Hydraulic parts: The swing reducer and the pilot control valve are use of internationally well-know brands.

Travel devices: based on the ltaly and China joint venture products, we can ensure the quality. By advanced processing means.

Connectors: World's top 500 eaton company's, the world's top pruducts, exceed DIN standard nonsuch, applicable to the various excavator in poor working conditions, anti-seismic, anti-loose, high reliability and long service life as a dream in the world.

Structure: Using domestic high-quality 16mn steel, welding technology on the international track, greatly increase the structuralstrength, thus ensuring the safety of traffic and construction. Blasting handling vehicle, an increase of paint adhesion, delayed the rusty parts, components increased life expectancy.
Radiators: Radiators're aluminum more fin heat sink, using vacuum brazing process, the promotion of spoiler, enhanced heat transfer coefficient, small hydraulic flow resistance, and can also easily manipulated even in the hot summer.
