QAY25 All Terrain Crane is designed and manufactured by Xuzhou Heavy Machinery Works XCMG with its many year’s successful experiences in manufacture of truck crane, in absorption of foreign high-tech and combined with the development of international all terrain crane. It is designed with computer in 3D configuration. The crane has the advanced technology including open type variable displacement system, hydraulic proportional control, hydro-pneumatic suspension and multiple chord boom profile. It features outstanding performance of load lift and road travel, not only meet the need of ordinary customers at home and abroad but also is suitable for use in western plateau, oil-field, semi-desert, etc., particularly for narrow site and rough road. It is truly an all terrain crane suited to the conditions in China.
Xuzhou Heavy Machinery Works XCMG is the leading manufacturer in China’s construction crane industr
