Each machine action is under the pilot control. The right lever controls the motion of boom and bucket while the left lever controls the arm motion and upper structure swing. The foot pilot valve is provided with the lever joystick to control the machine traveling or turning by the foot or lever. The traveling gear shift adopts the solenoid switch control.
System voltage:24 V
Battery:12 V，120 A×2
Benefits & Features
Construction Machinery CDM6235E features:
CDM6235E with strong, powerful and high quality engine and advanced negative flow control hydraulic system to achieve the best power matching and minimum cost and guarantee the optimum working efficiency.
CDM6235E is widely used for excavating, 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 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.
Functions This machine allows the functions of straight travel, boom/arm confluence, boom/arm holding, swing priority, swing anti-reversing and regeneration of arm cylinder. Each circuit without interference during composite action. Digging of arm and bucket as well as the lifting and swing of boom at the same time during operating, the operations of left and right motors are independent during traveling.
Auxiliary Hydraulic Valve The main valve is provided with a set of standby valves to facilitate the installation of other accessories such as the breaking hammer.
Filtering System The hydraulic circuit is equipped with the high quality hydraulic oil filter which can prolong the service life of the hydraulic elements.
Components Layout The special design of hydraulic system and components location can enhance the system efficiency of the machine. The hydraulic oil tank, main pump and main valve are arranged closely to shorten the connecting lines and consequently reduce the line friction and pressure drop. The radiator is arranged at the right side behind the cab to effectively reduce the noise, hot air and exhaust gas received by the operator.
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 102℃. 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.
