Key Features and Applications
Energy-Saving Shangchai Powertrain
Driven by a Shangchai SC7H190 diesel engine producing 140 kW at 2,200 rpm, the GR1805 features a high-torque reserve coefficient and variable power control technology. The drivetrain operates along an energy-conserving transmission curve that reduces fuel consumption during transit and light spreading, while maintaining high low-speed torque for heavy subgrade cuts.
Load-Sensing Hydraulic System and Rotation Under Load
The hydraulic circuit incorporates load-sensing technology to minimize power loss and improve flow distribution across concurrent multi-function operations. Equipped with a heavy-duty transmission turbine box, heat-treated blade guide rails, and a high-wear-resistant rotary gear ring, the moldboard mechanism supports smooth circle rotation under load for continuous shaping in demanding soil conditions.
Reinforced Axle Architecture and Maneuverability
Reinforced front and rear drive axles provide high structural strength for demanding earthmoving duties, supporting a maximum tractive force of ≥ 79 kN and gradeability of ≥ 25%. Front-wheel steering paired with an articulated chassis design allows a compact minimum turning radius of 7.2 m, facilitating agile maneuvering along narrow rural roads and curved infrastructure routes.
Noise-Dampened Cab and Intuitive Operator Controls
The operator cab utilizes multi-level vibration damping across the engine, cabin mounts, and seating. It comes equipped with integrated heating and air conditioning, sound-absorbing hood insulation, a reversing camera, an interactive touchable display, and an ergonomic console layout to ensure operator comfort and visibility across extended shifts.
Service Accessibility and Centralized Maintenance
The machine is built with a rear-tilting hydraulic hood with accessible side doors, facilitating ground-level inspection of filters, oil checkpoints, and electrical circuits. Durable wear components and protected hydraulic lines minimize downtime and simplify scheduled maintenance routines.

Frequently Asked Questions
What engine powers the CNFORCE GR1805 motor grader?
The GR1805 is powered by a Shangchai SC7H190 diesel engine delivering a rated output of 140 kW at 2,200 rpm, integrated with variable power control technology for optimized fuel efficiency.
What are the moldboard dimensions and cutting capabilities of the GR1805?
The standard moldboard measures 3,965 mm in length and 610 mm in chord height. It achieves a maximum lifting height of 410 mm and a cutting depth of up to 715 mm.
How does the load-sensing hydraulic system benefit jobsite performance?
The load-sensing hydraulic system automatically matches system output to actual operating loads. This reduces energy losses, improves response during compound multi-valve operations, and enables smooth moldboard rotation even under working loads.
Is the GR1805 maneuverable enough for narrow or curved road construction?
Yes. By combining front-wheel steering angles up to ±48° with frame articulation, the machine achieves a minimum turning radius of 7.2 m, allowing it to navigate sharp turns and restricted roadbeds efficiently.
