GD955-7R
Overview
Introducing Komatsu's latest mining grader, the GD955-7. Weighing in at nearly 47 tonnes and 426 horsepower, this grader is designed to be a highly productive unit, achieved through its market leading blade down force and high engine horsepower enabling faster operating speed. The GD955 also boasts extended component lives compared to the previous model. The GD955-7 is built to thrive in the rugged conditions and its structural integrity is a testament to Komatsu's design philosophy.
The GD955 is well matched to larger haul trucks, making it a great addition to mining fleets. And it comes standard with Komatsu’s 360° camera system, KomVision, which houses a 5-camera system to provide a view around the vehicle using the KomVision monitor, with an additional rear-view monitor for reversing and ripping operation.
High productivity
GD955-7 can grade 33% more area per hour than GD825A-2 with standard 5.5 m blade. Extended blade width and 48% higher engine output for increased working speed enable more efficient operation which is required in mining operation. Optional 6.1 m blade provides more working width in easy operation and keeps working speed by using aggressive blade angle in heavy grading.
Blade stability
Thanks to 50% operating weight heavier than GD825A-2, GD955-7 can more easily grade hard packed road surface. In addition, expanded tread and increased weight on axles keep work stable in various condition. A long wheel base allows the operator to obtain an aggressive moldboard angle. This wide blade angle permits material to roll more freely along the blade, which reduces power requirements.
Easy to operate
Although GD955-7 has long wheel base geometry common to Komatsu graders, it can turn sharply with wide steering angle and articulate angle. GD955-7 can turn on 24 m width road without cutting of the wheel, and has wider working range thanks to extended blade width and wide articulate angle.
