As human production and life develop towards high energy consumption, the environmental cost increases, leading to increasingly prominent environmental problems. The enhanced environmental awareness has led to higher demands for environmental protection. In recent years, the construction industry has developed rapidly and has become a major pillar industry in China. Therefore, related construction machinery, such as hoists, should comply with environmental protection and resource saving requirements throughout their life cycle from manufacturing to scrapping. Hence, Nantong Liwei proposed the suggestion of achieving green buildings and green construction machinery, Environmental protection and energy saving should become a principle that social development must follow. In the design, manufacturing, and use of construction machinery, it is also necessary to optimize and improve various aspects of design, manufacturing, use, and management, enhance the effectiveness of environmental protection and energy saving, and reduce pollution. Promote the synchronized development of economic growth and environmental protection and energy saving. This is a goal that the entire industry needs to strive for together as China industrializes. China's economic growth can only achieve sustainable development if it is coordinated with environmental protection and effective resource utilization.
1. Development Status of Hoist Construction Machinery
According to relevant plans, China actively implements the strategy of invigorating the country through science and education, continuously increases scientific and technological investment in environmental protection, develops environmental protection industries, vigorously promotes energy-saving and consumption-reducing technologies, advocates cleaner production, and relies on scientific and technological progress and technological innovation to promote economic development and environmental governance and improvement.
After more than 50 years of development, China's construction machinery industry has grown into an industry with over 20 product categories and an annual output value exceeding 100 billion yuan, also holding a certain influence in the global construction machinery market. With the continuous increase in the variety and quantity of construction machinery, the resources consumed, pollutants emitted, and noise and dust generated during construction by a large amount of construction machinery have placed an immeasurable burden on the environment, yet it has not completely broken free from the traditional model of high energy consumption, low efficiency, heavy pollution, and extensive development. Developed countries' construction machinery has entered the information development period, with widespread attention paid to energy saving and environmental protection, safety technology, automated control technology, visualization technology, ergonomics, fault diagnosis and monitoring systems, and cluster operation information and control, and corresponding technical standards have been introduced.
China's environmental protection and energy-saving construction machinery started late, and there is a lack of corresponding technical regulations and standards. Indicators related to environment, safety, and human-machine interaction are too low, hindering the development of green construction machinery in China. In recent years, international trade disputes are gradually shifting from tariff barriers to environmental barriers. "Environment" has become a new factor restricting and limiting trade liberalization. The design and manufacturing of construction machinery products must consider adapting to the requirements of environmental and ecological development. Developing and researching environmentally friendly and energy-saving products is the future trend of construction machinery development.
2. Environmental Protection Concepts for Hoists and Other Construction Machinery
The development of environmentally friendly and energy-saving construction machinery must comply with national industrial policies. A mechanical product, no matter how good its performance, has no development prospects if it does not meet environmental protection requirements. At the same time, the development of environmentally friendly and energy-saving construction machinery is inseparable from the transformation of construction technology and construction processes. Hoists and other construction machinery should increase scientific and technological investment, renovate existing machinery, provide environmentally friendly machinery, reduce environmental pollution caused by mechanical operations, reduce the energy consumption of machinery, and strive to achieve environmental standards such as low consumption and low pollution.
Currently, China's sales volume and sales value of hoists and other construction machinery have surpassed those of the United States, Japan, and Germany, ranking first in the world; the output of excavators, loaders, bulldozers, truck cranes, road rollers, concrete machinery, tower cranes, forklifts, and other products has jumped to the top globally, making China a major manufacturing country for construction machinery in the world. Therefore, vigorously researching and developing green and environmentally friendly machinery is an urgent matter.
