一、什么是工程机械工程机械是机械工业的重要组成部分,它与化工设备、金属切削机床、矿山机械、冶金压延设备、起重运输机械、仪器仪表、汽车、拖拉机以及电工设备等行业一起,共同组成机械工业体系。约于二十世纪初期,工程机械在工业较先进的国家,发展成了专门的行业;二次世界大战以后,发展尤为迅速。在我国,工程机械发展较晚,目前还是一个很薄弱的行业,很多人对它尚不十分了解。究竟什么是工程机械呢?概括地说:凡土方工程、石方工程、露天起重装卸工程以及各种建筑工程,粽合机械化施工所必需的主导装备,称为工程机械。所谓土方工程,一般包括对土壤的疏松、挖掘、
I. What is engineering machinery? Construction machinery is an important part of the machinery industry. Together with chemical equipment, metal cutting machine tools, mining machinery, metallurgical rolling equipment, lifting and transport machinery, instrumentation, automobiles, tractors, and electrical equipment, etc. Together constitute a mechanical industrial system. Around the beginning of the 20th century, construction machinery developed into a specialized industry in countries with more advanced industries; after the Second World War, development was particularly rapid. In China, the development of construction machinery is relatively late. At present, it is still a very weak industry, and many people are not yet fully aware of it. What exactly is a construction machine? Summarized: Every earthworks, stone works, open-air lifting and loading and unloading projects and various construction projects, and the necessary equipment for the construction of mechanized construction are called construction machinery. The so-called earthworks generally include the loosening and excavation of soil.
