Product Advantage
More excellent performance
• The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
• Apply the mature jib technique which integrates plug-in boom head, embedded boom block, and special telescoping mechanism,which makes the jib more stable and reliable.
• Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
More reliable quality
• Adopt the classic K series jib telescoping technique, working safer and more reliable.
• Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
• The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
• The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
• The perfect integration of the design and structure realizes the automation of welding, which is more reliable.

Product Uses
1. Infrastructure Construction in Plateau Regions
The QY80KH has been specially optimized for the oxygen-deficient environment of plateaus, effectively overcoming power attenuation issues. It is highly suitable for highway, railway, bridge, and tunnel construction in plateau regions, capable of stably and efficiently completing tasks such as steel structure hoisting and precast component installation, ensuring the progress of infrastructure projects in high-altitude areas.
2. Transportation Hubs and Municipal Engineering
This crane is widely deployed in transportation infrastructure like roads and bridges, as well as municipal engineering projects. Its robust lifting capacity and excellent maneuverability efficiently handle large component hoisting and equipment installation, meeting lifting demands in urban renewal and similar applications.
3. Industrial Sites and Energy Projects
The QY80KH facilitates large-scale equipment installation, maintenance, and relocation within industrial facilities. Its outstanding environmental adaptability also enables it to handle lifting tasks in high-altitude or mountainous energy project developments.
4. Operations in Confined or Complex Sites
With its relatively compact overall design and flexible operability, the QY80KH adapts to space-constrained conditions like narrow urban streets and factory premises, facilitating equipment hoisting and maintenance operations.
Product Operate Guide
Before operation, thoroughly inspect the high-altitude adaptation configuration status and verify the normal functioning of the engine intake system and hydraulic system. Maintain absolute levelness of the crane during operation and strictly prohibit overloading. Monitor engine power reduction in high-altitude regions and appropriately reduce operational intensity. Operate the boom with exceptional smoothness, paying attention to wind load effects at high elevations. Regularly inspect the air filter and monitor hydraulic oil temperature. After operation, retract the boom, implement equipment freeze protection measures, and maintain detailed records of high-altitude operating data.
FAQ
1. HOW SHOULD LIFTING POINTS BE SELECTED DURING EQUIPMENT TRANSPORTATION?
Always consult the manual and use only lifting points or transport holes explicitly marked by the manufacturer. Never secure loads to cylinder rods, hoses, or thin steel structures.
2. SHOULD THE ENGINE NOT BE SHUT DOWN IMMEDIATELY AFTER PROLONGED HEAVY-DUTY OPERATION?
Correct. Allow the engine to idle for 3-5 minutes to ensure uniform cooling of the turbocharger and engine, preventing localized overheating damage.
3. HOW TO DETERMINE IF HYDRAULIC OIL NEEDS REPLACEMENT?
Simple method: Place a drop of used oil on filter paper. If the dark spot at the center has a clearly defined boundary with the outer diffusion ring, it indicates high impurity levels and requires replacement.
4. ENGINE POWER DECREASED AFTER REPLACING THE AIR FILTER?
Check the air filter assembly for proper sealing or verify the filter element model. Inferior elements may cause increased intake resistance.
5. ENGINE FAN AIRFLOW FEELS WEAK?
Check if the fan clutch has failed, or if the motor/pump for the hydraulically driven fan is malfunctioning.
6. OIL STAINS AT THE TURBOCHARGER CONNECTION?
Normal. Turbocharger bearings rely on engine oil for lubrication. Minor oil vapor seepage is common as long as it doesn't form drips.
