A mixer truck is a special truck used to transport concrete for construction; because of its shape, it is also often called a snail truck and an olive truck. These 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 carried concrete will not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the remaining concrete from hardening and occupying space, so that the volume of the mixing drum becomes smaller and smaller.
The concrete mixer truck is composed of a truck chassis and a special device for concrete mixing and transportation. The chassis of concrete mixer trucks produced in China mostly adopts the Class II general chassis provided by the vehicle manufacturer. Its special mechanism mainly includes power take-off, front and rear supports of mixing cylinder, reducer, hydraulic system, mixing cylinder, operating mechanism, cleaning system, etc. The working principle is to take out the power of the automobile chassis through the power take-off device, drive the variable pump of the hydraulic system, convert the mechanical energy into hydraulic energy, and transmit it to the quantitative motor. The motor drives the reducer, and the reducer drives the mixing device to mix the concrete.
