○ Three phase-asynchronous electromotor, the only technology in China for hydraulic material handler powered by electricity, it is of benefit to environment protecting, power saving, easy service & maintenance, and low operating cost.
○ New dual electric brush and collector ring bring longer lifetime.
○ Control of constant power of single pump, limited power of three pumps for reasonable distribution of electromotor power
○ Starting with zero displacement so as to reduce the moment of resistance at starting
○ T echnique with pressure cut to protect hydraulic system and reduce the system heat
○ Secondary overloading for swing and normal closed brake for swing and travel ensure smoothly brake
○ Integrated oil& water cooler with compact conformation
○ The working attachment realized automatic level crowding with bucket to increase the bucket filling factor
○ Attachment designed by CAD, case shape and casting-welding structure realizing the high strength
○ Automatic central lubrication two pumps of system by control of micro-electronics to save daily lubrication
○ Better reliability with Parker hose &seals and Busak+Shamban cylinder seals
○ The Technique with disassembled undercarriage which is advanced to transport the machine quickly
○ Nitrogen dash control is the exclusive technology in domestic with a long cushion stroke and excellent shockabsorbing capacity
○ Cab with fixed elevation and integrated is provided with large tri-dimensional ventilation, fresh air circulation, large capacity air condition without fluorine
○ The operator’s cab with the wide vision field and the streamlined appearance, matching the decoration and function with human nature, and offering the working environment in a car.

The hydraulic excavator CED1000-7, 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 gradeⅠ~ 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 CED1000-7 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.
