Lonking 22 Ton Hydraulic Stone Breaker Crawler Excavator With 1Cbm BucketCDM6225
Product Overview
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.
Filtering System
The high efficiency dual 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 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 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.
