Tyres are an expensive part of equipment used in quarries and the longer they last the better as Patrick Smith reports
There is a perception that, compared to mining, quarrying is the soft side of the mineral resource industries.
Yet a quarry’s geology can be just as aggressive and demanding as winning Canadian Kimberlite, Chilean copper or Australian anthracite.
And, when it comes to load and haul, a quarry is just as likely to employ big loaders such as Caterpillar 990s and 992s; Komatsu WA 800s and WA 900s or, in some special cases, giants such as Caterpillar 994s; Komatsu 1200s and Le Tourneau L-1350s as it is to run more modestly-sized machines.
Where wheeled plant is used, the efficiency of the entire operation will rest on the tyres without which the earthmovers are, quite literally, grounded, says Erlau, the company that says it invented tyre protection chains (TPC) and which claims over 65% of the world market.
