China Lonking 22ton / 1.1m3 Hydraulic Excavator

CDM6240with 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.
CDM6240 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.
