Description of Hydraulic Excavator
1. Combines electric-hydraulic technology;
2. Lower operation cost (only 50-70% of that for excavator powered by diesel engine);
3. Has a streamlined appearance;
4. Delivers high performance, powerful digging force, improved productivity and loading efficiency;
5. Provides more availability and longer operation life;

Main Features of Hydraulic Excavator
1. Air-cooled diesel engine with Germany Deutz technology
2. Control system by total power for double pumps & circuits
3. The confluence of double pump, raising the working efficiency
4. The frequent-open swing, the walking brake
5. Independent oil-cooling system
6. Better reliability with hose and seal
7. Case shape structure, attachment designed by CAD
8. Automatically injecting the fuel (Optional)
Applications of Hydraulic Excavator
1. As a kind of engineering equipment, the powerful earth-moving excavator is used increasingly in the task of digging of soil grade Ⅰ ~ Ⅳ , and loading of exploded rocks, such as road construction, municipal project, water power plant, handling of slag, etc.;
2. It is also suitable for the exploiting and loading in all classes of mine, water and electricity construction on the site with convenience electric power.
