A concrete mixer truck is a specialized vehicle used to transport concrete for construction purposes; Due to its appearance, it is often referred to as a snail cart,
These types of trucks are equipped with cylindrical mixing drums to carry the mixed concrete.
During transportation, the mixing drum will always be kept rotating to ensure that the concrete carried will not solidify.
After transporting concrete, it is usually necessary to flush the inside of the mixing drum with water to prevent hardened concrete from occupying space and reducing the volume of the mixing drum.
