Komatsu has introduced its new GD955-7 motor grader to the North American market, offering operations more control and precision when building and maintaining haul roads for mining truck fleets.
“With significant increases in operating weight, blade downforce pressure and working travel speeds, this new size class motor grader will be a smart choice for increased efficiency on our customer’s mine sites,” Komatsu director of mining support equipment Joseph Sollitt said.
Engineered to help reduce planned and unplanned maintenance downtime, the GD955-7 executes tight U-turns on a standard 100-tonne class haul road without the need to fully cut the wheel or course correct.
“Despite its large size, the GD955-7 offers excellent manoeuvrability,” Komatsu said.
“The long wheelbase and large, 27-degree articulation angle allow a tight turning radius and provide manoeuvrability for narrow haul road applications in confined spaces and around obstacles.”
Komatsu engineered the GD955-7 to increase grading efficiency while helping reduce maintenance requirements and total cost of ownership.
“The newly adopted, long-life circle bearing allows for smooth and precise rotation of the moldboard while eliminating the need for circle play adjustments or replacing wear plates,” Komatsu said
“Coupled with a standard auto-lubrication system, the GD955-7 is engineered to help reduce planned and unplanned maintenance downtime while helping to extend life to overhaul.”
