Medium Speed Weigh-in-Motion Hybrid Bending Plate

Bending Plate Hybrid bending plate is low-profile and sits directly on load cells.
The system consists of a base frame that is fixed in the road and
Bending plates have strain gauges fitted in the plate itself. Two a top plate fitted with double ended sheer beam type load cells.
