QAY All Terrain Crane is a new style of All Terrain Crane designed basic on the successful design of QAY130, QAY160 and Qay200 ; it was after the extensive Market Investigation and technical proof, also based on the market realities. The products inherited the successful experiences of other All Terrain Crane, it adopted the new material, new Craftsmanship, and the most advanced steel structure design and computer technology in the present world. The main crucial of hydraulic component and load bearing material adopted internationalization mating, raised the product’s performance and reliability effectively. With the use of all terrain crane chassis by hydro-pneumatic suspension, electro-hydraulic pilot proportional control, critical load control quantity hydraulic system. U-shaped boom technology, it raised the performance and products levels. Design novel of complete machine, entire allocation is compactness reasonable, high performance of driving and lifting.
