The powerful new GD955-7 motor grader from Komatsu offers control and precision for building and maintaining haul roads for truck fleets of 100 tons and up. It features ample horsepower and powerful blade downforce pressure for efficient grading performance.
The GD955-7 has a faster working travel speed than the previous model, making it more efficient while also helping reduce maintenance requirements and total cost of ownership.
"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," said Joseph Sollitt, Director of Mining Support Equipment at Komatsu Ltd.
The new grader has an operating weight of 104,323 pounds (47,320 kg) and features an 18-foot moldboard as standard. A 20-foot moldboard is available.
Maneuverable for its size, the GD955-7 is able to execute tight U-turns on standard 100-ton class haul roads without the need to fully cut the wheel or course correct. A 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.
A newly adapted long-life circle bearing allows for smooth, precise rotation of the moldboard while eliminating the need for circle play adjustments or replacing wear plates. A standard auto-lubrication system helps reduce planned and unplanned maintenance downtime while helping extend life.
