The general situation is as follows:
1、 Check whether the hydraulic oil leaks (replace the pipe if the pipe is broken, and replace the seal if the seal is broken)!
2、 Check if the radiator fan is running, if the hydraulic oil is emulsified and turned white, if the temperature of the hydraulic oil exceeds 90 ℃, there will be no pressure in the hydraulic system, and the tank will not turn（ In this case, don't worry. Use water to cool the hydraulic pump and motor. When the temperature of the hydraulic oil comes down, the can can turn. Let the material out, repair the radiator or change the hydraulic oil
3、 I didn't pay attention during transportation. The jar stopped! The concrete has collapsed and the jar can't turn over（ If you feel pressure, you can turn a little bit. This may be the case.)
4、 Engine failure (impossible, boom, boom, boom
5、 The cross joint of transmission shaft is damaged and broken (a) replace a transmission shaft immediately if it is broken; B) transmission shaft (good);
6、 The hydraulic pump is damaged (the situation is a little more complicated, the internal leakage is serious, and other damage is caused);
If the above six situations occur, and the concrete does not coagulate, and the hydraulic motor and reducer have no fault, you can use the emergency device, and use the hydraulic pump of another mixer to drive the hydraulic motor to rotate the tank, release the concrete, and then repair it! How to use the emergency device and precautions, we will talk about it again in the future!!
7、 The hydraulic motor is damaged!
8、 The reducer is out of order!!
Seven, eight two cases, can not use the emergency device! The inspection cover on the tank can be opened to release the concrete.
What to do if the cover is above the tank?? The tower crane and winch can be used to rotate the inspection cover of the tank to the bottom to release the concrete;
What if the jar gets stuck and doesn't rotate? A 50 cm square hole can be cut 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) to release the concrete.
The jar doesn't work. Don't panic! Don't rush!
Adhere to a principle, do not let the concrete set in the tank, cleaning up the concrete set in the mixing tank is time-consuming and expensive! Concrete out, you can calmly deal with the mixer's fault!!
