Komatsu has introduced several new motor grader models, each designed to meet the evolving demands of the construction and mining industries. These machines combine advanced technology, powerful performance, and operator comfort to deliver exceptional results.
GD955-7: Power and Precision for Heavy-Duty Applications
The GD955-7 is Komatsu's most powerful grader, featuring a 426-horsepower engine and an operating weight of 47,320 kg (104,323 lbs). This model is specifically designed for heavy-duty applications, such as constructing and maintaining haul roads for truck fleets of 100 tons and up. Its high blade downforce pressure ensures efficient grading performance, while the extended wheelbase provides maximum stability. The GD955-7 also boasts faster working travel speeds compared to its predecessor, enhancing grading efficiency and reducing maintenance requirements.
GD655-7: Versatility and Fuel Efficiency
The GD655-7 is a versatile motor grader suitable for various applications. It is powered by a 218-horsepower engine and has an operating weight of 17,350 kg (38,250 lbs). This model features a unique dual-mode powershift transmission with a torque converter, allowing operators to select between eco mode for fuel efficiency and power mode for heavy-duty tasks. The GD655-7 also includes blade lift accumulators to protect the moldboard and drawbar from damage, and its high-flow hydraulics with on-demand CLSS valves enhance operator efficiency.
GD675-6: Precision and Comfort
The GD675-6 is designed for precision grading and operator comfort. It is equipped with a dual-mode transmission that helps reduce fuel consumption by up to 15%. The grader offers the longest wheelbase in its class, providing exceptional stability for fine grading tasks. Its operator-friendly features include an air-conditioned cabin and ergonomic controls, ensuring comfort during long working hours.
GD705-5: High Performance for Heavy-Duty Tasks
The GD705-5 is a high-performance motor grader designed for heavy-duty tasks. It boasts a 250-horsepower engine and a top forward speed of 42.5 km/h (26.4 mph). The grader's large moldboard width and maximum depth of cut make it suitable for large-scale construction projects. Its advanced transmission system ensures smooth operation, while the spacious cabin provides excellent visibility and comfort for the operator.
