The Maintenance of Concrete Mixing Truck

2016-12-16 12:03:11


Concrete mixer truck as a transport vehicle, in the maintenance and repair must be in accordance with the Ministry of Communications, Decree No. 13 of 1990, the implementation of "regular testing, mandatory maintenance, as appropriate repair" maintenance and repair system. In this premise, combined with concrete mixing truck, the actual situation, good maintenance and repair. In the daily maintenance, the concrete mixer truck in addition to the conventional car engine, chassis and other parts of the maintenance, but also must do the following maintenance work.
Cleaning concrete tank (mixing tube) and the inlet and outlet
As the concrete will be solidified into lumps in a short time, and the steel and paint a certain degree of corrosion, so each time the use of concrete storage tank, clean and adhere to the concrete storage tank and out of the mouth of the concrete is a daily maintenance must Conscientious work. These include:
A. The feed inlet is rinsed with water each time before filling to keep the feed port wet during charging;
B. In the loading at the same time to the car comes with cleaning water tank filled with water;
C. Rinse the feed inlet after loading, and clean the residual concrete near the feed inlet;
D. To the site after discharge, flushing the trough, and then to the concrete tank plus cleaning water 30-40 L; in the vehicle return to maintain the positive slow rotation of the concrete tank;
E. Remember to let go of the waste water from the concrete tank before the next filling;
F. Wash the concrete tank every day and wash the concrete around the entrance and exit, to ensure non-sticky cement and concrete agglomeration. The above work as long as one does not seriously, it will bring great trouble to the future work.
Maintain the drive
The role of the drive device is to drive concrete tank rotation, which by the power take-off, universal axis, hydraulic pumps, hydraulic motors, control valves, hydraulic tanks and cooling devices. If this part of the work to stop due to failure, concrete storage tank will not be able to rotate, which will lead to scrap concrete in the car, and even make the whole tank of concrete condensation in the tank, causing the concrete mixing truck scrapped. Therefore, whether the drive is reliable is a problem that must be paid close attention to in use. In order to ensure the drive is intact and reliable, should do the following maintenance work:
A. Universal rotary part is a fault-prone parts, should be filled with grease, and often check the wear and tear, timely repair and replacement. The team should have a spare shaft assembly to ensure that in the event of failure in dozens of minutes to resume work.
B. Ensure that the hydraulic oil is clean. Concrete mixer truck working environment is harsh, we must prevent the sewage sediment into the hydraulic system. The hydraulic oil should be changed periodically according to the instruction manual. Once the inspection found in the hydraulic oil mixed with water or sediment, we must immediately stop cleaning the hydraulic system, replace the hydraulic oil. C. Ensure that the hydraulic oil cooling device is effective. To regularly clean up the hydraulic oil radiator, to avoid the radiator was cement clogged, check the radiator electric fan is running, to prevent the hydraulic oil temperature exceeded. Hydraulic part of the hydraulic oil as long as the clean, the general failure is not much; but the different manufacturers, life is not the same.
