The hydraulic excavator CED460-5, which are based on design platform of the international cooperation and global purchasing of components, adopt the latest technology in the world to meet customer’s desire for best performance. Bonny machines have a streamlined appearance which are accepted by international customers, perfect performance, powerful digging force, high productivity and loading efficiency at low operation cost, more availability and long operation life. The powerful earth-moving excavators are applicable to 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.; The powerful mining excavators are suitable for different mines such as non-ferrous metal mine, building material mine, phosphate ore, strip mine and other stripping &loading operation in water power plant.

The hydraulic excavator CED460-5 has combined electric-hydraulic technology successfully, it is the exclusive technology of Bonny. The operation cost is only 50-70% of that for excavator powered by diesel engine. So it is very applicable to the task of the exploiting and loading in all classes of mine, water and electricity construction on the site with convenience electric power.
