Komatsu unveils GD955-7: Largest motor grader for North America

Komatsu has introduced its largest motor grader, the GD955-7, targeted at the North American market. Weighing 104,323 pounds, a 50% increase in operating weight compared to its predecessor, the GD955-7 enhances blade downforce pressure and stability for tasks such as constructing and maintaining haul roads for truck fleets of 100 tons and more at quarry and mine sites, as well as other hard-packed road surfaces.

Joseph Sollitt, Komatsu director of mining support equipment, notes that the significant increases in operating weight, blade downforce pressure, and working travel speeds make this motor grader an efficient choice for mine sites. Redesigned front and rear frames contribute to reduced maintenance costs and increased durability by withstanding bending forces and torsional loads.

Powered by a 426-horsepower Komatsu engine, the GD955-7 stands out with its faster working travel speeds compared to its predecessor. It offers up to a 33% increase in productivity with the standard 18-foot moldboard and a 46% increase with the optional 20-foot moldboard. The direct-drive transmission and controllability of a torque converter drive transmission make it suitable for operators of all experience levels.

Despite its larger size, the GD955-7 can execute tight U-turns on a standard 100-ton class haul road without fully cutting the wheel. Its long wheelbase and large 27-degree articulation angle enable a tight turning radius, providing maneuverability for narrow haul road applications in confined spaces and around obstacles.

The cab features an air-suspension heated and ventilated seat to dampen mechanical vibrations. Designed with a hexangular shape, the cab, along with an integrated control console layout, improves visibility to the moldboard. Additionally, strategically placed mirrors and KomVision, offering a bird's-eye view on an in-cab monitor, further enhance visibility around the grader.
