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 be able to rotate, which will cause the concrete in the vehicle to be scrapped, and even cause the entire tank of concrete to condense in the tank, causing the concrete mixer truck to be scrapped. Therefore, the reliability of the driving device is an issue that must be highly valued in use. In order to ensure the integrity and reliability of the drive device, the following maintenance work should be done:
a. The universal rotating part is a fault-prone part. Grease should be added on time, and the wear and tear should be checked frequently, and repaired and replaced in time. Teams should have spare universal joint shaft assemblies to ensure that they can resume work within tens of minutes in the event of a failure.
b. Ensure that the hydraulic oil is clean. The working environment of the concrete mixer truck is harsh, and it is necessary to prevent sewage and sediment from entering the hydraulic system. Hydraulic oil should be replaced regularly according to the instruction manual. Once the hydraulic oil is found to be mixed with water or sediment during the inspection, it is necessary to immediately stop the hydraulic system to clean the hydraulic system and replace the hydraulic oil.
c. Ensure that the hydraulic oil cooling device is effective. It is necessary to clean the hydraulic oil radiator regularly to avoid the radiator being blocked by cement, check whether the electric fan of the radiator is running normally, and prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic oil is kept clean, there are generally not many failures; but different manufacturers have different service lives.
