The 180HP Hydraulic Grader is a heavy-duty leveling machine engineered for precision ground treatment in large-scale construction projects, such as highway expansion and airport infrastructure. Equipped with a Cummins 6BTA 5.9 supercharged diesel engine (meeting Euro 4 emission standards) that delivers 132kW power, it achieves efficient soil and asphalt leveling with a 3965mm-wide, wear-resistant alloy steel blade and an operating weight of 16,000kg—a configuration that balances power and maneuverability. Its hydraulic control system, adopting Parker brand valves and hoses, ensures smooth operation across complex terrains like uneven mining sites or sloped farmlands, minimizing blade deviation during continuous work.
Powerful Propulsion: Integrates ZF technology torque converter with 6-forward/3-reverse gears, reaching 38.2km/h max speed; the torque converter’s lock-up function activates at medium speeds, reducing fuel consumption by 12% during long-distance transfers between work areas.
Precision Leveling: Dual-cylinder controlled blade with 360° rotation and 500mm cutting depth; the blade’s angle can be adjusted in 0.5° increments via the cab’s electronic control panel, meeting strict flatness requirements (≤3mm/m) for Class A highway subgrades.
Enhanced Stability: No-spin differential drive axle prevents wheel slippage on loose soil, while the box-type swing steering front axle reduces vibration transmission to the frame by 40%, protecting key components from wear.
Operator Comfort: Air-conditioned cab with six-point vibration reduction (lowering vibration amplitude to ≤0.8mm), a fully adjustable suspension seat, and a 7-inch touchscreen display that shows real-time engine temperature, hydraulic pressure, and blade position.
Ideal for highway construction (subgrade and surface leveling), airport runway precision treatment, large-area farmland renovation (converting scattered plots into standardized fields), and mining site preparation (leveling ore stacking areas). It is also suitable for asphalt surface trimming in urban road widening projects and industrial site grading (e.g., factory warehouse foundations), adapting to both dry and moderately humid working environments.
Q: What's the minimum turning radius?
A: 7.8m, enabling maneuverability in restricted workspaces like narrow mountain roads or construction zones surrounded by buildings.
Q: How to maintain the hydraulic system?
A: Check pressure (18MPa) monthly using the cab’s pressure gauge; replace oil filters every 200 operating hours; use ISO VG 46 hydraulic oil to avoid seal hardening in low-temperature (-5℃ to 40℃) conditions.
Q: What is the recommended replacement cycle for the leveling blade?
A: Under normal working conditions (leveling soil or asphalt), the blade can be used for 1,200-1,500 hours; replace it earlier if there are obvious cracks or edge wear exceeding 15mm.
