Komatsu launches GD955-7 in North America


Komatsu has unveiled the GD955-7 grader as its latest offering for North American sites seeking precision and control for operators.  

The GD955-7, previously announced for the Australian market, is a powerful machine packed with horsepower, which Komatsu’s team designed from the blade up. The powerful blade delivers immense downforce for an efficient grading performance.  

“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,” director of mining support equipment at Komatsu Ltd Joseph Sollitt said. 

Komatsu engineered the GD955-7 to increase grading efficiency while helping reduce maintenance requirements and total cost of ownership.  

Despite its large size, the GD955-7 offers excellent maneuverability. It can execute tight U-turns on a standard 100-ton class haul road without the need to fully cut the wheel or course correct. The long wheelbase and large, 27-degree articulation angle allow a tight turning radius and provide maneuverability for narrow haul road applications in confined spaces and around obstacles. 

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. 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. 

The GD955-7 offers the following specifications: 

  • Horsepower: 426 HP @ 1,900 rpm (313 kW @ 1,900 rpm) 
  • Operating weight: 104,323 lbs. (47,320 kg) 
  • Moldboard: 18-foot (5.5 m) standard, 20-foot (6.1 m) moldboard optional
