UNDERGROUND DRILLING
Nokian Tyres Armor Gard 2 Mine tyre size for underground drills
Efficient tyres make underground mining safe and smooth - and Nokian Tyres ’ Armor Gard 2 Mine it says is now available in smaller size of 9.00-20 , specifically aimed at drill rigs working in harsh mining conditions .
Nokian Tyres Armor Gard 2 Mine it says offers excellent cut resistance , great handling and a long service-life . The tyre has up to now only been available in size 10.00-20 . Now the new size , 9.00-20 , makes its qualities available for even more vehicles .
Kimmo Kekki , a Global Product Manager at Nokian Heavy Tyres : “ Nokian Tyres Armor Gard 2 Minehas already proven its value among its customers . And we are excited to introduce this new size , as now more and more mining workers get to feel safe while working efficiently . It ’ s just an overall smoother experience with these tyres on your vehicle .”
Underground mining and underground drilling in particular set special demands on the tyres . Sharp rocks increase the risk of tyre damage . Slippery stones call for a great wet grip . The tight spaces make the environment hard to navigate , allowing only compact machines to move freely . And yet , even with extra high safety demands , Nokian Tyres says its Armor Gard 2 Mine ticks all the boxes . “ These are the tyres one can rely on even in the most challenging underground conditions ,” says Kekki .
Compared to the previous generation of Armor Gard tyres , Nokian Tyres Armor Gard 2 Mine is vertically 25 % stiffer . It also has 12 % more tread rubber . The tread is wider than before , which lowers the contact pressure and makes the tyre more hard-wearing .
The insert windows maximise tyre cooling and the durability of the carcass . And what is more , the New Nokian Tyres Armor Gard 2 Mine version has improvements to the tyre inner liner to maximise tube durability and improve the quality of the tyres . Lastly , the tyre itself is reshaped to be more rectangular than before , which increases its stability by up to 25 % compared to the previous model . “ Throw in the precise handling ”, Kekki says , “ and you can say these tyres are well equipped to tackle any threat underground mine sites hold .”
