Having introduced the ST7 model in 2010, Atlas Copco reported that it is now the bestselling model in the entire Scooptram line. During field testing in the Lovisa mine in Sweden, the original ST7 was praised for improving overall load operations as well as the operator’s work environment. Recent customer reports mention longer service intervals, fewer spare parts due to improved wear, lower noise levels, improved lighting and more efficient emergency/alarm systems.
“But the biggest advantage is still probably the ST7’s fuel efficiency,” said Ed Tanner, business line manager—Underground Rock Excavation for Atlas Copco in the U.S. “One particular customer reported a fuel consumption of about 2.6 gallons per hour, about half that of their older LHDs. The secret is the on-board computer that calculates the optimum power needed at any time during operations, resulting in lower fuel consumption and reduced emissions.”
The Scooptram ST7 is equipped with a water-cooled 193-hp Cummins QSB6.7 EPA Tier 3 engine. It is a high performance loader with a 6.8 ton tramming capacity, articulated steering and oscillating rear axle. It has a comfortable, ISO FOPS/ROPS certified cab, a tramming height of 85 inches and width of 90 inches.
