WX2—75悬挂履带挖掘机是我所研制的。一九七六年十二月,沈阳市农机工业局组织了该机的鉴定会。会议结论:同意WX2—75悬挂履带挖掘机(图1)定型和批量生产,产品可提供出口。挖掘机的动力是东方红—75拖拉机。挖掘机由挖掘装置、液压系统、回转机构、悬挂装置、操纵机构、配重铁等部分组成(图2)。挖掘装置由动臂、斗柄、铲斗和相应的油缸组成。采用反铲作业。由于各构件的杆长比和各铰点位置的确定比较合理,因此能够满足各种施工中的使用要求,作业范围比较大,机构比较紧凑,具有足够的挖掘力和提升力。动臂和斗柄采用封闭的箱形结构,有 WX2-75 suspension track excavator is what I developed. In December 1976, Shenyang Agricultural Machinery Bureau organized the appraisal of the aircraft. Conference Conclusion: WX2-75 agreed suspension crawler excavator (Figure 1) stereotypes and mass production, the product can provide exports. Excavator power is red Oriental -75 tractor. Excavator excavator, hydraulic system, slewing gear, suspension, control mechanism, iron and other components (Figure 2). Excavation device consists of boom, bucket handle, bucket and the corresponding cylinder composition. Backhoe work. As each component’s rod length ratio and each hinge point position is more reasonable, it can meet the requirements of various kinds of construction. The working range is relatively large, the mechanism is compact, and has sufficient digging force and lifting force. Boom and bucket handle with a closed box structure, there
