Because concrete will solidify into hard blocks in a short time, and it has a certain corrosive effect on steel and paint, it is necessary to wash the concrete adhered to the concrete tank and the inlet and outlet of the concrete tank after every use. These include:

A. Rinse the feed port with water before each loading to keep the feed port wet during loading;

B. At the same time to the car with the cleaning water tank filled with water;

C. After loading, rinse the feed port and clean the residual concrete near the feed port;

D. After unloading to the site, rinse the discharge tank, and then add 30-40 L of cleaning water to the concrete storage tank; Keep the concrete tank turning forward slowly when the vehicle is returning;

E. Remember to drain the sewage in the concrete tank before loading next time;

F. Clean the concrete tank and around the inlet and outlet thoroughly every day after work to ensure that there is no cement and concrete caked.

If the above work is not carried out seriously once, it will bring great trouble to the future work.
