Product Introduction
The QAY650A prioritizes high-efficiency operation and intelligent safety. Equipped with a dedicated wind turbine boom head, variable jib, and dual-ratio Y-type superlift device, it delivers exceptional lifting efficiency. Its self-top counterweight hooking system enables rapid self-disassembly, saving auxiliary equipment and time. Featuring black box technology, touchscreen controls, and a fault diagnosis system, it offers user-friendly operation and high reliability.
Product Advantage
QAY650 all terrain crane is equipped with new spacious luxury cab, combined center console, digital indicator, Grammer air suspension seat, electrical control rear mirror, etc. The product adopts 8-axle chassis, 6-axle steering, and 4-axle drive, featuring sufficient power. 7-segment oval-section jib adopts the telescopic mechanism of the single-cylinder bolt. The full extension length is 84m. The product has many optional devices, such as 63m fixed extension jib, 95m luffing jib, expanding the working space.
Improve the super-lift device, and double the jib length. The lifting height increases 7×12m, and the lifting performance increases by 60%. Through the application of the Fieldbus technique, the computer integrated control technique improves the energy efficiency, failure diagnosis intelligence, and control automation. The product is equipped with the auxiliary winch which is specially used to install the big hook and steel wire rope. The dismantling of the optional devices, such as the counterweight, luffing jib, etc. can be completed by the machine itself, considering the convenience of the installment and dismantling to the maximum.

Product Uses
1. Wind Turbine Installation and Maintenance
The QAY650A is specifically engineered for the wind power market, with its dedicated wind turbine jib configuration capable of installing 2.0MW wind turbines. It efficiently performs maintenance and replacement of nacelles, blades, and other components in harsh environments such as high altitudes and low temperatures. Its 92-meter main boom, combined with superlift capability and a variable-reach jib, significantly enhances lifting performance and high-altitude operation.
2. Large-Scale Infrastructure Construction
Widely deployed at major construction sites for highways, bridges, and rail transit. Its extended boom configurations and exceptional lifting capacity effectively handle large-span, high-difficulty hoisting tasks.
3. Petrochemical and Energy Project Lifting
Demonstrates outstanding performance in petrochemical engineering, capable of lifting large equipment like flare stacks, external heat exchangers, heat exchangers, and reaction towers. Its robust stability and precise control system ensure safe positioning of critical equipment.
4. Municipal and Overseas Major Projects
Suitable for various major municipal projects both domestically and internationally. It has also been successfully applied in municipal construction projects in Brazil.
Product Operate Guide
The QAY650A features advanced technology (such as black box technology, touchscreen control, and self-diagnostic fault detection), but safe and efficient operation requires standardized procedures. Operators must be certified, conduct thorough equipment inspections before each job, and strictly adhere to the official load charts at all times. Overloading is strictly prohibited. Special attention to equipment maintenance is required when operating in harsh environments.
FAQ
1. HOW TO PROPERLY START MECHANICAL EQUIPMENT?
Check that all instrument readings are normal. Turn the key to the ON position and wait for the system self-check to complete. Then start the engine and let it idle for 3-5 minutes to warm up.
2. WHAT ITEMS ARE REQUIRED FOR DAILY MAINTENANCE?
Includes checking engine oil, hydraulic oil, and coolant levels; cleaning the air filter; inspecting tire or track condition; and tightening all connecting components.
3. HOW OFTEN SHOULD HYDRAULIC OIL BE REPLACED?
Generally every 2,000 operating hours or annually, but shorten the replacement interval under harsh operating conditions.
4. HOW SHOULD EQUIPMENT BE PROPERLY STORED?
Clean the equipment, fill fuel tanks, drain water from water tanks, apply rust prevention to exposed metal parts, and start the engine monthly for operation.
5. WHAT IS THE REPLACEMENT CYCLE FOR FILTERS?
Inspect the air filter every 500 hours and replace it every 1000 hours. Replace the fuel filter every 500 hours. Replace the hydraulic oil filter for the first time at 250 hours, then every 500 hours thereafter.
6. HOW SHOULD THE BATTERY BE MAINTAINED?
Keep the terminals clean. Regularly check the electrolyte level and specific gravity. Disconnect the negative terminal during extended storage. Charge the battery once a month.
