The general capacity of concrete mixer is 8 cubic meters.

Concrete mixer truck is a special truck used to transport concrete for construction, also known as snail truck. The concrete mixer truck is equipped with a cylindrical mixing tank to carry the mixed concrete. During the transportation, it will rotate all the time to ensure that the concrete will not solidify. After the transportation, it is necessary to flush the inside of the mixing tank with water to prevent the hardened concrete from occupying the space capacity and making the volume of the mixing tank smaller and smaller.
