Sandvik Integrated Weighing System
By Mario Cywinski
Sandvik Integrated Weighing System (IWS) offers real-time payload data for load and haul equipment operators.
“Utilizing the full capacity of the truck, every cycle, has an enormous effect on total efficiency of the mine operations. Without the IWS, even a small drop in payload can result in a significant loss of shift production,” said Wayne Scrivens, VP Product Line Load and Haul, Sandvik Mining and Rock Technology. “From the equipment technical point of view, what makes the Sandvik IWS special is that the system is truly integrated into the equipment control system: no need for adding on any wires, sensors or other components; IWS is an integral part of the intelligence.”
IWS is a tool for monitoring efficiency, planning operations and improving fleet performance. IWS also allows truck operators to monitor the truck payload in real time. During loading, truck operator can see on the system screen the exact weight of the rock material in the box. A the same time, loader operator is guided with ‘traffic lights’ on top of the truck, indicating if free capacity is left, or if optimal load has been reached. This helps to achieve a full truckload every cycle, avoiding under or over load.
IWS also helps to ensure the box is empty, minimizing carry-back. Log files created by IWS can be transferred through My Sandvik Digital Services Knowledge Box for further analyses, or extracted into a USB stick.
IWS is available for Sandvik TH430, Sandvik TH545i, Sandvik TH551i, and Sandvik TH663i. Retrofitting to other models is possible.
