According to Chinese standards, construction machinery is classified into the following types: (1) excavation machinery: including single bucket excavators, multi bucket excavators, and excavation loaders. (2) Earthmoving machinery: bulldozers, scrapers, tippers, etc. (3) Compaction machinery: including road rollers, compactors, etc. (4) Engineering lifting machinery: including tower cranes, crawler cranes, construction elevators, etc. (5) Piling machinery: including vibrating pile hammers, hydraulic hammers, pile presses, etc. (6) Road machinery: including asphalt spreaders, asphalt concrete pavers, etc. (7) Concrete machinery: including concrete mixers, concrete mixer trucks, concrete pumps, etc. (8) Concrete product machinery: including concrete block forming machines, hollow slab extrusion forming machines, etc. (9) Reinforcement and prestressing machinery: including reinforcement machinery, reinforcement forming machinery, reinforcement connection machinery, reinforcement prestressing machinery, etc. (10) Decoration machinery: including mortar preparation and spraying machinery, paint spraying machinery, ground finishing machinery, decoration baskets, handheld motor tools, etc. (11) Aerial work machinery: including aerial work vehicles, aerial work platforms, etc. Notes: With the development of the construction industry, the degree of mechanization of construction construction is increasing year by year. The continuous development of mechanization in construction has promoted the reform of construction technology, the emergence of high-rise buildings, and the promotion of new construction techniques, which has also promoted the further development of construction mechanization. Due to poor construction conditions and variable environments, which are different from the production processes of general indoor operations and fixed equipment, machinery is prone to wear and tear, maintenance is inconvenient, and there are many unsafe factors. In addition, frequent changes in operators and users can lead to incorrect use and continuous summarization of the safety operation rules of various types of machinery, which not only shortens the service life of the equipment and reduces efficiency, Moreover, equipment accidents and personal injury accidents are prone to occur, so before using various types of machinery, it is necessary to have a correct and comprehensive understanding of their performance and safe operation methods, and use them correctly according to the original design and manufacturing requirements.
