Feature:
Cumins Engine
The original Cummins high power, high torque and turbo-charging 4-cylinder direct injection engine guarantees the high reliability and durability. The air-air inter
cooler 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 emission. And the engine conforming to Euro 3A emission standard is optional.
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 high dust concentration 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 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' worry 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
Adopt negative flow control system or dual-pump double-circuit constant power control system. Adopt boom holding system and swing cushion valve control.
Engine Overheating Auto Protection
The overheating protection will be active if the coolant temperature exceeds 102ºC. Then the engine will not flameout 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 3s and then the engine will slow down to low idle speed. In such a case
, the operator should shut down the machine as required to protect the machine.
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 undercarriage with 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 roll and pin bush.Extending the track working life effectively.
Track rollers
The reasonable arrangement of track rollers better distributes the stress applied to the track shoes.
Carrier rollers
Carrier rollers with reliable overall sealing property enables the long service life.
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.
Bucket
The bucket body is made of low alloy and high tenacity materials and the external structure is made of high strength and wear-resistant steels, which constitute the entire reinforced bucket.
This excavator provides different bucket options to meet different working demands.
Easy Maintenance and Service
The design and layout of CDM6150 has taken the providing convenience for maintenance person into consideration. Most maintenance locations can be accessed from the ground
level to enable the fast and high efficiency maintenance. 3 side doors can be opened during the routine inspection and maintenance and each service point is within the easy reach.
The maintenance points are clearly identified, easy to operate. The electrical elements are centralized in the electromechanical control box in the cab to facilitate the maintenance.
Long Maintenance and Service Cycle
The maintenance and service cycle of CDM6150 has been prolonged to reduce the maintenance parts collection and enhance the availability.
