The driving device is used to drive the concrete storage tank to rotate. It is composed of power takeoff, universal shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device.
If this part stops working due to failure, the concrete storage tank will not rotate, which will lead to the scrapping of the concrete in the vehicle, and even the whole tank of concrete will condense in the tank, resulting in the scrapping of the concrete mixing 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 the integrity and reliability of the driving device, the following maintenance work shall be done:
a. The universal rotating part is a fault prone part, so the lubricating grease shall be filled on time, the wear shall be checked frequently, and the parts shall be repaired and replaced in time. The fleet shall have spare cardan shaft assembly to ensure that it can resume operation within tens of minutes in case of failure.
b. Ensure that the hydraulic oil is clean. The working environment of concrete mixer truck is bad, so it is necessary to prevent dirty cement sand from entering the hydraulic system. The hydraulic oil shall be replaced regularly according to the requirements of the operation manual. Once water or sediment is found in the hydraulic oil during inspection, stop 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 prevent the radiator from being blocked by cement. Check whether the electric fan of the radiator operates normally to prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic part keeps the hydraulic oil clean, there are few general faults; However, different manufacturers have different service life.
