Revo FR480E excavator, as one representative of Loeb Heavy Industries' large-tonnage excavator, is another fruit of Lovol Heavy Industry's global R&D system. The Revo FR480E excavator is based on the Revo Engineering Machinery Japan R&D Center, which is led by a Japanese expert as a project manager and a brand-new development in accordance with the HIPDP product creation process.

"Standard 2.1m3 rock bucket, the whole machine working quality 46000Kg, positioned in heavy duty conditions." Revo FR480E excavator is a star product of Lovol Engineering Machinery Group, product configuration is high-end, performance reaches the domestic advanced level, strong and powerful, High reliability, low fuel consumption, and good handling.

Sawada Yujiu is an excavator R&D engineer from Japan. To be precise, he is an expert in "fever" class hydraulic systems. He has been insisting on the development of hydraulic systems for excavators for more than 30 years. The annual work of the hydraulic system team is to invest tens of millions of yuan in research and development funds, bringing together all the cutting-edge scientific and technological achievements in one product.

As the head of the R&D project of the Revo-FR480E excavator, he had a hard time in the early stages of R&D. At that time, in order to meet the needs of mining heavy working conditions, the research and development team was transferred to major coal mines, cement mines, and metal mines across the country for research and understanding of customer needs.

Most of the mine sites are located in mountain areas and in remote villages, and the working environment is rather harsh. In order to obtain the most realistic and valuable research information, the project team often stays in the mine for a few days. Once, in a coal mine in Inner Mongolia, because of its remote location, accommodation and catering could not be solved. The project team lived on the mine, which lasted for more than two months.

The Revo FR480E excavator combines the advantages of robustness, reliability, low fuel consumption and good maneuverability. The design of the hydraulic system is one of the tasks that the project team spends most time and energy on, and is one of their most proud masterpieces.

In the early stages of development, the project team organized a regular exchange meeting every day to gather together their own ideas and ideas on how to design a hydraulic system. Any new ideas would make project members excited. They even quarreled over a certain point of view. With the continuous efforts of the team, the large-tonnage Revo FR480E excavator was born.

Any innovation can not be separated from the fear of breaking, but also can not do without the unremitting efforts and persistence of the R & D team. The project members said: "With two years of research and development, we have achieved tremendous growth in the project and we have also understood the importance of mutual cooperation. Our friendship has become more profound."

Sawada Yukio sighed and said: "For so many years dealing with the hydraulic system is like tea, the technical problems of the hydraulic system have been solved a little bit, like the refreshing blooming of tea fragrance. Hydraulic technology is the technical foundation of the excavator and its excellent performance. The poor determines the working performance of the excavator.Because Revo FR480E excavators are mostly used in heavy conditions, the requirements for power and stability are very high.If you want to understand the problem and optimize it, you need to completely calm down and listen. It feels like smelling before tea, and the R&D process is like drinking tea and cannot be done in one go. It requires careful thinking about the product's performance, reliability, and user experience."

A good product research and development is not a day's work. The Revo FR480E excavator is a star product of Lovol Engineering Machinery Group. It is even more necessary to interpret classics and achieve extraordinary results. Leading the trend of the construction machinery industry, more is a little-known story.
