Zoomlion Used All-Terrain Truck Crane Zoomlion QAY350 Ton Second Hand Crane
 
Production Details:

• Zoomlion QAY350 all-terrain all-terrain crane is a high-performance and high-reliability crane designed and developed by our company in order to meet the market demand, using the technology of designing and manufacturing mobile cranes for many years and combining with international advanced technology.
• This product is a high-tech product with a high concentration of electromechanical hydraulic systems. It will be active in various fields of my country's economic construction with its excellent handling performance, excellent fretting performance, huge lifting capacity and extraordinary lifting height.
• This product is suitable for lifting operations and installation projects in chemical, mining, oil fields, ports, construction sites and other places. This product is not suitable for areas with strong electromagnetic waves.
• This product is an all-terrain crane with full swing, telescopic boom type, electro-hydraulic proportional control. It adopts the company's self-made six-axle dedicated all-ground chassis, with wide field of vision, luxurious and comfortable decoration, four-axle drive and five-axle steering.
• The latest electro-hydraulic proportional reversing valve with load feedback and multi-piston variable displacement pump is adopted, and the variable system combined with open type and closed type is adopted, so that the working ability of each actuator can be fully exerted.
• The combined action of lifting, luffing, slewing, and telescopic mechanisms greatly improves the working efficiency of the crane. It has the characteristics of light and flexible operation, stable and reliable work, stepless speed regulation and so on. In the hydraulic system, there are safety devices such as relief valve, balance valve, hydraulic lock, brake valve, etc., to prevent the overload of the oil circuit and avoid accidents caused by the rupture of the oil pipe.
• Equipped with a variety of safety devices such as torque limiters and a complete lighting system, it can ensure safe and reliable operation and facilitate night work.
• This car was manufactured in 2013, with complete accessories, standard model, no overhaul, original original paint, excellent performance, you can inquire if you need it.
