The 135HP Road Motor Grader is a specialized equipment designed for road construction, maintenance, and land leveling, combining a 100 kW power output with precise grading performance. Its 3300mm-wide grading blade—made of wear-resistant steel—and 6-forward/3-reverse gearbox adapt to various road conditions, from soft soil roadbeds to hard asphalt surfaces. The machine incorporates a laser-assisted automatic leveling system that maintains a grading accuracy of ±3mm, ensuring uniform roadbed thickness and reducing the need for manual adjustments. This makes it an essential tool for highway construction, rural road maintenance, and airport runway preparation.
Power Train & Transmission: Equipped with a Cummins 6BT 5.9 turbocharged diesel engine, which delivers reliable power and torque for heavy grading tasks. The engine is paired with a ZF torque converter and a fully synchronized manual transmission (6 forward, 3 reverse gears), ensuring smooth power transmission and easy gear shifting—even under heavy loads. The torque converter’s lock-up function (activated at high speeds) improves fuel efficiency by 10% during long-distance grading operations (e.g., highway roadbed leveling).
Grading System & Precision: The grading system features a pendulum-arm linkage mechanism that allows the blade to adjust freely to uneven terrain, ensuring consistent contact with the ground. Two double-acting hydraulic cylinders control the blade’s angle (0° to 30°) and height, enabling precise slope trimming (from 0% to 40% grade). The optional laser leveling system—compatible with external laser transmitters—automatically adjusts the blade height based on pre-set grade data, achieving a grading accuracy of ±3mm, which meets the strict requirements of highway and airport runway construction.
Roadbed leveling and slope trimming in highway and expressway construction, ensuring uniform roadbed thickness (15-30cm) for asphalt or concrete paving
Asphalt pavement pre-paving preparation, including fine grading of the base layer to ensure smooth asphalt application
Rural road maintenance, such as filling potholes, leveling uneven surfaces, and trimming road shoulders to improve driving safety
Airport runway and taxiway maintenance, including precision leveling of the runway surface to meet aviation safety standards
Snow removal operations in cold regions, using the grading blade to push snow from road surfaces and shoulders
Q: What is the hydraulic system pressure, and how does it affect the blade’s operation?
A: The hydraulic system operates at a maximum pressure of 18 MPa, which provides sufficient force to lift heavy loads (e.g., compacted soil) and adjust the blade under heavy grading conditions. The high pressure ensures fast blade response (0.8 seconds from fully lowered to fully raised), reducing grading time and improving efficiency. Additionally, the system’s pressure relief valve prevents overloading, protecting hydraulic components from damage.
Q: Can it grade at specific angles, and how easy is it to adjust the slope during operation?
A: Yes, the blade angle can be adjusted from 0° (flat grading) to 30° (slope trimming) using the hydraulic control lever in the cab. The lever has a detent function that locks the blade at the desired angle, eliminating the need for the operator to hold the lever continuously. For precise slope control, the optional GPS slope monitoring system displays the current slope angle on the cab’s touchscreen, allowing the operator to make fine adjustments (±0.5% grade) quickly.
Q: What is the operating weight, and how does it balance stability and maneuverability during grading?
A: The operating weight is 14500 kg, which is optimized to balance stability and maneuverability. The weight is evenly distributed between the front and rear axles (front: 6000 kg, rear: 8500 kg), ensuring the machine remains stable during heavy grading without sinking into soft soil. The relatively light weight (compared to larger graders) enables flexible maneuvering in narrow areas, such as rural roads or construction site access roads, where larger equipment would struggle to operate.
