IRD Single Load Cell WIM (Weigh-In-Motion) Scale

The IRD Single Load Cell WIM weigh pads utilize a self contained weighing unit, with the weighing element consisting of a single load cell. The scale mechanism incorporates patented load transfer torque tubes which effectively transfer all loading on the weighing surface to the load cell, which is mounted centrally in the scale. The system consists of two (2) steel frames (per lane) which are installed into existing or new asphalt or concrete pavement, and weigh pads which are bolted to the installation frame.

The IRD Single Load Cell WIM scales are used for medium to high speed WIM and/or vehicle classification applications. The Single Load Cell WIM technology offers high accuracy and reliability for all data collection and enforcement pre-screening applications.
