Our SS5 Shotcrete Sprayer was introduced in 2021 and part of the new design included on-vehicle technologies that helped improve the precision and efficiency of shotcrete application, as well as reduce the amount of chemical usage required in the shotcreting process.
The Maclean Quickscan system gives operators near real-time, digital measurement of shotcrete thickness on a user-friendly touch screen in the unit’s cab. As more and more of these equipment options get commissioned on SS5s in the field, we’ll be able to amass a data-driven picture of exactly how much concrete usage is reduced due to the quality of the spray thickness data that the technology offers up. But we are confident that the speed and the quality of Quickscan imaging will make a significant, positive difference to mining companies and the shotcrete operators who are integral to these companies’ ground support plans.
MacLean does have field data from the deployment of its Chemsave dosing system, which in a heavy volume spraying scenario can save mining companies up to 50% of their shotcreting accelerant chemical costs. This means the ROI on a MacLean shotcrete sprayer – the full repayment of the mining vehicle’s capital cost – could be achieved in less than a year’s operation.
Even in low volume spraying application scenarios, the machine repayment via chemical savings could still be realized in less than two years. The Chemsave system will not only benefit mining and tunneling operations financially but with proven data MacLean customers have seen heavy decreases in re-entry time, aiding with in-cycle shotcrete operations as well as an enhanced benefit on the quality of the shotcrete applied, no longer needing overdesigned mixes to compensate for potential strength degeneration over the long term.
The co-number one benefit of MacLean mining vehicle safety and productivity has always been the value proposition that we’ve marketed to the mining world, and now you can add TCO – Total Cost of Ownership – as an additional benefit of taking the ‘MacLean Way’ for innovation, manufacturing quality, and global product support.
