The function of the driving device is to drive the concrete storage tank to rotate. It consists of a power take-off, a universal shaft, a hydraulic pump, a hydraulic motor, a control valve, a hydraulic oil tank and a cooling device.
If this part stops working due to failure, the concrete storage tank will not rotate, which will lead to the scrap of concrete in the vehicle, and even the whole tank of concrete will condense in the tank, resulting in the scrap of concrete mixer truck.
Therefore, whether the driving device is reliable or not is a problem that must be paid great attention to in use. In order to ensure that the driving device is intact and reliable, the following maintenance work shall be done:
a. The universal rotating part is the fault prone part. It should be filled with grease on time, checked for wear frequently, and repaired and replaced in time. The fleet shall have spare cardan shaft assembly to ensure that it can resume operation within several minutes in case of failure.
b. Ensure that the hydraulic oil is clean. The working environment of the concrete mixer truck is bad, so it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil shall be replaced regularly according to the requirements of the user manual. Once it is found that water or sediment is mixed in the hydraulic oil during inspection, it is necessary to shut down the machine immediately to clean the hydraulic system and replace the hydraulic oil.
c. Ensure that the hydraulic oil cooling device is effective. Clean the hydraulic oil radiator regularly to avoid the radiator being blocked by cement, check whether the electric fan of the radiator operates normally, and prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic oil is kept clean, there are not many faults in the hydraulic part, but the service life is different with different manufacturers.
