为解决施工现场1吨机动翻斗车的散状物料机械装车问题,我们配合北京市第六建筑工程公司二工区,先后试制成功了丰收-35型和Z_3J-06型液压装载机,但鉴于一无基础底盘、二无成品部件,另外主要配套件来源亦有困难,未能得以推广。因此于1976年6月我们又继续进行了装载机的研制工作,经过半年多时间的努力,终于又试制成功了Z_3-04型液压装载机(图1)。 In order to solve the problem of mechanical loading of bulk materials on a one-ton mobile dump truck at the construction site, we cooperated with the second engineering area of ​​the Beijing No. 6 Construction Engineering Company and successfully produced the Harvest-35 and Z_3J-06 hydraulic loaders in succession. There is no basic chassis, no finished parts, and there are also difficulties in the source of major parts. It has not been promoted. Therefore, in June 1976 we continued to work on the development of the loader. After more than half a year’s efforts, we finally successfully prototyped the Z_3-04 hydraulic loader (Figure 1).
