TML Small FWD System FWD-Light®

Portable. Graph ground characteristics in real time

Measurement possible by one person

FWD-Light® evaluates the rigidness of the ground by allowing its weight to drop freely and measuring the impact load and ground displacement to obtain the modulus of subgrade reaction and modulus of deformation. It is compact, lightweight, and portable, and automation technology allows it to obtain results quickly. With its ability to obtain multiple points, it ensures and improves the quality of measurements.




  • No reaction force device for loading necessary
  • Control up to four external displacement sensors (optional)
  • Compact and lightweight, easy to handle — excellent portability
  • Manage a field as a single area, not by individual points
