When we use a small concrete mixer, we may encounter the phenomenon that the mixer jar is stuck, and then causes the phenomenon of rotation immobility. Then what should we do when we encounter this phenomenon? Let's take a look at the solution to it.

　　1、检查一下液压油是否漏光了(管子坏了换管子，密封件坏了换密封件）。

　　1. Check whether the hydraulic oil leaks completely (replace the pipe if the pipe is broken, and replace the seal if the seal is broken).

　　2、检查一下散热器风扇在转没有，液压油乳化变白没有，液压油温度超过90度，液压系统就没有压力，罐子就不转了。这种情况不要着急，用水冷却一下液压泵，液压马达，液压油温度下来，罐子就可以转动了。把料放出来，赶紧修理散热器或更换液压油。

　　2. Check whether the radiator fan is running, whether the hydraulic oil emulsion turns white, if the hydraulic oil temperature exceeds 90 degrees, the hydraulic system will not have pressure, and the tank will not rotate. Don't worry about this situation. Cool down the hydraulic pump, hydraulic motor and hydraulic oil with water. When the temperature of the hydraulic oil comes down, the tank can rotate. Put the material out and repair the radiator or change the hydraulic oil.
               

　　3、搅拌运输中没有注意，罐子停了，混凝土塌住了，罐子翻不过去。感觉有压力能转一点就可能是这种情况。

　　3. During mixing and transportation, the tank stopped, the concrete collapsed, and the tank could not turn over. If you feel pressure to turn a little bit, this may be the case.

　　4、动轴十字节损坏，断了。断了立即更换一根传动轴，传动轴用好的。

　　4. The cross section of moving shaft is damaged and broken. If it is broken, replace a transmission shaft immediately. The transmission shaft is in good condition.

　　5、压泵损坏了情况复杂一点，内泻严重。

　　5. The pressure pump is damaged. The situation is more complicated and the internal leakage is serious.

　　看完上述内容后，我们再遇到小型混凝土搅拌机罐子不转了的时候，不要惊慌，坚持一个原则，不要让混凝土凝结在罐子里，要把混凝土放出来，就可以从容处理搅拌机的故障。

　　After reading the above contents, we should not panic when the small concrete mixer pot does not rotate. We should adhere to the principle that the concrete should not be condensed in the tank. If we want to release the concrete, we can handle the failure of the mixer calmly.
