QAY240

QAY 240 is another new all terrain product developed by our company through extensive market research and technical demonstration. It inherits the successful experience, and adopts new materials, new technologies, and the most advanced steed structure design and computer control technique. The main hydraulic parts and load bearing materials adopts international parts and components, effectively improving the product’s performance and reliability. The application of hydropneumatic suspension all terrain chassis, electronic proportional control system, limit load control variable hydraulic system, U jib technique greatly improving the performance and grade of the machine. The machine has modern design, compact and reasonable layout, and excellent travel and lifting performance. QAY240 which represented the highest design level at that time attended the 2007 Munich Bauma Exhibition. It is the first time for the Chinese high-level crane shown on the international stage, extending the domestic crane’s influence in the world.
