Detailed 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.

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.

Idler Cushion
The idler cushion with high quality sealing elements effectively guarantee the high pressure sealing inside the cylinder block, the springs are subjected to the special heat treatment to allow the excellent fatigue resistance.

Cab Shock Absorption System
The cab shell is installed to the platform through the cushioning materials consisting of the silicon oil and rubber to relieve the vibration, reduce the noise and guarantee the operation comfort.

The glass is clung to the cab directly without frame to enlarge the visual field. The windows allow free adjustment to open/close the front and upper window and windshield,besides, the front glass can be set to the roof above the operator.

Front Wiper
The wiper located in front of cab pillar enlarges the operator's field of view, it allows the continuous and intermittent operation modes.

Safe and Comfortable Cab
The spacious and multi-function cab designed according to ergonomics enhances comfort for operator. The reasonable layout of control elements inside the cab allows easy operation.

Standard Cab Equipment
The cab inside includes the cigar lighter, ash tray, cup holder, storage rack, coat hook , escape hammer, and fire extinguisher.

A/C System
The high performance and healthy A/C allows the air circulate. Concise control panel and easy press key operation, multi-direction A/C air outlet allowing fast regulation of cab inside temperature and fast defrosting.

Deluxe Seat
The comfortable suspension type seat is provided with a hydraulic damper, the wide seatback allows the waist support and the curve profile enables comfortable riding, the double slide track multi-way multi-step regulation enables different operators to find the best posture, the wide pedal space allows the free body stretching and relieves the operator from the long time operation fatigue.

Safety Lock Joystick
The hydraulic safety lock joystick is located at the outside of center left armrest box in the cab. The machine control is active only when the joystick is in ON position, which can prevent the wrong operation in an effective way.

Control Lever
The reasonable design of control lever saves the operating effort by the lever principle, the ergonomic design enables the operator to maintain the natural wrist and arm posture. The moderate joystick stroke relieves the degree of fatigue and ensures the accurate control.

Switch Control Panel
The control panel on the left/right pilot box is in concise and esthetic layout and the operation of keystroke is easy.

Boom and Arm
To cope with high load during operation, the design & development team of LONKING adopts lots of up-to-date design ideas, preserves the higher safety factor, employs finite element analysis, calculation and optimum design to finish the development of boom and arm and selects the high strength low alloy structural steels for the boom and arm fabrication.

Pin Shaft
The pin shaft is the core element for the connection of the working equipment. LONKING chooses the professional pin shaft suppliers and subject the pin shafts to the strict fault detection to ensure the quality. The pin shaft of LONKING excavators has thick chrome plating coat and high surface finish. The special treatment enables the extremely high wear resistance and corrosion resistance.

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. Standard bucket with flat-floor which is praised by users is more suitable for the formation conditions. This excavator provides different bucket options to meet different working demands.

Easy Maintenance and Service
The design and layout of CDM6085 consider to providing convenience for maintenance personnel. Most maintenance locations can be accessed from the ground level to enable the fast and high efficiency maintenance. The maintenance points are clearly identified, easy to operate. The electrical elements are near the outside of machine to facilitate the maintenance.

Long Maintenance and Service Cycle
The maintenance and service cycle of CDM6085 has been prolonged to reduce the maintenance parts collection and enhance the availability.
