1.A whole sealing and shock absorbing luxury cab is equipped with wide view, stereophony, air-conditioner and top grade damping seat, constituting a comfortable environment.
2.The pilot operation is cozy and labor saving.
3.The central swing axle serves for a high stability of the whole machine.
4.Both the large wheel base and the large weight of the machine contribute to the high stability of the complete machine operation.
5.The fully hydraulic flow amplification steering system is adopted for flexible steering.
6.The hydraulic system adopts dual-pump-converging technology which is energy conservative and highly efficient. 
7.The working device is optimized for high digging force and high working efficiency.
8.The central articulated frame has a short turning radius and flexible operation. The tracks of front and rare wheels are in conformity when steering with less energy consumption, providing protection to the transmission shaft and wheels.
9.The parking braking adopts gas chamber braking: When the brake pressure is below 0.4MP during driving, the parking braking will automatically start locking the front and rare transmission shafts, so as to improve the security of the whole machine. 
10.Working devices like relief racket and quick change can be equipped optionally.
