Product Introduction
The self-combination counterweight technique developed by ourselves can effectively improve the lifting performance by 30%. The electrohydraulic proportion control multi-axle steering mode can realize many kinds of steering modes. The new brake technique can reduce 2/3 maintenance cost, and improve the travel safety.
Product Advantage
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.
3.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.
4.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.

Product Uses
1. Wind Turbine Installation and Maintenance
This crane is ideally suited for wind turbine installation and maintenance operations. The QAY260A model has been specifically upgraded for wind power applications, featuring a dedicated configuration with a 62.8-meter main boom + 20-meter fixed jib and a 4.6-meter independent jib tip device. This setup effectively expands the lifting space, meeting the unique requirements of large wind turbines with demanding installation space needs, while significantly improving site relocation efficiency.
2. Mining and Quarry Operations
Suitable for lifting large ore, stone, and heavy equipment components in mining and quarry sites. Its 260-ton rated lifting capacity and excellent maneuverability (4WD design with 50% maximum gradeability) enable operation in rugged and challenging environments.
3. Large-Scale Infrastructure Construction
Widely deployed at major construction sites like highways and bridges for lifting heavy precast components and large steel structures. Its extended boom configuration (main boom + jib reaching up to 101.5 meters) effectively covers extensive, challenging work areas—such as installing precast elements in high-pile wharf projects.
Product Operate Guide
QAY260 operation must be strictly standardized. Before operation, ensure all outriggers are fully extended and supported on solid, level ground. Monitor the torque limiter throughout operation; overloading is strictly prohibited. Use the intelligent control system to smoothly operate the boom, paying particular attention to the application of its self-assembling counterweight technology. A dedicated signal person must direct lifting operations to ensure cargo is securely lashed and personnel are kept clear. After operation, fully retract and secure the boom, and perform regular maintenance. Operators must be certified.
