CST has been monitoring and improving belt weighing performance for nearly 40 years and has a world class track record.  

One site where CST belt weighers have proven their worth is in Mackay (Queensland, Australia) where 26 CST belt weighers are in action.  It is a ship loading terminal capable of handling more than 55 million tonnes of coal for export every year.  CST weighers have been trusted to provide crucial accuracy and reliability on this site for more than 35 years!  This began when three PFS4-4’s units were installed in 1986 on Stacker Reclaimers.  

As years went by, the port bought more and more CST belt weighers because the equipment and the service support proved to be excellent.

The site now has several different models of CST belt weighers installed;

• Precision fully suspended (PFS4-4) with Accuracy 0.25%
• Precision fully suspended (PFS4-4) with Accuracy 0.5%
• Precision fully suspended (PFS4-4) with Accuracy 1%
• Precision fully suspended zero deflection (PFS4-6-0D) with Accuracy 0.25%
• Precision centrally suspended (PCX 2-1) with Accuracy 2%
• Precision centrally suspended (PCS2-2) with Accuracy 0.5%

Over the last 35 years the site has been supported by CST’s service base in nearby Mackay where experienced CST technicians provide 24/7 maintenance, breakdown and spares support.  Vicko Sren has been with CST for 16 years as a Belt Weigher Technician. He is on-site full-time, and is responsible for keeping all 26 belt weighers in good order.  Vicko is just one of CST’s well established team of technicians based in Mackay who represent more than 50 years’ service experience between them. CST technicians are themselves supported by head office engineers and a very productive R&D team making them the most trusted team in the industry.

Recent developments from the CST R&D department have produced a new belt weighing system with certified +/- 0.1% Accuracy.  This very high precision system has been installed and tested in Australia and in Peru.  It is unmatched anywhere in the world.  CST is constantly improving and pushing the boundaries of belt weigher performance, with a focus on complete customer satisfaction.

We would like to thank the Mackay Service branch for the vital support they have provided to our well over two hundred critical installations in Queensland.  CST provides comprehensive service support across Australia from multiple service offices and in many overseas markets.
