Atlas Copco gave attendees a sneak peek at the world’s largest articulated underground mining truck, the Minetruck MT85, at MINExpo in Las Vegas, Sept. 24 to 26.
Ben Thompson, product manager at Atlas Copco’s underground rock excavation division, explained, “This truck is designed to fit the same drift dimensions of 50 to 60 metric ton class trucks with one essential difference: It will haul 85 metric tons [93 tons] which gives a tremendous productivity boost in terms of fewer trucks and more ton/kilometers per hour.”
Thompson emphasized that the Minetruck MT85 also is fast and highly maneuverable on ramps and inclines.
“This means that fewer cycles need to be made which, in turn, reduces the cost of transport in relation to the amount of material hauled. Not only that, the new MT85 truck now gives mining companies a more cost effective way to haul ore in the mine. It makes it more attractive to go for deeper ore bodies by ramp instead of sinking a shaft.”
The Minetruck MT85 has high capacity with a compact footprint. It is 11.1 ft. (3.4 m) wide and 11.5 ft. (3.5 m) high, easily fitting into 19.7 by 19.7 ft. (6 by 6 m) drifts. And despite its length (46 ft./14 m), it has an impressive turning radius of 40 degrees, which is largely due to its electro-hydraulic steering of the rear axle that gives maximum maneuverability, according to the manufacturer.
The Minetruck MT85 also offers a high degree of modularity and options. The dump box can be tipped at the side of the vehicle as well as at the rear. There also are two tailgate configurations — hinged at top or bottom, three engine power alternatives (535, 760 or 1,010 hp [399, 567 or 753 kW]) as well as four-wheel or six-wheel drive.
