落锤式弯沉仪

Falling Weight Deflectometers

Model No. FWD-0001 · Highway & Pavement Testing Equipment

Trailer-Mounted Falling Weight Deflectometer 7–120 kN

拖车式落锤式弯沉仪 7–120 kN

Highway agencies planning rehabilitation need layer moduli, not just a single deflection. This trailer FWD drops loads from 7 to 120 kN through a 300 mm segmented plate and records the bowl on 9 geophones to 1 µm resolution. A three-drop station takes about 30 s, with GPS and a distance encoder tagging each point.

Peak load range
7–120 kN
Load pulse duration
25–30 ms half-sine
Loading plate
300 mm diameter, segmented
Deflection sensors
9 geophones, up to 2,250 mm offset
Deflection range
0–2.0 mm
