Komatsu introduces GD955-7 motor grader in USA
Komatsu has introduced the new GD955-7 motor grader to the North American market. An important addition to Komatsu’s motor grader line-up, the GD955-7 is said to offer operators the control and precision needed to build and maintain haul roads for truck fleets of 100 tons and up.
Komatsu says its powerful new motor grader stands out with its ample horsepower and powerful blade downforce pressure for efficient grading performance. With faster working travel speeds compared to the previous model, Komatsu engineered the GD955-7 to increase grading efficiency while helping reduce maintenance requirements and total cost of ownership. Quick specs are as follows: 426hp (313kW) at 1,900rpm; operating weight – 47,320kg (104,323lbs); moldboard – 5.5m (18ft) standard, 6.1m (20ft) moldboard optional.
Despite its large size, the GD955-7 promises 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 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.
