Product Details

Surface Trailer Friction Tester (STFT)

Automatic Frictional Coefficient Test Rig

Features:

1. Most of all supporting parts (over 90%) adapts imported or military aerospace products made of to ensure durability and stability.

2. Testing by Ministry of Transportation Highway Engineering Test Center: the correlation with Ministry of Transportation standard pavement and standard equipment reach to 0.99, the standard deviation of the standard ice road is 0.005.

3. With smooth rotation compensation mechanism to compensate test vehicle’s moving and uneven pavement in motion.

4. Transport wheels can be automatically tested and testing two state transitions and electric mechanical locking.

Performance and parameters:

1.Test speed: low speed of 20 km / h, high speed up to 100 km / h; drag speed 0-100 km / h;

2.Operation temperature: -25°C-+60°C humidity: 95% at 15°C;

3.Test wheel can measure the road surface friction coefficience on wheel tracks;

4.Friction test wheel(particularly smooth type): E1551;

5.Distance Test wheel: resolution+/-20mm;

6.Friction test accuracy: the average friction coefficient + / -0.01, in calculation, the numbers in the preservation of 5 m, 10 m, 15 m, 20 m is optional;

7.Distance measurement accuracy: + / -0.1% plus tire wear (can be changed to station no. according to the distance , and can be corrected);

8.The weight of test wheel when grouned (left and right wheels);

9.With stable compensation mechanism for broken pavement;

10.Towing hook height variation compensation shaft mechanism;

11.Broken pavement wheel load fast and stable mechanism;

12.Microcomputer automatic control tests on the rotation angle and lock the angle of rotation;

13.Wireless transmission of measurement and control;

14.Windows operation system;

15.Quick coupling connects with sprinkler;

16.Water film surveillance images is displayed in real time;

17.The car's own power supply provides power for the water supply system and measurement system, no external power supply unit;

18.Operating voltage: tractor supply, DC12V;
