Product Introduction
The QAY160 is a 160-ton class all-terrain crane renowned for its formidable lifting capacity and exceptional all-terrain mobility. It features a six-axle all-terrain chassis with air-oil suspension and dual engines for both the upper and lower structures, delivering a maximum rated lifting capacity of 160 tons. Its basic boom delivers a maximum lifting moment of 5282 kN·m. The main boom extends up to 60 meters, while the combined main and jib boom reaches a maximum length of 80 meters. With a maximum lifting height of 79 meters, it offers extensive operational reach. Capable of traveling at speeds up to 71 km/h and climbing gradients of 48%, this crane ensures high relocation efficiency and adapts seamlessly to complex working conditions.
Product Advantage
1. excellent overall performance
* 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.
* 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
* 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.
* Super-lift is independently controlled, with more convenient luffing and tensioning.
* 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. Large-Scale Infrastructure Construction
Ideal for major construction sites like highways and bridges, handling heavy precast components, large steel structures, and other building materials. Its exceptional lifting capacity (160 tons) and extended boom configuration (main boom + jib reaching up to 80 meters) effectively cover large-scale, high-difficulty work areas.
2. Mining and Quarry Operations
Ideal for lifting large ore blocks, stone materials, heavy equipment components, and installing pipelines in mining and quarry sites. Its rugged chassis and formidable off-road capability (maximum gradeability of 48%)—combined with a six-axle all-terrain chassis and air-oil suspension system—ensure adaptability to rugged and harsh working conditions.
3. Oilfield and Energy Base Construction
In oilfield and energy project sites, it facilitates large equipment installation, heavy pipe handling, and maintenance support. Its powerful lifting capacity and environmental adaptability meet diverse construction demands.
4. Ports, Terminals, and Major Logistics Hubs
At ports, large warehousing bases, and logistics centers, it efficiently handles loading/unloading and transshipment of heavy cargo, large machinery, and materials. Its agile maneuverability (maximum speed of 71 km/h) and full-rotation capability enhance logistics efficiency.
5. Power Engineering and Emergency Response
Ideal for hoisting power towers, erecting power grids, and other large-scale equipment in power projects, as well as emergency response at disaster or accident sites. Its excellent stability (H-type outriggers) and reliable continuous operation capability address diverse urgent needs.
Product Operate Guide
QAY160 operation must be strictly standardized. Before commencing work, ensure all outriggers are fully extended and supported on solid, level ground. Continuously monitor the torque limiter during operation; overloading is strictly prohibited. Control boom movements smoothly via the control console, paying attention to the driving stability of its six-axle all-terrain chassis. During lifting operations, a dedicated signal person must direct the process, ensuring cargo is securely lashed and personnel are kept clear. After operation, fully retract and secure the boom, and perform regular maintenance.
FAQ
1. DOES THE PISTON ROD SURFACE OF THE HYDRAULIC CYLINDER EXHIBIT UNIFORM, SLIGHT WEAR WITH A SHINY APPEARANCE?
Normal. These are normal friction marks from contact with the guide sleeve seal.
2. ARE THERE SEVERAL CONSECUTIVE TEETH ON THE SLEWING RING SHOWING ABNORMAL WEAR?
Minor deformation in the slewing motor mounting surface or the slewing ring itself causes poor meshing.
3. DOES THE SENSOR SIGNAL VOLTAGE OCCASIONALLY DROP TO ZERO DURING OPERATION?
Loose connection in the sensor power supply circuit causes momentary disconnection during equipment vibration.
4. DOES THE RADIO OR AUDIO SYSTEM PRODUCE HUMMING NOISES DURING OPERATION?
Electromagnetic interference caused by worn generator carbon brushes or aged rectifier diodes. Inspect the generator and filter circuit.
5. MULTIPLE FAULT LIGHTS OCCASIONALLY ACTIVATE SIMULTANEOUSLY?
Loose or corroded ground connections in the vehicle's electrical system cause common-mode interference.
6. AUTOMATIC IDLE FUNCTION FAILS?
Check the pilot pressure detection switch or sensor under the control lever for faults, or verify if this function is disabled in the ECU.
