How to Manage and Use Construction Machinery

Construction machinery is commonly used in industries such as building construction, water conservancy, power generation, development, and road construction, and is an important component of China's equipment industry. With the development of China's economy, mechanized construction has become increasingly common. The widespread application of construction machinery in construction has greatly improved construction efficiency and quality. However, in the use of construction machinery, various factors and the influence of the external environment greatly restrict its use. How to obtain the greatest economic benefits at the lowest cost requires consideration of the factors affecting the management and use of construction machinery. This paper introduces the current status, characteristics, existing problems, and effective measures and methods of construction machinery management and use, summarizes the requirements for construction machinery management and use, and thereby extends the service life of construction machinery.
