BHP High Speed Train In-Motion Weighbridge Systems

The BHP high speed train weighbridges at Port Hedland and Newman (Western Australia) weigh 40,000 tonne trains on the move at speeds up to 80 kph. The BHP project brief included handling thousands of trains each year (equals millions of wheel crossings) without any Operator input, withstand extreme environmental conditions (cyclones, frequent lightning strikes, ambient temperatures up to 50 degC) and be available for 99.9%. The system also needed to comply with international legal trade accuracy requirements (0.5%). Meridian Engineers is one of the few companies in the world with the skills and technology to have achieved these results for BHP.
