Motor Grader Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Common power range | 100–220 kW (140–200 hp class most used) |
| Blade length | 3.7–4.9 m |
| Blade height | 600–700 mm |
| Articulation | ±20–25° frame articulation |
| Front wheel lean | Yes, for ditch cutting and side slope |
| Drive | Tandem rear; all-wheel drive available |
| Ripper / scarifier | Rear ripper and mid scarifier for compacted surfaces |
| Fuel consumption | 12–22 L/h |
| Typical duty | Daily haul-road pass plus formation finishing |
What a Motor Grader Is Used For
- Mine haul-road shaping and maintenance
- Construction formation and subgrade finishing
- Ditch cutting and drainage
- Spreading gravel and wearing course
- Airstrip and camp-road finishing
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every shift | Inspect blade cutting edge and end bits; check circle-drive backlash; tyre pressures. |
| Daily | Grease circle, blade links and articulation; clean the blade of packed material. |
| 250 h | Engine oil and filters; inspect circle wear inserts. |
| 500 h | Circle-drive oil; fuel filters; tandem-drive oil level. |
| Annually | Replace circle wear inserts; inspect frame articulation pins. |
Frequently Asked Questions
How often should a mine haul road be graded?
As often as corrugations start to form, which on a busy laterite haul can be daily in the dry season and after every rain in the wet. A scheduled daily pass is cheaper than waiting for the road to fail. Watering plus grading plus compaction is the actual system; grading a dry, loose surface just moves dust.
Why does my grader leave a washboard surface?
Speed too high, blade too aggressive, or no moisture in the wearing course. Corrugations are a resonance between tyre bounce and a dry, poorly graded surface. Slow down, take a lighter cut, and add water. A grader cannot fix a road that has no wearing-course material left.
Do I need all-wheel drive?
Useful in sand, wet laterite and on steep formation work. On a firm, well-built haul road tandem drive is enough. Specify AWD if the same machine will also build new roads in the wet season.
