Why doesn't the small mixer turn? The general situation is:

一、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 out (replace the pipe if the pipe is broken, and replace the seal if the seal is broken)!

二、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 is emulsified and white, and if the hydraulic oil temperature exceeds 90 degrees, there will be no pressure in the hydraulic system and the tank will not run! (in this case, don't worry. Use water to cool the hydraulic pump, hydraulic motor and hydraulic oil. When the temperature of the hydraulic oil comes down, the tank can rotate. Release the material and repair the radiator or replace the hydraulic oil quickly!)

三、运输途中没有注意，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、 I didn't pay attention during the transportation. The jar stopped! The concrete collapsed and the jar couldn't turn over! (this may be the case if you feel pressure and can turn a little)

四、发动机故障(不可能哦，轰隆隆响起在!!)

4、 Engine failure (impossible, rumbling!!)

五、传动轴十字节损坏，断了(a断了立即更换一根传动轴;b传动轴好的);

5、 If the transmission shaft of a cross shaft is broken, replace it immediately;

六、液压泵损坏了(情况复杂一点，内泻严重，其他损坏);

6、 The hydraulic pump is damaged (the situation is a little complicated, the internal leakage is serious, and other damage);

以上六种情况出现，且混凝土没有凝结，液压马达、减速机没有故障，可以使用应急装置，用另一辆搅拌车的液压泵带动液压马达转动罐子，将混凝土放出，再检修!

If the above six situations occur, and the concrete does not set, and the hydraulic motor and reducer do not fail, you can use the emergency device, use the hydraulic pump of another mixer to drive the hydraulic motor to rotate the tank, discharge the concrete, and then repair!

七、液压马达损坏了!

7、 The hydraulic motor is damaged!

八、减速机坏了!!

8、 The reducer is broken!!

这两种情况出现，不能使用应急装置!可以将罐体上的检查盖打开将混凝土放出。

In these two cases, the emergency device cannot be used! The inspection cover on the tank can be opened to discharge the concrete.

对不起，检查盖在罐体上方怎么办?可以用塔机、卷扬机将罐体检查盖旋转到下方，将混凝土放出;

Sorry, what if the inspection cover is above the can body? The tower crane and winch can be used to rotate the tank inspection cover to the bottom to release the concrete;

对不起，罐子卡住了旋转不动怎么办?可以在罐体侧下方用气割开一个50厘米见方的孔(注意避开罐里的螺旋叶片，割下的罐壁一定保留，修复起来迅速、方便而且美观)，将混凝土放出。

Sorry, the jar is stuck. What if it doesn't rotate? A 50 cm square hole can be cut with gas under the side of the tank (pay attention to avoid the spiral blade in the tank, the cut tank wall must be retained, and the repair is fast, convenient and beautiful), and the concrete can be discharged.

坚持一个原则，不要让混凝土凝结在罐子里，清理凝固在搅拌罐里的混凝土是又费时间、又费钱的事!混凝土放出来，你可以从容处理搅拌车的故障!!

Adhere to a principle, do not let the concrete set in the jar. Cleaning up the concrete set in the mixing jar is a time-consuming and expensive thing! When the concrete is released, you can calmly deal with the failure of the mixer truck!!
