Construction Machinery CDM6225 features:

The CDM6225 - Our largest Excavator

Widely used for excavating, handling and finishing of earth & stones. With the optional breaking hammer, this excavator can be used for demolition and rock breaking.

Cummins 6BTAA5.9-C
The original Cummins high power Engine with guaranteed high reliability and durability.

Filtering System
Ensures the quality of fuel fed to the engine.

Specialist of Engine Management
10 Adjustable speeds.

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.

Color monitor allows the real-time monitoring and display of machine state, engine speed, coolant temperature, oil pressure and fuel level.

Power Control Mode
3 power modes of

(H mode) Heavy-duty power mode,

(S mode) Saving power mode,

(L mode) Light-duty power 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.

Low Oil Pressure Protection
When oil pressure is below the standard value, the oil pressure switch will be closed and the text warning will display for 3 seconds. 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.

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. This will extend the track life.

Cab Shock Absorption System
Reduced noise.

The windows allow free adjustment to open/close.

Standard Cab Equipment
The cab inside includes the cigar lighter, ash tray, cup holder, coat hook, cubbyhole and storage rack, which enhance the operation comfort.

A/C System

Deluxe Seat
Combat long time operation fatigue with a comfortable deluxe seat.

Boom and Arm
Made of high strength low alloy structural steels.

Pin Shaft
Thick chrome plating coat and high surface finish for longer lasting life.

The bucket body is made of low alloy and the external structure is made of high strength and wear-resistant steels. This excavator provides different bucket options to meet different working demands.
