The Shantui SG21-B6 is a next-generation 17-ton motor grader engineered to deliver precision leveling, ditching, and bank sloping with class-leading tractive efficiency. Driven by a high-torque 160 kW Cummins engine, it boasts an impressive maximum forward tractive force of 93 kN to plow smoothly through tough soils and dense materials. Equipped with a heavy-duty, fully enclosed slewing ring working device and an advanced A-pillar-less cab that expands visibility to a panoramic 320 degrees, the SG21-B6 ensures supreme grading accuracy, superior durability, and low-fatigue operations.Description
Shantui SG21-B6 Motor Grader – High-Efficiency Precision Leveling Power
The Shantui SG21-B6 is a next-generation, high-performance motor grader designed to handle heavy-duty leveling, ditching, slope scraping, trenching, and land-stripping operations. Integrating a premium mainstream engine with an elite drive system, this robust road grader generates some of the highest tractive force in the industry. It combines structural longevity with supreme blade accuracy, making it an indispensable asset for large-scale highway construction, mining haul road maintenance, airport development, and municipal engineering.
Key Features & Mechanical Advantages
- Industry-Leading Tractive Efficiency: Driven by the heavy-duty, turbocharged Cummins 6CTAA8.3-C215 engine outputting a powerful 160 kW. Meticulously synced with an optimized drive system, it maximizes torque to deliver a massive maximum forward traction of 93 kN for smooth grading under heavy material loads.
- Heavy-Duty Slewing Bearing Assembly: Equipped with an advanced, fully enclosed slewing ring working device and specialized high-strength cutting edges engineered directly by Shantui. This ensures flexible blade rotation, precise positioning, superior wear resistance, and high structural resilience against sudden job site impacts.
- Advanced 320° Wide-View Cab: The modern operator cabin features an innovative structural layout that eliminates the traditional A-pillar, opening up a commanding 320-degree panoramic field of vision. Outfitted with an adjustable mechanical suspension seat and low-effort electronic control handles, it drastically minimizes operator fatigue during extended grading shifts.
- Centralized Ground-Level Maintenance: Engineered for minimal downtime, the SG21-B6 features externally accessible lubrication ports for quick ground lubrication. Additionally, it integrates a centralized pressure testing system and externally arranged oil fillers, making routine diagnostics and fluid top-offs incredibly fast and safe.
- All-Condition Versatility: Designed with a multi-purpose architecture. The grader offers the structural flexibility to be equipped with a front bulldozer moldboard and a multi-tooth rear ripper, allowing it to transition seamlessly from precision finishing to hard soil breaking and stripping.
