Komatsu is excited to introduce the new GD955-7R motor grader to the Southern African market. The GD955-7R offers operators the control and precision needed to build and maintain haul roads for truck fleets of 100 tons and up and is an important addition to Komatsu’s motor grader lineup.
This powerful new machine 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 GD955-7R to increase grading efficiency while helping reduce maintenance requirements and total cost of ownership.
Quick facts:
- Horsepower: 426 HP @ 1,900 rpm (313 kW @ 1,900 rpm)
- Operating weight: 47,320 kg
- Moldboard: 5.5 m standard, 6.1 m moldboard optional
- 48% higher engine output for up to 19% higher working travel speeds
- Up to 21% reduction in total maintenance time with bearing type circle system and auto-lubrication
- Main component 16,000h overhaul
- Efficient combination with popular trucks from HD785 to 830E
Despite its large size, the GD955-7R 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 GD955-7R is engineered to help reduce planned and unplanned maintenance downtime while helping to extend life to overhaul.
The GD955-7R comes standard with Komatsu’s 360⁰ camera system, KomVision, which houses a 5-camera system to provide a view around the vehicle using the KomVision monitor, with an additional rearview monitor for reversing and ripping operation. This system increases visibility for operators so they can get a full view of activity around the grader. The monitor informs them if another vehicle approaches or is in their line of movement – a great safety feature for busy mine sites.
The machine was introduced to customers at a launch event on 22nd July 2024, and the first GD955-7R is on its way to a customer.
