Product Description:

Construction Machinery CDM6085 features:

CDM6085 is equipped with a lownoise, low emission, small size, and strong power YANMAR engine. It is also equipped with a pump load independent flow distribution control system (LUDV) unrelated to the load pressure. The machine has many characteristics,such as energy saving, full-featured , good stability , high productivity, spacious and comfortable cab etc.
CDM6085 is widely used formunicipal engineering, garden project, irrigation and water conservancy constructionetc.

Yanmar TNV series engine
The original Yanmar four-cylinder, four-stroke, water-cooled, direct injection engine. It's powerful and fuel-efficient. Using the unique CAE technology of Yanmar, large muffler, and a new type cooling fan, effectively reducing the noise and vibration of the machine. And the engine conforming to Euro ⅢA 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 poor air quality working conditions and prolong the maintenance interval of the air filter. The oil-water separator and t high- precision 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.. This will enhance the service efficiency, relieve the customers of worry about the service and ensure the attendance rate of excavator.
Control Mode
New LUDV system is able to fine control the actions of each group of spool of multiple unit valve, and to distribute engine power as the largest proportion according to the system needs, so as to realize the best match under the variety of work conditions or working load, and resulting in the largest operation efficiency, as well as improve the operational stability and reliability of the excavator.
Fine control of the rotation speed (In the motion starts).
Flow and pressure control at the same time.
Effective control of the rotation speed (When associated with other motions).
Excellent acceleration and deceleration performance.
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. Parts are arranged closely to shorten the connecting lines and consequently reduce the line friction and pressure drop.
The large LCD display provides a convenient visual user interface. Operation parameters of the machine, such as engine speed, coolant temperature, engine oil pressure, fuel level, real-time and historical faults, may be displayed in the liquid crystal monitor.
Fault Auto Warning
Prompting the machine failure and automatic alarm through sound, light, and text.
Main frame
The reasonable layout of robust main frame optimizes the utilization of steels. 
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.
