Falling Weight Deflectometer (FWD) is one of the most advanced non-destructive testing equipment of road surface strength in the world. It has become a hot topic in the field of road in the world to measure dynamic deflection of road surface and calculate the rebound modulus of road surface.
As it has become a hot topic in the field of road in the world to measure dynamic deflection of road surface and calculate the rebound modulus of road surface, FWD(falling weight deflectometer) become a popular inspection machine for testing the deflection of pavement to ensure the pavement quality;
1. Easy to operate, and fully-automatic
2. “One-Key Operation” The whole testing task can be completed by one single person with pressing just one key on laptop.
3. Fast measurement, ≤20s/point, and can be reduced to ≤10s/point if fast measurement software applied.
4. Multi-functional and Professional
5. Strong and durable trailer base plate.
6. Equipped with laptop for wireless data transmission
7. GPS location and temperature measurement
8. Auto capture of deflection value and load value.
9. Continuous outdoor working.
10. Storage Battery Charging: charging by electric generator on the tractor
11. Double Locking System: Hydraulic/ Mechanical
12. Emergency System: Lift the load plate when system breaks down.
13. Operation Options: Manual/ Automatic
14. Working status of load plate can be monitored on the screen.
15. Inertia Braking
16. Synchronized turn/break/back light and head warning light with the tractor
