movement of the whole grader by restraining the rotation of the axle. The
normal-closed wet multi-disc brake is used, when the hydraulic oil is
functioning, the brake is released; when the press of the hydraulic oil is
discharged, the brake is active through the action of the disc-like spring.

5.3 Comparison of Sany full Hydraulic motor grader and
other brand grader
Oil consumption:
——The oil consumption is a little lower than CAT grader and much
lower than KOMATSU, XCMG, TIANGONG grader and so on.
Operability:
——Sany grader possess the features as stepless speed change and
automatic gears shifting so the difficulty and strength of driving is
much lower than other brand graders.
Price:
——The price of Sany grader is much cheaper than CAT, KOMATSU
and other overseas brands’, but it is more expensive than domestic
brands’.
Reliability and working efficiency:
——The reliability of Sany grader is a little lower than CAT, KOMATSU
and other overseas brands’, but it is higher than domestic brands’;
——The Max. speed of Sany grader is slower than CAT and
KOMATSU’s but the reverse speed is higher than other brands’.

51/52
After-sales service:
——The after-sales service of Sany is better than other
brands’.
Hardware configuration:
——The engine, hydraulic pump and motor of Sany are all
world-class products. The configuration is not lower than CAT,
KOMATSU and other overseas brands’ and much higher than
XCMG, TIANGONG and other domestic brands’.
Disadvantage analysis of Sany grader:
——The full hydraulic system of Sany grader needs closer
maintenance.
——The Max. speed is lower as 35km/h
——Using DEUTZ high quality engine, so the requirement for
fuel is high. Using bad fuel will damage the engine.
