Chinese Lonking 21 Ton / 1.1m3 Hydraulic Excavator
CDM6225 with strong, powerful and high quality engine and advanced negative flow control hydraulic system to achieve the best power matching and minimum costand guarantee the optimum working efficiency.
CDM6225 is widely used forexcavating, handling and finishing of earth or stones to meet the demand of construction sites, factory, municipal engineering and park objects. With the optional bucket, the material handling, surface finishing, ditch excavation and river course cleaning can be achieved, with the optional breaking hammer, the building demolition, road surface repair and rock breaking can be achieved. The structural members are subjected to the repeated analytical calculation to ensure the rigidity and strength which can cope with the rigorous working conditions.
Cummins 6BTAA5.9-C
The original Cummins high power, high torque and turbo-charging 6-cylinder direct injection engine guarantees the high reliability and durability. The charge air cooling system over the compressed air can enhance the oxygen content upon combustion markedly. The center fuel injection under high injection pressure allows the uniform atomizing of fuel, guarantees the normal combustion and reduces the exhaust gas emission.
Filtering System
The high efficiency dual element air filter ensures the quality of engine air intake. In addition, the air pre-filter can carry out the rough filtration over the air intake to enable the operation under the poor air quality working conditions and prolong the maintenance interval of the air filter. The oil-water separator and two-stage fuel filter will filtrate the fuel many times to ensure the quality of fuel fed to the engine.
Cooling System
The parallel radiator cooling makes cooling effect better and service easier.
Maintenance and Service
The easy maintenance of direct injection engine reduces the cost of maintenance. The global after service of engine enables the sharing of global resources. This will enhance the service efficiency, relieve the customers of worry about the service and ensure the attendance rate of excavator.
Specialist of Engine Management
The engine speed allows 10 adjustable gears through the throttle potentiometer and achieves the precise management over the engine speed through the control of engine throttle by the DC servo motor. The engine allows the auto idling/acceleration function to reduce the fuel consumption.It has a function of touch power enhancement, can handle the high resistance working condition with ease.
Control Mode
The dual pump two-circuit total power control system adopts the mature and reliable Europe and America technology to control the flow, the proportional solenoid valve regulates the two-stage pressure control of the main overflow valve.
