Komatsu have introduced the new GD955-7 motor grader to the North American market, offering operators the control and precision needed to build and maintain haul roads for truck fleets of 100 tons and above.
An important addition to Komatsu’s motor grader line-up, the new machine stands out with its ample horsepower and powerful blade downforce pressure for efficient grading performance. With faster working travel speeds compared with the previous model, Komatsu have engineered the GD955-7 to increase grading efficiency while helping to reduce maintenance requirements and total cost of ownership.
Quick specs:
- Horsepower: 426hp (313kW) at 1,900 rev/min
- Operating weight: 104,323lbs (47,320kg)
- Moldboard: 18ft (5.5m) standard, 20ft (6.1m) optional.Despite its large size, the GD955-7 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° articulation angle allow a tight turning radius and provide manoeuvrability 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.
‘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 customers’ mine and quarry sites,’ said Joseph Sollitt, director of mining support equipment at Komatsu Ltd.
