Connecting Global Competence OUR COMPETENCE, YOUR INNOVATION. bauma CHINA, Shanghai, SNIEC, November 27–30, 2018 MINING TYRES Johni Francis at Titan told IM: “The reason we started with the larger ACT sizes was that the cost savings in the mines using the largest trucks were relatively the greatest. Changing wheels on larger trucks takes longer but with ACT downtime is still cut in half. The focus on safety in the larger sizes was also a factor. We have recently added the smaller sizes to bring the same benefits to smaller trucks, where there is a much larger truck population which can still benefit from the added safety and downtime savings.” Titan’s ACT customers tend to be the mines themselves, working with its global network of dealers. The most customers using ACT to date are in the US but there are also users in Canada, Australia, Chile, some African countries as well as Armenia, Greece and others. And it has been used for mines across numerous commodities from coal to metals. While there are a few competing technologies, each has differences and Titan has had a lot of good feedback so far due to the much lower changeover time, so that at some mines it has become standard practice. There was some initial conservatism as mines saw it as a complication to mix ACT wheels and conventional wheels. But after seeing the savings, most of the mines that have used ACT on a few trucks have then rolled it out for all their trucks of one size class. Freddy Hunt, General Manager, MS&R Equipment at Cedar Lake mine says of ACT: “We're turning those tyres anywhere from 4,000 to 7,000 hours depending on condition plus failures or operator error. Every time those tyres are changed they're saving us money. They've been such a saver to us in in downtime and tyre changes. They've been well worth the money we've spent and above and beyond that they're producing income for us now. We actually retain the wheels, the factory wheels, so we can put them back on to dispose of the equipment and I retain the quick change wheels. We actually let a set of trucks get away from us that we had sold. They got to North Carolina and I sent someone North Carolina to get my quick change wheels back.” More advanced large tyre repairs REGISTER NOW! www.bauma-china.com/register International Trade Fair for Construction Machinery, Building Material Machines, Mining Machines and Construction Vehicles. www.bauma-china.com Every year, mine sites around the world send thousands of ultra-class tyres with large injuriesfor scrap. Today, they don’t necessarily need to thanks to Kal Tire’s Ultra Repair™ technology that can provide like-new performance in even the most challenging environments, including Australia. Near the heart of the Hunter Valley coalfields in Muswellbrook, New South Wales, Kal Tire technicians repair injuries once thought impossible to fix on some of mining’s biggest tyres. This Kal Tire repair facility, and its counterpart in Kewdale, Perth, carry out standard repairs using conventional methods. But they are also leading practitioners of Ultra Repair - an innovation that uses a proprietary patch to replace damaged cables along with a unique installation technology to extend the life of mining tyres by potentially thousands of hours. Once developed, Ultra Repair quickly made its way to Australia and other countries where Kal Tire’s Mining Tire Group has a presence. Developing the game-changing technology, however, took an enormous investment in resources and time. Nearly 15 years ago, in the centre of the coal mine industry in BC, Canada, Kal Tire recognised the limitations of traditional earthmover tyre repairs, and began researching a process that could do more and solve one of a mine operator’s most expensive tyre problems. “We wanted to develop the materials and procedure to perform larger and stronger repairs,” says Kal Tire Mining Tire Group Vice President Tyre Lifetime Services, Darren Flint. “Today, we have the capability to repair not only large injuries, but also those in areas that were previously impossible to repair.” In 2014, Kal Tire launched Ultra Repair. “Where traditional patches for ultra-class tyres risked bulging, lasted just a short time and only suited smaller injuries and certain locations, like the tread, Ultra Repair expanded possibilities and ticked every box.
