Construction machinery is the main equipment for national defense construction and road construction. With China's modernization and high-tech construction machinery in a wide range of applications, a large number of high-tech, superior performance, advanced technology to enhance the older generation of construction machinery more and more into the construction enterprises, construction companies to ensure that the progress of progress and progress of enterprises The economic benefits and enhance the competitiveness of enterprises has played a very important role. However, at present, the problem of serious and backward construction machinery maintenance and management work is also exposed more and more prominently. It is of great significance to maintaining the good technical condition of construction machinery, fully exerting the best performance of construction machinery, completing construction on time, Impact. Based on the investigation and analysis of the construction machinery maintenance status of the construction enterprises at present, combined with the details of the maintenance and management of the unit, this article finds out the problems existing in the construction machinery maintenance and management and puts forward the basic countermeasures. Construction machinery maintenance and management problems 1.1 The use of light maintenance Because of the arduous and complex construction machinery maintenance work, so that some units on the construction machinery management, maintenance of the importance of lack of knowledge, ignoring the construction machinery necessary maintenance work, In the course of construction machinery used in the pursuit of short-term benefits of behavior, making construction machinery sick, extreme wear and tear parts, the result of engineering machinery failure increases, the service life is shortened. 1.2 rebuild light changes in the construction machinery repair process. Many units only "recovered for the sake of seeking truth" and did not carry out the necessary technological changes. As a result, old construction machinery still consume more fuel and have lower efficiency. 1.3 The premise of the repair site difference because of the large construction machinery mobility, coupled with poor construction site conditions, once the construction machinery failure, the general is the original demolition, repair, demolition of the parts easy to rust, damage or loss, not easy to keep parts The cleaning, it is difficult to ensure the quality of maintenance. 1.4 parts supply is not timely There are varieties of construction machinery, hybrid models, coupled with the homework area is a backcountry, traffic inconvenience, resulting in the purchase of construction machinery repair parts problems, parts ordering cycle length, extending equipment downtime. 1.5 weak maintenance technology weakness Currently there are maintenance staff in construction enterprises less than the number of staff, activity characteristics, coupled with the theoretical level of some maintenance staff is low. Resulting in difficult problems of some construction machinery difficult to solve, the quality of the repair is difficult to guarantee.
