Product Introduction
QY110KH is the first four-wheel driven truck crane domestically, which can meet the need under various road conditions.Chassis rear hydraulic controlled follow-up steering technology, realizate highway and small turning two steering modes, ensure stable and reliable of vehicle at high speed, travelling at lower speed is flexible.
Product Advantage
7-section boom of 72 m with U-type profile is adopted; the max. lifting load is 100 t; the max. lifting height is 97 m; the performance takes the lead comprehensively.
Low speed large torque power transmission system, contributes to perfect combination of optimal power and optimal economical efficiency, leading to more than 12% reduction in fuel consumption and 10% improvement in grade ability.

Product Uses
1. Infrastructure Construction in Plateau Regions
The QY110KH features an engine and hydraulic system optimized for plateau hypoxia, effectively overcoming power loss issues. It is ideally suited for highway, railway, bridge, and tunnel construction in plateau areas, delivering stable and efficient performance in tasks such as steel structure hoisting and large precast component installation, thereby ensuring progress on high-altitude infrastructure projects.
2. Energy Projects and Large Industrial Equipment Installation
This crane supports development and maintenance of energy projects—including mining, petrochemical, and power facilities—in high-altitude or mountainous regions. Its formidable lifting capacity and resilience to harsh environments enable it to handle demanding tasks like heavy equipment hoisting and large component installation.
3. Lifting Operations in Harsh Climates and Remote Areas
The QY110KH features specialized design for extreme conditions including high winds, sandstorms, significant temperature fluctuations, and sub-zero temperatures. This ensures high availability and reliability in remote, windy, sandy, or frigid environments, enabling it to handle diverse lifting tasks.
4. Transportation Hubs and Large-Scale Municipal Projects
This crane is also suitable for diverse large-scale construction projects in non-high-altitude regions, such as port terminals, major bridges, and urban landmark structures. Its robust lifting performance and excellent maneuverability enable efficient completion of tasks like large-component hoisting and equipment installation.
Product Operate Guide
Before operation, thoroughly inspect the high-altitude adaptation configuration status to ensure the engine intake system and hydraulic system are functioning normally. 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. WINDSHIELD WIPERS ONLY OPERATE AT HIGH SPEED?
Damaged low-speed contacts in the wiper control switch or related wiring faults.
2. UNEVEN ROTATION SPEEDS BETWEEN LEFT AND RIGHT WIPERS?
Asymmetrical oil supply pressure to the rotation motor, differing settings on the rotation buffer valve, or mechanical resistance differences.
3. HYDRAULIC FLUID BECOMES DIRTY AGAIN SHORTLY AFTER REPLACEMENT?
Insufficient cleaning of the reservoir and lines during fluid change, or the bypass valve on the replacement filter remains open, allowing contaminants to recirculate.
4. HYDRAULIC CYLINDER ROD SHAKES DURING EXTENSION?
Air ingress into the rodless chamber or slight bending of the piston rod. Requires bleeding or professional calibration.
5. UNEXPLAINED RISE IN ENGINE OIL LEVEL?
Serious issue! Coolant (damaged cylinder head gasket) or diesel fuel (injector failure) leaking into the oil pan. Immediate inspection required.
6. ENGINE FAN AIRFLOW FEELS WEAK?
Check for fan clutch failure or malfunction in the hydraulic drive motor/pump.
