LG6225E 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.
LG6225E 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.
Imported engine 6BTAA5.9-C
The original imported engine 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.
Pilot System
The pilot pump is independent of main pump and supply oil to the pilot system which guarantee the stable and independent pilot control and facilitate the maintenance.
Monitor
The multi-purpose true color monitor allows the real-time monitoring and display of machine state, engine speed, coolant temperature, oil pressure and fuel level etc.
Power Control Mode
3 power modes of heavy-duty power mode (H mode), saving power mode (S mode) and light-duty power mode (L mode) can switch at will to reduce the system power loss. The combination of 3 modes can reduce the fuel consumption and better meet the different working conditions.
Fault Auto Warning
It allows the fault self-diagnosis auto warning display and fault message save up to 99,000 pieces approximately to facilitate the fault call and inquiry during the maintenance of equipment. There are 3 levels of warning display according to the fault severity.
Engine Overheating Auto Protection
The overheating protection will be active if the coolant temperature exceeds 102ºC. Then the engine will not stall while the system will reduce the engine speed. However, if the coolant temperature is too high, the operator should shut down the machine as required and find out the fault causes.
Low Oil Pressure Protection
When oil pressure below the standard value, the oil pressure switch will be closed, the text warning will display for 3 s and then the engine will slow down to low idle speed. In such a case, the operator should shut down the machine as required.
Maintenance Auto Remind
The monitor will periodically remind the operator of changing the engine oil, grease and filter element at the set interval to support the routine service.
Main frame
The reasonable layout of robust main frame optimizes the utilization of steels.
Undercarriage
The X-shaped undercarriagewith heavy-duty box structure is subjected to the repeated finite element analytical calculation and enhance the overall rigidity, strength and torsional resistance.Undercarriage is welded from the low alloy structural steel plates with overall process quality control. The critical welds are fully subjected to fault detection and stress test to ensure the product quality.
Track
There are ribs and crawler cradle in the middle of the track links. Using m-type seals to ensure the lubricating effect of the pin and pin suites.Extending the track working life effectively.
Travel Device
The drive unit employs the imported motors of high quality and the drive wheel adopts high frequency heating overall hardening process to enable the excellent wear resistance of the external gear rim.
