Chinese road construction shantui heavy motor graders SG21-3
SG21-3 Motor Graders
SG21-3 motor graders adopts the external ring gear type working device to achieve higher transmitted torque, larger blade cutting angle, and better material control capability and features the maximum traction force among the domestic like machines. This machine is applicable for large-area leveling, ditching, slope scraping, bulldozing, ripping, land clearing, and snow removing and is an ideally essential machine for large building constructions, water conservancy projects, and farm improvements.

Technical characteristics
1. Power systemDongfeng Cummins E E Q S B 5. 9 - C 1 8 0 or on the board S C 8 D K 1 9 0 G 3, Weichai WP6G190E330 turbocharged air-cooled high-pressure common high-pressure common rail engine, the country Ⅲ emissions.Its compact structure, stable performance, energy efficient. Torque reserves, to ensure that the machine in the harsh conditions of stable output power to meet your operating needs, is the engineering machinery industry, one of the main matching matching power.2. Transmission system The use of German mining (ZF) technology to produce electro-hydraulic control power shift transmission, with the first 6 after 3 stalls, according to operating conditions to choose the best gear, walking and operation with the best match. Three-section integral drive axle, built-in imported no-spin automatic slip differential, smooth and reliable transmission. balance box, up and down 15 ° angle swing, heavy roller chain drive, so that the machine has a better terrain adaptability. Can meet the normal road conditions in the normal construction operations, power output stable, strong driving force.
