Reliable belt weighing equipment has been long required by bulk handling industries, especially mining. Australian miners have maintained a strong interest new innovations in this field. Australia has had a strong dependence on mining for many years. Some of the largest mining companies in the world have grown up on the basis of Australia’s mineral wealth (BHP, RIO, Zinifex). Alongside the mining companies, a support industry which provides process control equipment, industrial computer systems and instrumentation has also emerged and has grown together with the miners providing important industrial control system equipment.

The shared knowledge and experience in the instrumentation community has led to a number of products originating from the needs of the mining industry, some produced by government-funded organisations such as the CSIRO, and others from private companies who developed innovative products based on this demand.
CST was founded in 1984 in response to a long-standing industry need for more accurate, reliable and durable in-motion weighing equipment than was currently available. A key element of CST’s success has been its focus on developing the technology to bring high accuracy weighing technology to critical, and high value material weighing applications. An early project was provision of a belt weigher on which bonus payments were based at a NSW coal mine. CST gained quick acceptance in diverse parts of Australia such as Dampier, Tom Price, Port Hedland, Hay Point, Blackwater and other remote mining areas. The mining industry was the initial market in which confidence and trust in CST products, service and expertise began. These customer relationships were the genesis for the ongoing approach of partnering relationships CST encourages for the life cycle of their products.
A key feature of our weighers is their robust design and durability. A typical example is our four idler four loadcell belt weigher, the PFS4-4, 8 of which were supplied 20 years ago to Baal Bone Coal Preparation Plant in NSW. These 8 weighers are still in service and are still being regularly serviced by CST technicians. The site has now upgraded the electronics sets to our latest model, so the equipment has seen only 2 generations of electronics in 20 years.
An enviable reputation has been acquired by CST over the last 25 years, based on providing rugged and reliable equipment, mostly requiring only routine maintenance. Many customers have formed long term relationships with CST, regularly purchasing CST equipment for each new expansion. CST’s electronics sets have always had many unique features, including a built in linearity check, and the ability to test and calibrate PLC I/O without having to load the weigh frame with weights.
CST has developed a culture of being belt weigher enthusiasts and we like to take on the technical challenges of belt weighing. We take pride in being Australian and world leaders in providing our excellent weighing products. The CST team includes many employees who have chosen to stay with CST for more than 10 years. This has been invaluable in assisting and maintaining our relationships with our customers, many of whom have been faithful customers for the life of our business.
We have sought and been rewarded in finding international agents who have a similar passion for researching and developing the technology of accurate weighing. A key criteria in sourcing overseas agents is their level of technical competence, willingness to invest in research and development, and strong commitment to providing solutions to our customers needs and problems. Both within our company, and with our customers and agents, we seek to encourage contributions and dialogue between our ‘thinking community’ that is focussed on eliminating the ‘unknowns’ in weighing accuracy. A pivotal part of this is our systematised ‘Opportunity for Improvement’ procedure. Problems and suggestions are open for monitoring, input and review on a daily basis by all staff.
With well over 1600 active installations, CST has become a major presence in the Australian and export markets , at times being the dominant manufacturer. Over 25 years, CST has maintained a solid, enduring presence in in-motion weighing. As well as continual product development, CST is investing heavily in building and training an extensive, readily available service and maintenance team to ensure the ongoing high performance our equipment is routinely capable of. There are many good reasons for using the manufacturer’s own, specialist trained team, with backup and resources to handle everything from routine maintenance to troubleshooting ‘mystery’ problems. Our accumulated industry experience means our service team can help any make of weigher perform to its best possible capacity.
Due to CST’s contributions in the field of high accuracy belt weighing, CST has become involved in committee work with various government standards institutes. CST took part in the Australian National Measurement Institutes’ development of NMIV7, the Uniform Test Procedure standard for trade approved belt weighers. We have also been invited to sit on committees in the USA facilitated by the US National Institute of Standards and Technology , working on modifying and improving the current Handbook 44. We are working to increase respect for and increase knowledge about belt weighing, with the aim to improve the standard of belt weighing world wide.
We are committed to being the best belt weigher company in the world by providing the most stable and most accurate products, by working closely with our customers to learn about the real day to day issues involved in material transfer on conveyors, and by providing the most committed, resourced support service to our customers.
