patent techniques ensure the smooth, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
• The torque limiter adopts colorful LCD display, realizing the intelligence of the failure diagnosis. The precision is ahead of the industry.
• Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer.
Xuzhou Construction Machinery Group Co., Ltd. (XCMG) was founded in 1943. Since then, XCMG has stood at the forefront of the Chinese construction machinery industry and developed into one of the domestic industry's largest, most influential, and most competitive enterprise groups with the most complete product varieties and series.
- GREEN TECHNOLOGY: As a leading enterprise in China's construction machinery industry, XCMG has transcended the traditional business philosophy of putting profit before all else in order to meet its economic and moral responsibilities by emphasizing its contributions to customers, employees, partners, the environment, and society, and dedicating itself to green manufacturing, green R&D, environmental protection, energy conservation, reducing emissions, and developing a circular economy, all of which exemplify the company's strong sense of social responsibility.
- Hybrid Technology: XCMG pooled its technological advantages to carry out in-depth studies on gasoline-electric hybrid engine systems and actively apply it to product R&D. This system converts pressure from the swing overflow and main pump overflow into electric energy, which is transmitted to the motor to provide auxiliary power.
