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.
