 QAY220 all terrain crane, which integrates our many years’ experience in designing and manufacturing mobile cranes with internationally advanced technology, is a fine-performance and high-reliability product produced to meet the market demands. This high-tech product, combining mechanical, electrical and hydraulic systems as a whole, has so many advantages, such as good control performance, excellent jogging performance, large lifting capacity and super lifting height, that it can be applied in many fields of national economic construction. This product can be widely used in chemical industrial and mining establishments, oil fields, harbors, building sites except strong electromagnetic wave area to do lifting and hoisting work.

This product is an all terrain crane of full range slewing function, telescopic boom sections and electro-hydraulic proportional controlled systems. This product adopts 6-axle (4 driving axles and 5 steering axles) special purpose chassis manufactured by Zoomlion, providing wide vision, spacious cab and luxurious equipments.

The latest electro-hydraulic proportional directional control valve with load feedback function, multiple plunger variable pumps, open / closed variable systems ensure that each executive mechanism makes full use of its working capability. The joysticks which are easy-controlled, flexible, reliable and stepless speed regulated can provide the crane with smooth simultaneous movements, which greatly improves the working efficiency. The safety devices, such as relief valve, balance valve, hydraulic lock and brake valve, fitted in hydraulic system prevent the accidents caused by oil line overload and oil pipe breakage.

The safety devices, such as load moment limiter and lighting systems ensure your safety during operation and are convenient for night work.
