Recently，Guangxi Liugong Machinery Co Ltd（Hereinafter referred to as：Engineer Liu）Take the lead“Key Energy-saving Technology and Application of Hydrostatic Loader”“Key Technology and Application of Hydraulic System of All-wheel Drive Motor Grader”It has successfully passed the on-site appraisal organized by China Machinery Industry Federation.，The technical level has reached the international advanced level.。

“Key Energy-saving Technology and Application of Hydrostatic Loader”The project started in August 2014.，It took eight years，The key technology of energy saving for hydrostatic transmission loader is systematically studied.。In the project，Liugong has established a complete set of design methods and theories for hydrostatic drive.，A test platform for hydrostatic drive of loader is built.，Developed and completed a series of gearbox products with independent intellectual property rights。

At present，The results of the project have been applied in batches to wheel loaders and other earthmoving machinery.，To achieve energy conservation and emission reduction“Double Carbon”The goal has contributed an important force.，Produce significant social and economic benefit。

“Key Technology and Application of Hydraulic System of All-wheel Drive Motor Grader”The project started in January 2016.，It took six years，The project has carried out systematic research on the key technologies of the grader.，The front wheel drive control of motor grader is proposed.、Optimization design of shovel blade device, etc.，And that work efficiency of the grader is improve.，The project results have been applied toDSeries grader products。
