KOMATSU GD530A-2C MOTOR GRADERS

Technical Description

The Komatsu GD530A-2C is a heavy-duty articulated motor grader powered by a Komatsu S6D102 turbocharged diesel engine delivering 143.5 horsepower at 2,500 rpm with six cylinders and 358.9 cubic inches of displacement. This machine features a 12.1-foot wide, 26-inch high moldboard designed for precision grading, leveling, and earthmoving operations. With an overall length of 27.7 feet, width over tires of 8 feet, and operating weight of 30,247.5 pounds, the GD530A-2C offers substantial stability and control on various terrains. The transmission incorporates six forward gears with full power shift and an integral torque converter, enabling maximum forward speeds of 25.5 mph and reverse speeds of 13.7 mph. The articulated frame design provides a 20-degree steering articulation angle for enhanced maneuverability in confined spaces. An 89.9-gallon fuel capacity ensures extended operational periods during long workdays. The grader rides on 13.00-24-10PR pneumatic tires and features sealed oil disc brakes acting on four tandem wheels for reliable stopping power. Standard equipment includes a deluxe enclosed ROPS/FOPS cab with low profile, full hydraulic steering with leaning front wheels, load-sensing closed-center hydraulic system, and comprehensive controls for blade lift, pitch, shift, rotation, and float operations. The 20-degree articulation angle combined with 1-foot ground clearance at both front and rear axles enables effective ditching, bank cutting, and slope creation capabilities essential for road construction and maintenance.
