Mixer Truck
Concrete mixer truck is a special truck used to transport concrete for construction; because of its shape, it is often referred to as a field snail truck. These trucks are equipped with cylindrical stirrer to carry mixed concrete. In the course of transportation, the mixing drum will always be rotated to ensure that the concrete carried will not solidify. After the concrete is transported, the inner part of the mixing drum is usually flushed with water to prevent the hardening of the concrete from occupying space, so that the volume of the mixing drum becomes smaller and smaller.
