Cleaning Small Concrete Mixer Trucks

Since concrete hardens quickly and is corrosive to steel and paint, thoroughly cleaning concrete residue from the mixing drum and the loading/unloading ports after each use is a crucial part of daily maintenance. The required procedures include:
1. Rinsing the loading port with water before each loading operation to keep it moist;
2. Filling the vehicle's onboard water tank while loading;
3. Rinsing the loading port after loading to remove any residual concrete;
4. Rinsing the discharge chute after unloading at the job site, then adding 30–40 liters of water into the mixing drum and keeping the drum rotating slowly in the forward direction during the return trip;
5. Draining the wastewater from the mixing drum before the next loading operation;
6. Thoroughly cleaning the mixing drum and the areas around the loading and unloading ports at the end of the workday to ensure no cement or hardened concrete remains attached.
Failure to perform any of these steps diligently can lead to significant problems for future operations.
