Cab
It is made up of anti-corrosive steel plate, with streamline and full-width type, wide visul field, and elaborate structure. The interlayer safety glass is selected for the front windfield, with the full-sealed intenerated decorative element inside the cab. With heating and defrosting device and air conditioning system, it makes operators confortable, in addition, it has immproved the reliability and security of driving.

Power System
It characterized by oil saving, advanced design, and superior manufacture. It has made oil consumption 20% lower than that of domestic similar products.

Boom System The main boom is made up by hexagonal section boom sleeve, additionally, as the finite element analysis is adopted, the reasonable design and commpacted structure has been guaranteed. The boom is of rational joint, and it is of the advanced bearing capacity in China.

Hydraulic System
The cartridge inserted valves(USA VICKERS) are selected as electromagnetic valves of the controlling oil circuit, as they are designed in combination of the leading control valve, it is characterized by flexible action as well as stable and reliable performance,and it has also provided protections to numerous combined working conditions.

Slewing&Hoisting System
The planet gear deceleration device and normally closed brake is taken for the slewing mechanism, in addition, the rotary cushion valve for special purpose is equipped to ensure a stable slewing.and, it is of good inching capability. The stepless shifting is achieved in the main and auxiliary hoisting mechanisms,and, it is of high efficiency, large shifting ratio, and reliable working performance.

Chasis&Electric System
Optimal chassis design leads to smooth power shifting.
