SHANTUI 17ton Chinese brand SG21A-3 articulated motor grader for sale
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
Working adaptability
● With 6 forward gears and 3 reverse gears, the electro-hydraulically controlled power shift transmission can select the optimal gear based on the working road condition to realize the best match between traveling and operation.
● The integral three-segment drive axle is built internally with imported no-spin automatic limited slip differential to guarantee stable and reliable drive.
● The balance box is capable of 15° angular swing in vertical direction and the heavy-duty roller chain drive guarantees better terrain adaptability of the machine. It can meet the normal operations under special road conditions, featuring stable power output and strong drive force
Driving/Riding Environment
● The high-grade full-sealed luxury cab with full visual field and the high-efficiency shock-absorbing seat maximize the operating comfort.
● The cab and the main frame are connected by shock absorber to ensure the operating safety and reliability
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
