China Construction machinery information

on February 19, the Shandong Provincial People's government issued a notice on Issuing the list of 2016 provincial key construction projects due to the increasingly strict domestic environmental protection work in the form of LUZHENG Zi [2016] No. 41, The industrialization project of large-scale energy-saving and environmental friendly hydraulic excavator of Shandong Changlin group has been successfully selected

the project can achieve an annual output of 5000 large-scale energy-saving and environmental friendly hydraulic excavators. The technology source of the project is independent research and development, with independent intellectual property rights. The advent of this hydraulic excavator is a disruptive revolution to the traditional excavator. This product fills the domestic gap and has the ability to replace imported products. This machine adopts hydraulic energy storage technology for energy recovery, and provides energy to the load as an auxiliary power source and an active power source. It is a new type of hydraulic hybrid excavator; Using the high-efficiency hydraulic parts specially developed by Zhongchuan hydraulic for the energy storage structure, combined with the deep understanding of Changlin group for excavators, the whole power flow is optimized and re matched, and the design goal of high efficiency, energy conservation and environmental protection is achieved

this project is a directional product for the development of the excavator industry. 1. The fluctuation range of the power supply voltage should not exceed ± 10% of the rated value. It fills the technical gap of the domestic hydraulic excavator and becomes a real creation in China. The product has reached the international leading level of similar products. This project is fully in line with the national economic development policy and the local economic development plan. It is a preferred project to revitalize China's national industry and enhance the national and local economic strength for the benefit of the country and the people. It will actively promote the development of enterprises and the technological progress of products, and its internal structure will not be destroyed
