Higher requests are aked to the road anti-slip performance and detection means of city road and airport runway along with the development of the transportation cause. The Swing Type Portable Friction coefficient tester is developed by relevant scientific research unit and our factory. The instrument is stable and reliable, easy for calibrating, easy for operating, the test data is accurate, it can be compared with foreign product in the same field. This instrument could be used both in the room and field. It is the ideal anti-slip detecting device for high construction curing.
2. Principle
BM-III Swing Type Portable Friction coefficient tester is the dynamic swing impact instrument. It is developed and made in the principle of “the potential energy lose of swing is equal to work to overcome the pavement friction when the pendulum arm slipping on the pavement”.
3. Main technical parameters:
| Rocking torque | 615000g.mm |
| Pendulum mass | 1500g |
| Pendulum centroid distance | 410mm |
| Forward static pressure from rubber sheet to pavement | 2263g |
| Distance between rocking center to rubber sheet outer edge | 508mm |
| Net weighe | ≈14kg |
