As for the failure causes of the working device of the small loader and how to deal with it, the small loader is a kind of earthwork construction machinery widely used in highway, railway, hydropower, construction, port, mine and other construction projects. It can also be used for bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. In the construction of roads, especially in high-grade highways, small loaders are widely used in the filling and excavation of subgrade works, the aggregate and loading of asphalt mixtures and cement concrete yards, etc.

装载机的工作装置在装配和使用过程中，主要存在以下问题：(1)装配困难。部件装不上或装配后铰接处转动不灵活，此时需要拆卸下来进行火焰校正或到胎具上校正。有时几个部件虽然能够装配起来，但由于零件公差超标，易造成局部磨损和干涉，留下隐患。(2)整机装配出厂后使用一段时间出现质量事故。如摇臂弯曲扭断、动臂变形、横梁开焊、铲斗拉斜撕裂、液压缸拉伤漏油及活塞杆弯曲等。

During the assembly and use of the working device of the loader, there are mainly the following problems: (1) assembly difficulties. If the parts cannot be installed or the hinge joint cannot rotate flexibly after assembly, it needs to be removed for flame correction or correction on the mold. Sometimes several parts can be assembled, but due to the excessive tolerance of parts, it is easy to cause local wear and interference, leaving hidden dangers. (2) Quality accidents occurred after the whole machine was assembled and used for a period of time. For example, the rocker arm is bent and broken, the boom is deformed, the beam is welded, the bucket is tilted and torn, the hydraulic cylinder is strained and leaks oil, and the piston rod is bent.

主要原因：工作装置在制造过程中，由于焊接精度不良，造成装配困难，使机器工作中各零件受力不正常，引起磨损及破坏；液压缸不合格也是造成工作装置装配困难和破坏的重要因素。装载机工作装置损坏一般集中在前车架、动臂和液压缸等部件上。

Main reasons: during the manufacturing process of the working device, due to poor welding accuracy, it is difficult to assemble, so that the stress of each part of the machine is abnormal, causing wear and damage; The unqualified hydraulic cylinder is also an important factor causing the assembly difficulty and damage of the working device. The damage of loader working device is generally concentrated on the front frame, boom, hydraulic cylinder and other components.

措施：对焊接工装进行改进或重新设计；对各部件的焊接和加工质量严格控制，遵守各种工艺和操作规程；增强液压缸的检测工作，对动臂、转斗液压缸等进行严格的质量控制。

Solution: improve or redesign the welding tooling; Strictly control the welding and processing quality of all components, and abide by various processes and operating procedures; Strengthen the inspection of hydraulic cylinder and strictly control the quality of boom and bucket hydraulic cylinder.
