水电部夹江水工机械厂,于1980年试制成了HB30型混凝土泵,并于1981年通过了工地试验和水电部鉴定。1982年初开始批量生产,这种混凝土泵已普及到全国六大区十二个省、市的许多水电、火电建设工地。HB 30型混凝土泵采用电动机——液压驱动,双缸,拖车式,其外观如图1所示。
The Jiajiang Waterworks Machinery Plant of the Ministry of Water and Electricity, in 1980, commissioned the HB30 concrete pump and passed the site test and the identification of the Ministry of Water and Power in 1981. Mass production began in early 1982. This type of concrete pump has been widely used in many hydropower and thermal power construction sites in 12 provinces and cities in six regions of the country. The HB 30 concrete pump uses a motor-hydraulic drive, twin-cylinder, trailer-type, and its appearance is shown in Figure 1.
