Description of Hydraulic Excavator
1. Adopts electric-hydraulic technology;
2. Lower operation cost: only 50-70% of that for excavator powered by diesel engine.
3. A streamlined appearance;
4. Perfect performance, powerful digging force,
5. High productivity and loading efficiency;
6. More availability and an extended operation life are available for this kind of engineering equipment;
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. Improved reliability with hose and seal
7. Case shape structure, attachment designed by CAD
8. Automatically injecting the fuel (Optional)
Applications of Hydraulic Excavator
1. The earth-moving excavator is employed to complete 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 different mines such as non-ferrous metal mine, building material mine, and other stripping &loading operation in water power plant.
