Maintenance procedure when cleaning the concrete mixer truck

Concrete mixer trucks or mixer trucks are dedicated trucks used to transport ready-mixed concrete for construction; due to its shape, they are often called snails. A cylindrical mixer drum is mounted on the truck to carry the mixed concrete and the mixer drum is always kept rotating during transportation to ensure that the concrete carried does not freeze. After transporting the concrete, the inside of the mixing drum is usually rinsed with water to prevent the hardened concrete from occupying the space.

Cleaning concrete tanks (mixing drums) and inlet and outlet ports Because concrete will solidify into hard blocks in a short time and have certain corrosivity to steel and paint, each time the concrete tank is used, it is washed and adhered to concrete storage tanks. The concrete on the tank and inlet and outlet is a work that must be carried out carefully for daily maintenance. These include:

a. Rinse the feed inlet with water before each charge to keep the feed inlet moist while charging;

b. Fill the cleaning water tank that comes with the vehicle while filling;

c. After filling, wash the inlet and clean the remaining concrete near the inlet;

d. After unloading at the construction site, flush the discharge chute, and then add 30 to 40L of cleaning water to the concrete tank; keep the concrete tank slowly turning at a slow speed while the vehicle is returning;

e. Remember to drain the concrete tank before loading the next time;

f. Clean the concrete storage tank and the surrounding of the material inlet and outlet thoroughly during the daily work, ensuring that there is no cement and concrete agglomeration.

If these tasks are not carried out carefully once, they will cause great trouble for future work.
