Reducing Co2 emissions - With tough economic times looming and a strong awareness of human impacts on the environment, it is critical to cut costs and minimise environmental impacts.
Jeff Vickers discusses how Loadrite loader and excavator weighing systems can help to optimise truck loading. In 2006, Actronic Technologies started a project with the University of Auckland in New Zealand to reduce the environmental impacts of its Loadrite onboard weighing systems.
As quarries often install weighing systems to improve productivity, a sub-project was set up to compare the environmental impacts of the products themselves to the savings achieved by using them.
For a New Zealand quarry that uses Loadrite weighing systems to optimise road truck loading, it was estimated that 700,000 MJ of non-renewable energy consumption and 52 tonnes of CO2-equivalent greenhouse gas emissions were avoided for each loader that had a weighing system installed.
The potential impacts caused by manufacturing, distributing, using and disposing of that same weighing system were 144 and 154 times smaller respectively. While the improvement achieved will vary from quarry to quarry, such a large difference should not come as much of a surprise - an onboard weighing system uses much less energy than a wheel loader, yet it can significantly improve the operating efficiency of that wheel loader.
While the environmental impacts of the weighing system itself have been assessed quite accurately, much more data is needed on productivity improvement. If you are interested in how a Loadrite weighing system could improve the productivity of your quarry, there is an opportunity to participate in this study at the end of this article
