A concrete mixer truck is a specialized truck used to transport concrete for construction purposes. Due to its appearance, it is often referred to as a snail truck. These types of trucks are equipped with cylindrical mixing drums to transport the mixed concrete. During transportation, the mixing drum will always rotate to ensure that the concrete being transported does not solidify. After transporting the concrete, the inside of the mixing drum is usually rinsed with water to prevent hardened concrete from occupying space and reducing the volume of the mixing drum. Its specialized mechanisms mainly include power take-off, front and rear supports of the mixing drum, reducer, hydraulic system, mixing drum, control mechanism, cleaning system, etc
