Construction machinery
Construction machinery, also known as engineering machinery, is a kind of machinery and equipment used for engineering construction. Construction machinery is mainly used for commercial, civil engineering and infrastructure construction. It is divided into earthwork machinery, lifting machinery and other machinery. Earthwork machinery includes bulldozers, excavators, loaders, motor graders, road rollers, scrapers and other machinery; lifting machinery includes tower cranes, hoists, cranes, cableway cranes and other machinery; other machinery includes various road construction machinery, pile machinery, pile driving machinery and other specialized machinery.
The construction machinery market is huge in scale and highly diversified, with a large number of manufacturers, a wide range of models, specifications and prices. Construction machinery can be divided into three categories according to the layout of power transmission and working mechanism: bulldozer, excavator and hoisting machinery. Nowadays, large-scale and efficient construction machinery, such as crawler cranes, truck cranes, branch cranes, tower cranes and other large and medium-sized cranes, etc., are widely used in modern construction projects.
Regard to the structure of construction machinery, there are two basic types of structure, the partial or distributed structure and the integrated structure. As far as power transmission, the state’s current stringent control of exhaust emission and noise standards has led to the application of more advanced electronically controlled and clean energy engines in construction machinery. In addition, in order to ensure the driving stability and improve the working efficiency of construction machinery, a variety of control systems are also commonly used in construction machinery, such as proportional pressure control systems, mechanical, fluid and electronic control systems, etc.
In modern construction projects, construction machinery often becomes the main unit in production automation and serves as the basic mechanical equipment of engineering construction. However, the safety and efficiency of modern construction machinery has a great impact on the production efficiency of the entire project. In order to promote the safe, convenient and efficient application of construction machinery in construction projects, it is necessary to carry out continuous research and innovation in the design, manufacturing, operation and maintenance of construction machinery in order to constantly improve the performance and adaptability of the construction machinery and make it more applicable to the current construction projects.
