Key Features and Applications
Cummins Powertrain and Heavy-Duty Drivetrain
The GR2605 is powered by a turbocharged Cummins QSL8.9 diesel engine delivering 194 kW at 2,200 rpm. Matched with a multi-speed power shift transmission, the machine provides 6 forward speeds (up to 47 km/h) and 3 reverse speeds (up to 26 km/h), generating a traction force of ≥ 99 kN for heavy subgrade spreading, deep blade cuts, and rapid road transit.
Load-Sensitive Plunger Pump Hydraulics
The hydraulic architecture employs a variable displacement plunger pump and a load-sensitive valve system. By automatically distributing oil flow and working pressure according to the load demands of each actuator, the system enables smooth multi-cylinder composite operations, high responsiveness, and precise moldboard control during fine grading and bank slope trimming.
Circle Drive with Overload Protection
Engineered for severe earthmoving and open-pit haul road maintenance, the working device incorporates a heavy-duty slewing bearing and an overload-protected circle drive. When the moldboard strikes embedded boulders or encounters extreme resistance, the overload mechanism slips to absorb shock loads and protect hydraulic cylinders and drive gears from structural stress.
Wet Brake Axle and Travel Stability
The grader utilizes a reinforced drive axle fitted with wet service brakes, providing stable braking torque and thermal dissipation during continuous duty on sloped grades and mine haul roads. Articulated frame steering paired with front-wheel steering angles up to ±48° provides dependable directional stability and a turning radius of 7.9 m.
Broad Infrastructure and Heavy-Duty Applications
Built for high-load working conditions, the machine performs large-scale subgrade leveling, base course spreading, side ditch excavation, bank profiling, and snow removal across highway projects, airfields, mining access roads, and water conservancy earthworks.
