Nearly five years, as the development of the national income, construc-tion machinery develop so impetuous that its position changes tremendouslyin construction and manage, and its scale becomes lager and lager in the total of the capital in construction enterprises, so the whole-ratio of equip-ment and its using-life are becoming more and more closer to the economybenefits of the enterprises. As the strength of the market of construction machinery, the maintenance-repair managing engineering will develop certain-ly. But in our country, Planned Anticipate Repair System is the main re-pair system.Its positive effect has assured the whole-ratio of machinery and technology, but more problems are existing, such as the limitation of its foundation, the time of maintenance and the working content, the correct of machinery running and more circulating fund using reserved-replacements. In this time,the main problems in construction machinery repair-market are lately start, tethnics out of data, short of person with ability, without apply of new produce and technology, impertinency of repair and serve, short of check-up of repair evaluation and intendance system, without uni-form charging-standard and unfair compete. If we analyse the condition of construction machinery maintenance, we will find more incommensurate problems aiming at this condition, such as repair manage mode off time, repair manage system distemperedness, slowly manage technology,lack of safety and short of repair manage base equip-ment. We have to depend on person with ability to manage the construction machinery and improve economy effect of enterprises, but the resource of manpower of some enterprises can't fulfill the requirement of construction machinery maintenance. Impertinency of manpower ordonnance, low-level technology, short of value to technology and lower pay are the condition of the technology of construction machinery maintenance. This paper presents some propositional countermeasures to construction machinery maintenance, such as setting up perfect market of construction machinery, strengthing apply of repair manage engineering, attaching import-ance to the earlier manage of equipment,optimizing spot manage and bring-ing up sorts of person with ability. The mode of Reliability Centered Maintenance is a kind of advanced maintenance mode basing on common condition maintenance. The service of Reliability Centered Maintenance based on the mode of RCM is effective means to improve economy effect of enterprises and so-ciety and the known and position of enterprises, it can improve the level of operating the machinery and the pay of person with ability. There are more factors and administrative levels in the evaluation of the service of Reliability Centered Maintenance. Fuzzy evaluation of expert is simple, but the balance of evaluation factor is difficult to assign and runs short of veracity. And Improved Analysis of Hierarchy Process can balance the short which has noticed above. This paper uses two methods to analyse those problem and improves the analyse ways. The system of evaluation target effects on evaluation quality, so how to set up scientific,applied and reliable system of evaluation is the best key problem to the service of RCM of construction machinery. Generally speaking, the choosed parameter target must image the condition of the ser-vice of RCM of construction machinery . There is a good method to solve the existent problems in the service of RCM, that is improving the level of the service of RCM in enterprises.
