一机部天津工程机械研究所和宜春工程机械厂于1977年到1978年设计并试制了ZL30装载机(照片见图1),并对样机进行了500小时工业性试验和整机性能测试。试验证明,样机工作可靠,各项性能指标达到设计要求。该机总体布置合理,结构紧凑,性能良好,操纵轻便,作业效率高,外形美观大方。1978年12月在江西宜春,一机部重型矿山机械总局主持对样机进行了鉴定定型,由宜春工程机械厂小
The first machine department Tianjin Engineering Machinery Research Institute and Yichun Engineering Machinery Plant designed and trial-produced the ZL30 loader from 1977 to 1978 (see photo in Figure 1), and conducted 500 hours of industrial testing and performance testing of the prototype. Tests have proved that the prototype work is reliable and all performance indicators meet the design requirements. The overall layout of the aircraft is reasonable, compact structure, good performance, easy operation, high operating efficiency, beautiful appearance. In December 1978 in Yichun, Jiangxi Province, the Ministry of Heavy Machinery and Machinery of the Ministry of Mines presided over the identification and finalization of prototypes, which was designed by Yichun Engineering Machinery Factory.
