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 conveying quality and safety of the transportation process are not properly guaranteed. stationary concrete batching plant 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.
Concrete mixing plants 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 traffic accidents , 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.
