SHANTUI brand 210hp motor grader SG21A-3 all-wheel drive graders
Operating performance
It features the highest traction force among the domestic motor graders of like type and the highest operating efficiency among the domestic products of like type.
The external gear working device of proprietary technology features high drive torque and strong resistance against external force impact.
The blade of larger angular adjustment range (44°-91°) improves the material control capability and remarkably promotes the operating efficiency of motor grader, especially during the handling of dry material and clay.
With full-load scraping capability in 2nd forward gear, the motor grader can remarkably promote the production efficiency compared with domestic products of like type.
With high resistance against external force impact, the link type swing frame is applicable for the working conditions with high operating volume and severe operating environment.
Power System
It's powered by Dongfeng Cummins 6CTAA5.9-C215 China-II compliant inline, 4-stroke, direct injection, water-cooled, and turbocharged and intercooled diesel engine, featuring compact structure, stable performances, and high efficiency and energy-saving.
The high torque reserve enables the machine to output stable power under severe working conditions and meet your working needs.
