目前筑路小型液压挖掘机在迅速的发展,在技术上也在不断成熟。筑路小型液压挖掘机一般是指整机质量在5t 以下的液压挖掘机,在欧洲、美国、日本、韩国都有一些著名的大企业在生产液压挖掘机,筑路小型液压挖掘机已成为公路建设中的重要产品,因此其产量所占的比例越来越大。在日本其产量达5万台左右,欧、美等国家也约有2万台左右的产量。1、筑路小型液压挖掘机技术特点(1)体积小、重量轻、功能齐全、转移方便。(2)技术性能高。现代液压挖掘机的设计制造技术在筑路小型液压挖掘机上得到很好的发挥,机电一体化技术、工业造型技术等得到了广泛应用。工程塑料等新材料、新工艺不断在采用。
At present, the construction of small hydraulic excavators in the rapid development of technology is also constantly maturing. Road construction small hydraulic excavator generally refers to the whole machine below 5t hydraulic excavator in Europe, the United States, Japan, South Korea have some of the famous large enterprises in the production of hydraulic excavators, road construction of small hydraulic excavator has become a road The important product under construction, so its share of production is growing. In Japan, its output reaches about 50,000 units, and about 20,000 units in Europe, the United States and other countries also produce about. 1, road construction of small hydraulic excavator Technical Features (1) small size, light weight, full-featured, easy to transfer. (2) high technical performance. The design and manufacturing technology of modern hydraulic excavator has been well exerted on the small hydraulic excavators in road construction. The mechatronics technology, industrial modeling technology and the like have been widely used. Engineering plastics and other new materials, new technology continue to be used.
