6x4 Sinotruk Howo Concrete mixer truck

6x4 Sinotruk Howo Concrete mixer truck is composed of an automobile chassis and a special device for concrete mixer transportation. Most of the chassis of concrete mixer trucks produced in my country adopt the second-class universal chassis provided by the vehicle manufacturers. Its special mechanism mainly includes power take-off, front and rear brackets of mixing drum, reducer, hydraulic system, mixing drum, control mechanism, cleaning system, etc. The working principle is that the power of the chassis of the car is taken out through the power take-off device, and the variable pump of the hydraulic system is driven to convert the mechanical energy into hydraulic energy to the quantitative motor. The motor then drives the reducer, which drives the mixing device to carry out the concrete Stir.

According to the moisture content of the concrete transported by the concrete mixer, there are three types of mixer trucks: wet type, dry type and semi-dry type.

Wet material concrete mixer trucks are mostly used in China. It can load concrete produced by the mixing plant (station) or aggregates (sand, stones), cement and water mixed in proportions. During the transportation process, the wet material is slowly Mixing to prevent the initial setting and segregation of concrete during transportation. However, the time from production to pouring of concrete should generally not exceed 1.5h to avoid concrete setting. Therefore, in the case of longer distance transportation, dry and semi-dry material mixing trucks are required for transportation.

The dry-type mixer truck can directly load dry aggregate and cement into the mixing drum of the truck according to the ratio. During the transportation process, the dry material in the drum is mixed. When the vehicle is about to reach the construction site or add water to the construction site Complete the mixing of concrete.

The aggregate and cement in the concrete transported by the semi-dry mixer truck are also formulated according to the ratio and contain a certain amount of water, but the water content does not meet the pouring requirements. The vehicle will reach the construction site or the construction site Add water and stir.
