Brief Description
The CLM01 runway friction tester is designed for measuring the friction coefficient of airport runways. It is a specialized ground support device essential for ensuring the safe takeoff and landing of aircraft, and it has been officially approved as dedicated equipment for civil airports. This system is equipped with an automated computer-based measurement unit, an integrated water tank, and a spraying system. It offers broad adaptability and can be used on both concrete and asphalt runway surfaces. The system supports continuous automatic spraying and measurement over distances of no less than 7,000 meters, and it is capable of operating in rainy and snowy weather conditions.

Safety Design Concept
The vehicle’s original chassis frame, suspension system, fuel system, and ABS braking system remain unmodified, ensuring the overall safety, performance, and quality of the vehicle. The recessed section of the trunk has been reinforced and fitted with the complete testing system. This modification not only preserves but further enhances the structural integrity of the vehicle. Our philosophy: “Buying a good vehicle is just the beginning — using it well ensures both safety and efficiency.
Reliability and Technological Advancement
We have accumulated many years of experience in the design and development of friction coefficient testing equipment, along with extensive data analysis from airport applications and valuable feedback from end users. The system utilizes an industrial-grade laptop with a fully Chinese-language interface tailored to China’s operational environment, enabling it to withstand more demanding working conditions and significantly enhance product reliability. All selected components and materials are of the highest precision and grade among similar products, and have undergone rigorous inspection and testing to ensure the accuracy and reliability of the friction coefficient testing equipment.
Acceleration Performance
Equipped with powerful engines, the Ford Taurus 2.7T, Honda Acura, and BYD Tang offer rapid acceleration, reaching the testing speed of 96 km/h within 200 meters.
Computer-Controlled Operation
The system features an industrial-grade touchscreen laptop running a Chinese-language Windows operating system. The testing software employs a Chinese drop-down interface. The computer supports programmable operations and allows continuous testing of friction coefficient values ranging from 0 to 1.0.
Water Spraying System
The spraying system includes a water tank, pump, water pressure sensor, valves, fittings, and a regulation system. The tank is made of engineering-grade polypropylene, with a capacity of 580L or 620L, supporting continuous water spraying over a distance of no less than 7000 meters.
Test Tire
The equipment uses a specialized grooved test tire compliant with CAAC, ICAO, and FAA standards. The tire is made from the same material as aircraft tires, with an operating pressure of 0.7 MPa.
Data Acquisition
A dedicated high-speed data acquisition card is used for collecting test point data. The density of test points reaches 3–4 points per meter, significantly enhancing data accuracy.
Printing System
Equipped with an onboard printer capable of real-time printing. The printer is connected to the testing computer via a data cable and utilizes thermal printing technology.
