北京市第一建筑工程公司机械队机修车间四班工人高举“鞍钢宪法”的光辉旗帜,为发展建筑施工小动力装运机械,组成了“三结合”研制小组,“自力更生”,“跟苦奋斗”,在半年内试制成功一台W-300型液压蛙式铲运车(图1)。W-300型铲车除发动机外,自制率达到百分之九十八。 W-300型液压铲车的工作机构一门架升降行程为2米。其动作是:液压油缸顶升(回
The four class workers of the mechanical engineering workshop of Beijing No.1 Construction Engineering Company held high the banner of “Anshan Iron and Steel Constitution”. In order to develop small-scale power loading and transportation machinery for building construction, a “three-in-one” development team was formed, “self-reliant” and “fighting hard”. In a six-month trial, a W-300 hydraulic frog-type shovel was successfully manufactured (Figure 1). In addition to the engine, the W-300 shovel has a self-made rate of 98%. The working mechanism of the W-300 hydraulic forklift has a mast stroke of 2 meters. The action is: hydraulic cylinder jacking (back
