69 International Road Dynamics’ (IRD) durable IRD SAW III portable wheel load weigher is now available for dynamic weighing; its user-friendly software enables users to efficiently pre-select overloaded trucks.


Two IRD SAW scales are paired and connected to a PC via Bluetooth. When a vehicle drives over the scales at slow speed, the weighing result, wheel/axle weights and gross vehicle weight, is displayed on the screen. For weight enforcement with the highest accuracy the system can be switched to static operation mode. Computer-0based processing provides reporting, ticket printing and ticket archiving.

The system enables high vehicle throughput, especially when using two sets of IRD SAW scales, one set in dynamic mode for pre-selection and one in static mode for weight enforcement.

The low profile unit is designed to meet OIML R134 and it lightweight, rugged and corrosion resistant and suitable for twin tyre weighing.

  • Dynamic Message Signs : Don’t replace, refurbish and upgrade
    August 12, 2015
    Refurbishing old dynamic message signs can save money and increase technical capabilities as David Crawford discovers. Evidence is growing on both sides of the Atlantic of the scope for retrofitting old or technically out-of-date dynamic message signs (DMS) with new electronic equipment, to save on the costs of installing full-scale replacements. In the last four months of 2014, a number of US states progressed programmes that achieved savings of more than US$1.75 million (€1.56million).
