Product Description

Product Description

Imported engine TNV series engine is equipped with a low noise, low emission, small size, and strong power imported engine. It is
also equipped with a new type of independent flow distribution hydraulic system (LUDV) unrelated to the load pressure. The machine owns characteristics of energy saving, full functional, good stability, high productivity, spacious and comfortable cabin etc.
It is widely used for municipal engineering, garden project, irrigation and water conservancy construction etc.
Imported engine four-cylinder, four-stroke, water-cooled, direct injection engine. It's powerful and fuel-efficient. Using the
unique CAE technology, large muffler, and a new type of cooling fan, effectively reduces the noise and vibration of the machine.
And optional with the engine conforming to Euro IIIA emission standard.
Cooling System
The parallel radiator cooling makes cooling effect better and maintenance easier.
Maintenance and Service
The easy maintenance of direct injection engine reduces the maintenance cost. This will relieve the customers of worrying about
the service and ensure the attendance rate of excavator.
Control Mode
New LUDV power balanced system and flow distribution system irrespective of loading pressure is able to fine control the actions
of each group of valve core of multiple 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 excavator operational stability and reliability.
Functions
Fine control of the rotation speed (In the motion of starts & operation).
Flow and pressure control at the same time.
Effective control of the rotation speed (When associated with other motions).
Excellent acceleration and deceleration performance.
Arm regeneration circuit, to promote excavating speed.
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.
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 pipes and consequently reduce the pipes friction and pressure.
Monitor
The large LCD display provides a convenient visual operation interface, the machine working condition and operation parameters
such as engine rotating speed, coolant temperature, engine oil pressure, fuel level, real-time and historical faults are displayed
intuitively.
Fault Auto Warning
Warning the machine failure through sound, light, and text, and automatic alarm.
Main frame
The reasonable layout of robust upper frame optimizes the utilization of steels.
Undercarriage
The X-shaped undercarriage with heavy-duty box structure is subjected to the repeated analysis and calculation, it enhance the
overall rigidity, strength and tortion resistance. Undercarriage is welded from the low alloy structural steel plates with overall
process quality control. The critical welding seams are fully subjected to fault detection and stress test to ensure the product
quality & durability.
Track
There are intensified ribs and crawler cradle in the middle of the track links. Using M-type oil seal 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 driving motor gear ring 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 guarantees the high pressure sealing inside the cylinder block,
the tensioning 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.
Windows
The glass is clung to the cabin 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 cabin pillar enlarges the operator's field of view, it allows the continuous and intermittent
operation modes.
Safe and Comfortable Cab
The spacious and multi-functional cabin designed according to ergonomics enhances comfort for operator. The reasonable layout of
control elements inside the cabin allows easy operation.
Standard Cabin Equipment
The cabin inside includes the cigar lighter, ashtray, 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 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 joy stick is located at the outside of left armrest box in the cabin. 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 heavy load during operation, the design & development team of LONKING adopts lots of up-to-date design ideas,
preserves the higher safety factor, employs repeated 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.
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. Standard bucket with flat-floor which is praised by users is
more suitable for the leveling conditions. This excavator provides different bucket options to meet different working demands.
Easy Maintenance and Service
The design and layout 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 to the outside of machine to facilitate the maintenance.
Long Maintenance and Service Cycle
The maintenance and service cycle has been prolonged to reduce the maintenance parts collection and enhance the availability.
