200+ hp Motor Grader
The 200+ hp motor grader class comprises heavy-duty machines engineered for mine haul road maintenance, large-scale earthworks, and industrial site preparation. These graders deliver engine power from 158 to 755 horsepower and operating weights spanning 14,550 to 74,000 kg, with blade widths and moldboard capacities scaled to move substantial volumes of material in challenging conditions. This size class sits at the top of the motor grader ladder, above the 150–200 hp band, and represents the largest machines in contractor and industry fleets.

Especificaciones clave
| Especificación | Rango típico | Qué significa |
|---|---|---|
| Engine power | 158–755 hp | Power range supports applications from large civil earthworks through heavy mining haul road grading. |
| Operating weight | 32,077–163,142 lb (14,550–74,000 kg) | Mass provides blade penetration and traction in hard, uncompacted, or rocky material. |
| Blade width | 3.7–7.3 m typical | Wide moldboards cover haul roads and building pads in fewer passes. |
| Drawbar pull | High torque at low speed | Enables scarifier ripper engagement and grading through dense aggregate or subgrade. |
Cómo elegir
The 200+ hp motor grader is appropriate for mine haul road maintenance, large dam and levee construction, airport runway grading, and industrial site earthworks where blade width, mass, and drawbar pull are needed to cut, spread, and finish in fewer passes. Operators working on large-scale projects with hard or rocky subgrades, or maintaining multi-lane haul roads, will find the power and weight of this class necessary. For highway construction, municipal road work, or subdivision grading where machine size and fuel consumption are concerns, the 150–200 hp Motor Grader offers sufficient capacity with lower operating cost and easier transport. Projects requiring the largest available blade widths and maximum traction in mining or heavy industrial environments specify this top class.
Lo que maneja este tamaño
- Grading and maintaining haul roads at open-pit mines
- Final grade and drainage on airport runways and taxiways
- Large dam embankment shaping and compaction preparation
- Industrial park and logistics center site preparation
- Highway interchange earthworks and subgrade finishing
- Levee construction and flood-control earthworks
Seguridad y operación
- ROPS/FOPS certified cabs standard; operators work at elevation with limited visibility to the rear and blade ends
- Blade articulation, scarifier, and ripper controls require coordination training to prevent tip-over or equipment contact
- Wide turning radius and long wheelbase demand adequate operating clearance from walls, slopes, and other equipment
- High fuel capacity and pressurized hydraulic systems require spill containment and fire-suppression awareness on site
Transporte y logística
- Heavy-duty lowboy or multi-axle tilt trailers required; machines in this weight class often exceed legal road limits without permits
- Transport width with blade attached may require dismounting or special-width permits depending on jurisdiction
- Self-loading onto low-angle tilt trailers common; smaller models in the range may use standard heavy equipment trailers
Alimentación
- Diesel fuel; daily consumption varies widely with engine size, load factor, and duty cycle but can exceed 200–400 liters per shift on large models
- On-site bulk fuel storage typical for multi-machine mine or large civil projects; DEF (diesel exhaust fluid) required for Tier 4 Final engines
- Cold-weather operations may require block heaters or auxiliary warming systems for reliable starting
