Specifications:
- Machine type: Caterpillar 120 Motor Grader
- Blade size: 12-ft adjustable moldboard
- Blade angle: 30–90° tilt and side-shift
- Engine power: 145 HP diesel engine
- Operating weight: 15,070 kg
- Control: Joystick-assisted hydraulic system
- Tires: Dual rear-wheel traction with front steering
How it works:
1. The grader is aligned with the road edge for precise shoulder grading.
2. Operator adjusts blade angle and depth for the required surface slope.
3. Machine moves forward while the blade spreads and levels aggregate evenly.
4. Real-time hydraulic adjustments maintain consistency across terrain changes.
5. Final pass ensures fine leveling and compaction ready for sealing or asphalting.
Advantages:
- Smoother road transitions for safer driving
- Faster finishing on long stretches of road
- Reduces labor-intensive raking and leveling
- Hydraulic blade allows real-time depth control
- Ideal for both rural and urban paving projects
Disadvantages:
- Requires skilled operator for best accuracy
- Large machine unsuitable for narrow zones
- Higher fuel consumption during rough terrain grading
Productivity Impact:
Using this motor grader improves aggregate leveling speed by more than 65% compared to manual or hand-guided tools. It reduces the need for multiple surface corrections, shortening project duration by up to 40% in linear paving works.
Best used for:
- Road shoulder finishing and shaping
- Highway and expressway construction
- Pavement foundation grading
- Municipal road repairs and edge refinements
