| The 4m3 electric excavator is one of the major equipment at present in the open mine in our country. The security and reliability are very highly required, which play a very important role in whole system of the open mining. With the rapid development and advance of excavator manufacture industry, the requirements of maintenance control are higher and higher. At present the important subjects of the middle and small open mine enterprise are how to suit the new situation, how to improve the maintance control system and maintance technology, and how to ensure the security reliability and economy operations of the excavator.This article give a series of optimized maintenance improve methods of frequent faults and innovate technology, in researching of the 4m3electric excavator, based on the introduce of excavator development status in domestic and overseas and according to the summary of experience of maintenance manage. I put forword and apply the advanced manage technique and maintenance technology to the 4m3electric excavator, such as critical path technique,the section-mutual-change technology; centralized grease lubrication system, maintenance model, all applied in practical works of the excavato maintenance, ensure the security produce, reliability operations and economy maintenance of the excavator. This subject is based on the practical experience of the 4m3electric excavator of the mining company of the Shandong branch of China's aluminium industry CO, LTD, can effectively prolong its life-cycle, reduce its maintance cost, and got very good results in technology and economy. Some improves get preferably purpose about zero trouble hour. These efforts are of extending and applying value according to practice. At the same time, as prophase results in studying and working to the section-mutual-change technology and lubrication technology, it will provide a beneficial flat roof of deeper studying link to the section Re-manufacture and lubrication repired-self technology. |
