1. The mixer itself fails.
a. First of all, we will think about whether there is something wrong with the engine. If the engine is booming all the time, we should eliminate the engine problem and check the working condition of the oil pump to see whether the transmission shaft is damaged or broken. If it is broken, replace it immediately.
b. If the transmission shaft is good and the oil pump is working normally, check the hydraulic oil: if the hydraulic oil leaks, it is a problem with the pipes and seals. Replace the pipes and seals.
c. Check whether the radiator fan is running. If the hydraulic oil turns white and emulsified, and the temperature of the hydraulic oil exceeds 90 degrees, there will be no pressure in the hydraulic system and the mixing tank will not rotate naturally. Solution: cool the hydraulic pump and motor with water, the temperature of the hydraulic oil drops, and the mixing tank can rotate. This is the solution in an emergency, not a permanent cure. After the concrete is put out, repair the radiator or replace the hydraulic oil to fundamentally solve the problem.
d. When the hydraulic pump is damaged, the emergency treatment method is to use the hydraulic pump of other concrete mixer truck to drive the hydraulic motor to rotate the mixing tank, discharge the concrete, and then repair or replace the hydraulic pump.
e. If the hydraulic motor is damaged or the reducer is damaged, the emergency device can not be used. The inspection cover on the mixing tank can be opened to discharge the concrete, and then the hydraulic motor and reducer can be repaired.
2. All these are the problems of the mixer itself and the concrete.
During transportation, the concrete collapse causes the mixing tank to stop rotating. Don't panic at this time. I'll teach you the solution.
If the access hole is above the mixing tank, the tower crane and winch shall be used to rotate the inspection cover of the tank body to the lower part to release the concrete; if the tank body is stuck and can not rotate, a 50 cm square hole can be opened under the tank body by gas cutting (pay attention to avoid the rotating blades in the tank, the cut tank wall must be retained, and the repair is fast, convenient and beautiful) to release the concrete.
