March 31, 2012

At 14:00 March 27, 2012, the Presentation Ceremony of " China Engineering Machinery TOP 50 Products of the Year Award 2011" was held in Beijing. 50 construction machinery products of outstanding performance in three dimensions, namely, technological innovation, market performance and application contribution, gained positions on the list of "2011 China Engineering Machinery TOP 50 Products of the Year". Beating the flat market situation, the products won great acclaims from the evaluation panel and industry at large.
QAY800 all-terrain crane is a well-balanced machine with a compact structure, elegant shape, strong lifting capacity and a wide range of performance capabilities. The machine features a 8-axle chassis, 4 axle drive and all-wheel steering, boasting a variety of steering forms with small turning radius and superior driving performance.QAY800 all-terrain crane has seen the development of a crane superlift technology, multi-section box boom cylinder bolt stretching technology, multi-axis heavy Vehicle pneumatic suspension technology, overloaded-Vehicle multi-axis multi-mode steering control technology, crane electro-hydraulic proportional control technology, integrated brake management technology for large multi-axis Vehicles and the multi-loading condition, multi-mode, multi-modular intelligent control technology.
QAY800All-terrain crane made a breakthrough in super-large tonnage crane arm self-disassembly technology with the development of a rope hanging structure that overcomes the bottleneck of balanced re-hanging for large tonnage cranes; a multi-faceted variable control room which expands the operation horizon and safety of hoisting operation; the independent closed-loop cooling technology; an engine cooling system of the largest power for domestic road usage; the designing of a dislocation compensation structure and solving the issue of wide span X-shape outrigger deformation.
The development of QAY800 all-terrain crane has raised the all-terrain crane product technology to a new level, which can effectively replace the imported models, introducing the entire product spectrum upgrading and making significant contribution to the industrial restructuring process. Can be directly or indirectly applied in cranes, cars and agricultural machinery products, the product’s research results will play a catalytic role in the related industries, as well as promote the development of iron & steel, coal, power generation and petrochemical industries. Having been tested by the National Construction Machinery Quality Supervision and Inspection Center, all dimensions of the entire QAY800 machine are found to have met with the requirements of the technology mission’s statement and related standards, and the safety and environment-friendly dimensions, the national mandatory standards. The product achieves 2 national invention patents, 8 utility model patents, 1 exterior patent, 11 national invention patents pending and 14 utility model patents pending.
