Stand up to the tide，Dare to be the first。With“Guo Si”Countdown to standard implementation，As the industry leader, Engineer Liu took the lead.，The whole series of products are ready to fully switch to the fourth non-road country.，More and more national four equipment are delivered all over the country.，Win the unanimous recognition and trust of customers。
Handover is hot
A single product line has sold more than 1000 units in two months.，Liugong Guosi Equipment with High Praise，It relies on the technical reserve of one step ahead of others.、Verification and polishing in overseas markets and reliability verification under extreme working conditions。
One step ahead of others
Comprehensive acceleration of the fourth national upgrade
Back in 2017，Engineer Liu opened it in.“Guo Si”R & D and reserve in the field，It is the first construction machinery enterprise in the industry to start this research.。After nearly five years of experimental development,，Engineer Liu has accumulated the first-mover advantage of engine aftertreatment products.，At the loader、Excavator、Motor Grader、Bulldozer、Skid Steer Loader、Take the lead in the research and development of all products such as Road Roller，Striding into the Fourth National Era of Construction Machinery。
The fourth national experience officer（Handheld test）
Nowadays，Liugong has taken the lead in realizing the upgrade iteration of the fourth series of national products.，Continue the advantages of the third national products while integrating into the requirements of the fourth national emission environmental protection regulations、Customer requirements and intelligent configuration，The optimization of family product type spectrum and the overall improvement of product comprehensive performance are realized.，Better overall efficiency、Lower fuel consumption、Higher reliability。
Stones from other hills
Proven overseas markets
Before putting it into the domestic market.，Liugong four-stage products have been used in batches in overseas markets.，It has been continuously verified and polished in the European and American markets that have already implemented the fourth phase of European emission standards.。
In fact，Cummins carried by some products of the fourth national series of LiugongL9 engine has been implemented for many years in European and American countries.，Engine and aftertreatment over decades、Verification of millions of units，Non-road fourth with Europe、The combination of the five stages and the iterative technology of the six stages of Vehicle use.，At“Fuel saving”、“Efficient”And other issues have made major breakthroughs.。Based on a proven power platform，Liugong entering the international market，Close to customer needs，Continuously increase R & D investment，And fully benchmark the international level.，The comprehensive performance of the product has reached the advanced level of similar products.。
“Guo Si”Implementation of emission standards，After-treatment system reliability is critical to the overall operation of the machine。The post-processing system carried by Liugong equipment has been fully verified in the European and American markets.，Reliability is guaranteed，Built-in non-perceptive soot cleaning function，Intelligent regeneration without downtime，Operational efficiency has been greatly improved。
Strength certification
Calmly cope with harsh working conditions
It has been verified and polished by overseas markets for a long time.，Engineer Liu has accumulated rich experience in the research and development of China IV products.，It also laid a solid foundation for the fourth national upgrade of domestic products.。Responding countries“Double Carbon”Policy，Satisfy“Guo Si”Emission standards，Engineer Liu is one step ahead of others.，Carry out the field working condition test of the whole series of products of the Fourth National Congress throughout the country。
Proving ground reliability testing
Guangxi Cummins carried by Liugong Guosi LoaderL9 Special engine for construction machinery，It has passed the road test verification of 50000 hours of reliability under the extreme working conditions.，Nearly 10000 hour bench test；Liugong loader、Excavator Experimental Team Went to Mohe, Heilongjiang、The Sichuan-Tibet Plateau and other places are cold and cold.、Test under extreme conditions such as plateau，It has been tested for 30000 hours under harsh working conditions in large open-pit coal mines in Inner Mongolia.，Stand-alone verification 5000 hours operation test，Ensure the reliability and safety of the fourth national product。
Low temperature test in Mohe, Heilongjiang
Proven for a long time，The fourth equipment of Liugong State is in the high and cold climate.、High altitude、Good stability in severe working conditions such as high dust，Successfully passed the altitude of 4500.mExtreme working condition of plateau、-45℃Extreme cold working condition、Reliability verification under heavy-duty working conditions, etc.。
Extreme environment test of Sichuan-Tibet Plateau
“Focus on customer needs，Create ingenious products”，Engineer Liu never forgot his aspiration.，In terms of technological breakthroughs and reliability improvement，Continuous pursuit of better user experience and greater benefits。Future，Engineer Liu will“Guo Si”Upgrading as a new starting point，Continuously achieve key core technology research，With high-quality products and all-round intimate service，Bring new solutions to customers around the world，Create greater value for our customers in the fourth era of construction machinery。
