TPMC-3
This trailer mounted Airport Runway Surface Friction Tester TPMC-3 is suitable for measuring the longitudinal force coefficient of asphalt pavement or cement concrete pavement. The test results can be used as the basis for completion acceptance or assessment of the pavement's anti-skid ability.
This trailer mounted Airport Runway Surface Friction Tester TPMC-3 is suitable for measuring the longitudinal force coefficient of asphalt pavement or cement concrete pavement. The test results can be used as the basis for completion acceptance or assessment of the pavement's anti-skid ability.
It consists of towing chassis, trailer frame, water tank, laptop and software, watering system, electrical control system, friction test wheel system with sensors, 12-15% slip rate guarantee system, alarm and safety warning system, etc.
FEATURE
◎It can provide two speeds of 65 km/h and 96 km/h for friction test.
◎It can perform dry and wet friction test and can test continuously.
◎An industrial touch screen laptop is used, which can realize the communication function with PLC and store more than 20,000 runway and taxiway test data.
◎Data sampling points ≥3 points/m to ensure data accuracy.
◎It comes with a water tank with a capacity of 600L. Under the condition of a water film thickness of 1mm, it can test ≥7000 meters at a full load. The test distance is adjustable, and the measurement distance can be longer in the non-sprinkling state.
◎The measuring tire is special tire that comply with ICAO and FAA regulations. The tire is replaceable and the working pressure is 0.207MPa.
◎The watering device is composed of water pump, valve and regulating system. The water flow rate per minute is set by the control valve to achieve different water film thicknesses.
◎The software can save, analyze and print the measured data, and can export the coefficient value of each meter of the runway surface and display the test results of the round-trip runway.

Braking system: The chassis is equipped with an autonomous braking device to avoid insufficient braking or failure of the tractor due to the huge speed inertia during the test (relevant certification materials must be provided), which is safe. The chassis should be equipped with an emergency brake device for unhooking to prevent the risk of rollover and high-speed collision caused by accidental uncoupling of the test equipment during testing.
