Double steel wheel roller 6212EG4、6213EG4、6214EG4 Three items，12 tons respectively、13 tons、14 tons，It can meet the requirements of various pavement materials and construction processes.，Adopt flow ball type flexible non-impact technology、Double-pump and double-motor vibration technology、Three-stage damping technology、Intelligent independent cooling technology、“Soft start，Soft braking”Technology，And has high reliability、Low noise、And that service life is long、And that operation efficiency is high、Ood flatness and the like.，Compared with previous products，Fuel saving performance increased by 10%，Fully meet the compaction requirements of various working conditions。

Released 26 tons and 30 tons of two tire rollers.，The model is 6526EG4 and 6530EG4，Its rated power reaches 140kW，Rated at 2200 rpm/Minute。The maximum driving speed reaches 15 kilometers./Hour，The maximum operating mass is 26000.-30000kg。Mainly applicable to asphalt concrete、Compaction construction of dry and hard cement concrete pavement，It can also be rolled and sticky.、Semi-viscous、Basic layer materials such as sandy mixture。Advanced high pressure common rail and exhaust aftertreatment technology，Meet the fourth national emission，Energy saving and environmental protection；Panoramic view and dual cab platform system，No blind area for edge pressing operation，Good sealing performance of the cab，Low noise，The operation is convenient。Good compaction efficiency and quality，Ensure construction safety through various preventive and protective measures。

The newly launched Liugong 4165DG4、4180DGGrade 4 leveling function adapts to various harsh working conditions，Comfortable operation、Convenient transshipment、The passing performance is good，And that construction efficiency is high。

Maintenance equipment highlights frequently

In addition to a complete set of pavement construction solutions,，There are also various pavement maintenance equipment to meet the fourth national emission.，It can be called a bright spot.。

As“High-grade pavement milling expert”YesM100EG4. The maximum milling depth of the milling machine is 22 cm.，Equipped with Dongkang 154KWEngine，Maximum torque up to 820Nm，Can adapt to various working conditions.，Available at high altitudes、Continuous operation in high temperature and extremely cold environment。Key hydraulic components are purchased from imported brands，And that reliability is high，And that service life is long，It has strong power、Be flexible、Energy saving and high efficiency、Convenient and quick and the like.。

6033EGSmall-sized hydraulic tandem vibratory roller has larger exciting force and higher vibration frequency，It has good maneuverability and excellent control performance.，It is mainly used for the repair of asphalt pavement, the compaction of sidewalks and bicycle lanes, and landscaping projects.，It is also an ideal equipment for supporting construction with heavy rollers in large-scale construction projects.。

In addition，There are also skid steer loaders that meet the fourth national emission.、Propeller and other products，It was warmly welcomed by users at the product exhibition site.。

The grand launch and full listing of the fourth national product，Liugong Road Machinery actively practices the national environmental protection policy.，Stick to it“Double Carbon”Excellent results of the development strategy，It provides a wealth of green construction solutions for the majority of road builders.，For Liugong Road Machinery to better manage the market in 2023、Building an international leading brand of road construction machinery will have a far-reaching impact.。
