Speaking of construction machinery, the first thing that comes to mind is the concept of giants. In fact, in recent years, especially in the development of the construction machinery industry in 2010, China’s construction machinery products are gradually moving from medium-sized products to miniaturization and large-scale development. There is a great potential for polarization. Among them, excavators, skid steers, backhoe loaders, and rotary drilling rigs are the most obvious.

The development of the Chinese construction machinery industry toward large-scale development has great significance in further improving work efficiency, especially in the fields of energy, wind power, nuclear power, etc. The trend of large-scale production is very obvious, among which the development of crawler cranes is particularly prominent. . The launch of the 1,000-ton large-tonnage crawler cranes such as Sany, Xugong and Fushun has not only completely eliminated the situation that this type of product is completely dependent on imports, but also fully proves the technical level and manufacturing capability of domestic production enterprises. To a large extent, China's large tonnage cranes have enhanced their market competitiveness. During the "12th Five-Year Plan" period, there will be more large-scale products in this area to replace traditional products.

On the other hand, products such as excavators, skid-steer loaders, and backhoe loaders are also starting to move toward miniaturization. For the Chinese construction machinery market, the development of small construction machinery has only just begun. With the continuous deepening of the concept of energy saving and emission reduction and green environmental protection, along with the continuous improvement of people's requirements for construction fineness, the trend of miniaturization of construction machinery products will continue to grow. In the field of small construction machinery, foreign development has been rapid, with JCB, Case and other fastest. Among local Chinese companies, Liugong, Shanhe Intelligence and other companies have also started to make efforts on small construction machinery products. During the Shanghai Baoma Exhibition in 2010, Sany's small pure electric hydraulic excavator made a stunning appearance, which symbolizes that the research and development level of Sany Heavy Machines has raised a new level, and it also strongly promotes the development of new energy technologies in the construction machinery industry. It is reported that the 31 small pure electric hydraulic excavator will be mass-produced in 2011. In 2011, at the beginning of the new year, Komatsu launched a new 5.2-ton compact excavator PC55MR-3 in the European market, which greatly reduced the operating strength of the subsidiary tooling. Industry professionals expect that the spring of the small construction machinery market will come during the “12th Five-Year Plan” period.

During the “Twelfth Five-Year Plan” period, relying on the construction of large-scale national projects, the rapid progress of infrastructure investment and urbanization, the momentum of large-scale development of construction machinery products remains strong, and the requirements for energy-saving emission reduction and construction refinement are constantly increasing. With the increasing popularity of micro-engineering and mini-engineering, miniaturization of construction machinery products will certainly open up new horizons. In this way, during the “12th Five-Year Plan” period, the “two-level differentiation” of construction machinery market will gradually be opened.
