TEAM power flow management technology allows engine power to be unlocked and locked by automatic control of the torque converter. This technology will make the speed and traction force more suitable for the actual working conditions of the grader, and achieve the target of "improvement of efficiency, energy saving and environmental protection".


Chenggong patented electro-hydraulic control shifting gearbox adopts 6 forward and 3 backward with stable shifting and precise control. It provides excellent working speed speed and powerful performance. Automatical control of the torque converter  unlock function takes the advantages of "rigid transmission" and "flexible transmission", achieving about 30% increase in operating speed and 20% reduction in fuel consumption than previous CG motor grader models, bringing greater economic benefits to final clients.


Patented wet brake rear axle adopts a special enhanced heavy-duty drive axle structure. The strength of the gears and shafts are greatly improved, and the load capacity is increased by more than 20% than previous models. "NO_SPIN" limited slip differential automaticaly control torque distribution , improving transmission efficiency. Intelligent temperature control for axle oil ensures that the drive axle works in the optimal temperature range, efficient and reliable.
