Lonking LG6225NS Tunnel-king crawler hydraulic excavator

1、Standard CumminsQSB6.7 Engine，Meet the third national emission standard，The power is stronger；

2、Kawasaki configuration for main hydraulic components；

3、Kawasaki positive flow control system，The control is more precise，Higher operational sensitivity；

4、A plurality of electro-proportional valves are adopted to realize controllable priority and regeneration functions.， Improved speed and movement coordination；

5、Valve block is controlled by proportional solenoid valve，Fast switching，Sensitive, soft and small impact；

6、Full upgrade of cooling system，Significantly improved cooling capacity，Ensure that under various working conditions，Temperature stabilization of the engine and hydraulic system，Extended engine and hydraulic system life，Ensure the reliability of the whole machine、Stability，Greatly reduce the noise and vibration of the whole machine；

7、New Cab with Deluxe Suspension Seat，Ergonomically optimized force and structure of the pilot control system，The operation fatigue of the operator is greatly relieved.；

8、Fully optimize the process of structural parts，Solidification process and parameters、Full use of high-performance welding robots for automated welding；

9、Reinforcing ribs are added inside and outside the bucket，Higher strength of bucket bottom，Heavy duty side teeth are used、Thickened side panels，Dou is stronger、More wear resistant。Optimized design of bucket shape and cutting angle，More suitable for efficient excavation and handling，Maximize mining efficiency，Save fuel consumption；

10、The cross section of the working device adopts a reinforced box-type structure.，Larger cross-sectional area，Forge welding structure is adopted for the working device，The intensity is higher；

11、Boom and arm cylinders are equipped with a new type of shaft sleeve with high surface hardness and double-layer anti-wear measures with oil storage holes.；

12、Non-suspension stop valve with mounting bolt shall be used for crushing pipeline.，The fixation is more reliable；

13、Add bucket cylinder guard，Adopt a reinforced arc-shaped plate to be support by two inclined surfaces，The protection is more reliable；

14、Comprehensively improve the reliability of each hinge point，And that hydraulic Los is reduced，The stability and durability of the structure are realized.；

15、The bottom sealing plate of the platform is fully enclosed.，Effective response to tunnel environment，A small cover plate which is easy to open is locally arranged at the maintenance position.，And is convenient for maintenance；

16、The chassis is widened，Vehicle performance is more stable；

17、The whole machine is equipped with 360-degree panoramic camera as standard.，Easy handling of tunnel conditions，Safer driving of the whole machine；

18、Display and control system upgrade，Kawasaki is used as the main controllerKC-MB-21，The operating speed cycle is 20ms，Much higher than 40% of the same industryms，Higher reliability，More accurate power matching，Significantly reduce fuel consumption；

19、Through the optimized arrangement of maintenance parts，O that daily maintenance is time-saving and labor-saving；

20、The whole machine provides two color combinations for users to choose.；
