在毛主席革命路线指引下,我厂职工以阶级斗争为纲,高举“鞍钢宪法”的光辉旗帜,在上级领导的关怀和兄弟单位的大力支持下,与天津工程机械研究所组成三结合小组,研制出 Z4H2型回转武装载机(见36页)。为我国工程机械增添了一个新品种。该机以装卸沙、煤、碎石等松散物料为主,换装加长臂及铲斗可用来挖沟(见封3)。工作装置可左、右回转90°。适用于国防、水电、矿山、建筑等中小型土方工程施工,特别适用于在狭窄场地配合车辆装车。遵照毛主席关于“精心设计,精心施工”的教导,我们对该产品进行了三轮样机试制和 Under the guidance of Chairman Mao’s revolutionary line, the workers of our factory take the class struggle as the key, holding high the banner of “Anshan Iron and Steel Constitution”. With the support of the leaders at higher levels and the strong support of the fraternal units, we form a three-combination group with the Tianjin Institute of Construction Machinery. Z4H2 rotary armed carrier was developed (see page 36). Added a new breed for our country’s engineering machinery. The machine mainly consists of loose materials such as loading and unloading of sand, coal, and gravel, and the long arm and bucket can be used to dig trenches (see cover 3). The working device can be turned 90° left and right. It is suitable for the construction of small and medium-sized earthworks such as national defense, hydropower, mining and construction, and is especially suitable for loading vehicles on narrow sites. In accordance with Chairman Mao’s guidance on “meticulous design and careful construction”, we conducted a trial of three prototypes on this product and
