standard mixing truck

Mixing truck national standard has been implemented for many years, it is the determination of the parameters is basically carried out in accordance with international common practice equivalent formulation, some projects were also in accordance with national conditions improve.
However, the reality of the past 10 years shows that the concrete mixer truck is not effective implementation of national standards most of construction machinery, Concrete mixing plants quality and safety of the transportation process are not properly guaranteed. Dozens of manufacturers produce mixer truck, concrete is not able to guarantee deliveries of segregation, whether generated or excessive bleeding detection and stir yet defined, concrete projects can guarantee the quality, but also the lack of final inspection. The durability of concrete indicators are able to achieve it is worrying.
Country more than two hundred thousand units mixer truck in the safe operation aspects, more serious. Driving stability greatly affected, because the increase in the total mass of the heavy travel speed is constant, a geometric inertia force multiplier, making the car's steering and braking force seriously out of control, urban construction vehicles in concrete mixer machine , mixer accounted for first place, many drivers become taken advantage of this equipment and the victim. Root cause lies in the so-called manufacturers to meet the user's requirements, and seek maximum sales resulting design is not standardized. National Standards Authority of concrete machinery Standards Committee Chairman Ren Longguo kin emotionally said: "Almost 100% of the enterprise product standard will not really law refractory masses" are seeking ways of governance.
