As new mines transition into the critical production phase, graders often play an essential role, constructing and maintaining ramps and haul roads, and creating graded work areas for maximum safety and efficiency. Komatsu’s GD955-7, the most powerful grader in its class, is filling that need as it makes its Canadian debut at Argonaut Gold’s Magino mine, located 40 km northeast of Wawa, Ontario.
The GD955-7, which has proven itself in Australia’s rugged mining environment, is well matched for the harsh terrain and weather conditions that define Canadian mining. Critical to its adaptability is its blade downforce, which is the highest in its class. At 47 tonnes and 426 horsepower, the machine leads its class in both operating weight and power, and it also boasts the longest wheelbase for maximum stability, and the fastest operating speed to ensure maximum productivity. Overall, the machine can grade 33% more area per hour than the GD825A-2 with standard 5.5m blade.
