Road Construction Machinery SHANTUI SG21A-3 210hp All Wheel Drive Motor Grader

SG21A-3 motor grader is an all-wheel drive motor grader developed on the basis of SG21-3, with three working modes (all-wheel drive, four-rear-wheel drive, and front-wheel crawling). Under the all-wheel drive mode, the traction force of the whole machine is increased by 30% to remarkably improve the working efficiency of the motor grader.

Engine model: 6CTAA8.3-C215

Technical Features

Cummins engine features reliable performances and high efficiency and energy-saving.

The 6-speed electronically controlled shift hydraulic transmission with Z-F technology features reasonable speed ratio distribution to ensure that the whole machine has three working gears at choice to ensure operating reliability and flexibility.

The box-type structure welded from integral plates features high strength.

The extern ring gear adopted features high transmitted torque, larger blade cutting angle, and better material handling capability and is especially useful while handling dry materials and clays. 

Featuring simple operations and high impact resistance against external forces, it’s applicable for the working conditions with high operating volume and severe operating environment.

The international advanced hydraulic brake control technologies and international renowned hydraulic units are adopted to ensure braking safety and reliability.

The full-hydraulic front wheel steering equipped features small turning radius and high mobility and flexibility.
