China QAY100A All Terrain Crane biggest mobile cranes
(1) excellent overall performance
1. Lifting performance: the boom is strengthened, with a special 11m jib for wind turbine working condition available, able to lift 65t weight at 72m height and meet the requirements of lifting 1.5MW wind turbine.
2. Driving performance: mature all terrain hydro-pneumatic suspension system is adopted, with multi-axle steering and driving modes available, offering flexible steering, strong driving performance and high pass-ability.
(2) efficient, reliable and upgraded systems
1. The hand acceleration and remote control device are newly added to the operation of superstructure, so as to reduce operator fatigue and enhance operation safety. Remote control distance can reach 150m, exceeding other competitors.
2. Super-lift is independently controlled, with more convenient luffing and tensioning.
3. A brand new counterweight attachment mechanism is adopted. Self-rigging counterweight saves the need of an assisting crane and cuts down installation cost. Counterweight assembly accuracy and efficiency are enhanced.
(3) Large-tonnage all terrain crane superlift technology
1. The frame 3 is newly added to the luffing jib, which optimizes the jib erection procedure, reduces the shock load to boom top, decreases operation time and improves working efficiency while enhancing safety.
2. The general braking management system, which is unique in the industry, is adopted to the chassis, improving braking efficiency, boosting driving safety control and reducing braking distance by 15%.
(4) all-around humanized design
1. A brand-new overall profile is of elegant appearance; the boom is designed with falling prevention and skid prevention to guarantee operator's safety while working on the boom.
