The CNFORCE GR2805T Pro is a heavy-duty compact motor grader engineered for open-pit mining, heavy earthmoving, subgrade leveling, bank trimming, and terrain finishing. Powered by a 280 horsepower Cummins engine with high-strength steel structural sections, it integrates variable power control and load-sensing hydraulics to provide stable drawbar pull, precise moldboard control, and high energy efficiency under demanding site conditions.
Operating Weight: 21,000 kg
Engine Model: Cummins QSL8.9
Rated Engine Power: 280 HP (220 kW) @ 2,100 rpm
Moldboard Width: 4,270 mm
Brake System: Wet brake drive axle
Control Configuration: Electronic double-handle control
The grader is powered by a Cummins QSL8.9 diesel engine producing 280 horsepower (220 kW at 2,100 rpm). Featuring variable power control technology, the power plant adapts torque output dynamically to match shifting work loads, conserving fuel during transit and light spreading while providing strong drawbar force during heavy subgrade cuts.
The hydraulic architecture employs load-sensing technology that distributes flow and pressure in direct response to operational resistance. This reduces lever operating forces, delivers sensitive and predictable control response, and allows smooth compound cylinder movements during simultaneous blade lifting, side-shifting, and steering.
Equipped with an intelligent fan control system, the cooling fan dynamically adjusts rotational speed according to real-time temperature monitoring of engine coolant and hydraulic oil. This reduces parasitic power loss, cuts cooling system noise, and maintains stable thermal efficiency in tough operational environments.
The operator cab utilizes electronic double-handle control technology, integrating blade cylinder adjustments, steering, and machine travel controls into intuitive dual joysticks. This consolidated layout reduces operator physical effort, streamlines multi-function maneuvering, and improves work cycle efficiency.
The machine incorporates a heavy-duty wet-type brake drive axle, delivering dependable braking torque, continuous thermal dissipation, and long service life. The entire chassis and structural assemblies are fabricated from high-strength steel, engineered specifically for high-load operations including open-pit mining, heavy bulldozing, and haul road maintenance.
