Product Introduction
The QAY1200 prioritizes high-efficiency operation and intelligent safety. Equipped with dual-mode operation, a dual-ratio Y-type superlift device, and self-dismantling technology, it enhances lifting efficiency and facilitates site relocation. Advanced features including an electronically controlled multi-mode steering system, multi-brake management system, and touchscreen integrated control technology ensure precise, safe, and reliable operation while supporting remote fault diagnosis.
Product Advantage
QAY1200 All Terrain Crane is designed mainly for erection and maintenance of 2.0-2.5MW wind turbines. It is also suitable for operation in typical working conditions such as lifting operation for bridges, high-rise buildings, and petrochemical construction. The pioneering dedicated wind power jib head is adopted. Boom and jib can be carried during heavy load jobsite transfer between wind turbines and no assistant vehicle is needed for the transformation between operation configuration and jobsite transfer configuration. Independent heavy-duty suspension system with single cross arm is applied, and the min. ground clearance can reach 530mm, which can meet the requirements of jobsite transfer in mountainous areas.
With modular design, flexible conversion between wind power version and standard version is possible, which makes the crane suitable for wider applications. The pioneering 6-axle mechanical drive is equipped with G1 large speed ratio hydraulic drive, forming superb 7 axles driven by double-power involved in driving.

Product Uses
1. Wind Turbine Installation and Maintenance
The QAY1200 is specifically engineered for the wind power market. Its dedicated wind turbine boom configuration efficiently handles installation and maintenance tasks for wind turbines up to 2.5MW. It operates stably in complex terrains like mountains and hills, with its powerful lifting capacity and exceptional working radius effectively resolving challenges where blades cannot be transported to installation sites.
2. Large-Scale Petrochemical Project Lifting
Widely deployed in petrochemical engineering for lifting large-scale equipment like reaction towers, methanol towers, and waste heat boilers. Its exceptional micro-movement control and precise maneuverability enable safe, efficient dismantling and assembly of heavy machinery within confined factory spaces—demonstrated notably in the Zhangzhou Gulai Chemical Plant project.
3. Power Plant Construction and Major Energy Projects
Suitable for construction, equipment installation, and maintenance in major energy projects like thermal power plants and nuclear power stations. Its formidable lifting capacity handles the demands of hoisting super-heavy and oversized components in these fields, such as heavy generator stators and boiler modules.
4. Bridge and Other Large Infrastructure Construction
Participates in large-scale infrastructure projects like highway and railway bridges, lifting massive bridge components and heavy steel structures. Its extended boom configurations and robust stability effectively fulfill demanding long-span and high-difficulty lifting tasks.
5. Rail Transit and Special Conditions
Suitable for lifting large precast beams or equipment in rail transit projects. Its multi-axle drive and all-wheel steering system provide excellent road adaptability and maneuverability, meeting the stringent demands of construction sites.
Product Operate Guide
QAY1200 operation must be strictly standardized. Before commencing work, ensure all outriggers are fully extended and supported on solid, level ground. Monitor the torque limiter throughout operation; overloading is strictly prohibited. Control boom movements smoothly via the control console, leveraging the precision offered by its advanced hydraulic system and electronic control technology. During lifting operations, a dedicated signal person must direct 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.
FAQ
1. WHAT ASPECTS REQUIRE ATTENTION DURING ROUTINE MAINTENANCE?
Regularly check all fluid levels and oil quality, clean the air filter, and inspect the tightness of bolts throughout the machine.
2. WHAT PRECAUTIONS SHOULD BE TAKEN FOR LONG-TERM STORAGE?
Park the equipment on level ground, retract all cylinders, disconnect the negative battery terminal, and apply rust prevention measures.
3. HOW TO ADDRESS WEAK TRACTION?
Check transmission fluid level and inspect for clutch or torque converter malfunctions. Top up transmission fluid and service the drivetrain.
4. HOW TO RESOLVE HEAVY STEERING?
Verify steering hydraulic system pressure and inspect the steering gear for faults. Adjust system pressure and service the steering gear.
5. WHAT CAUSES EXCESSIVE HYDRAULIC SYSTEM NOISE?
Typically due to insufficient hydraulic fluid, degraded oil quality, clogged suction filter, or air ingress into the hydraulic pump. Check fluid level, replace hydraulic oil and filter, and eliminate air leaks in the intake lines.
6. WHY DOES THE EQUIPMENT VEER OFF COURSE DURING TRAVEL?
Check if tire pressures or track tensions are consistent, if the braking system exhibits unilateral drag, or if the transmission system is malfunctioning.
