Second, what are the implications of concrete mixer truck overloading concrete? 
Below 9 square concrete mixer truck over fitted concrete, the car in the process of climbing would leak spill; for 12 square concrete mixer truck over loading concrete, stirring delamination, concrete sand ratio on the low side, gravel particle size is too large, to the site pumping more stones. 

Third, how many years driving will new concrete mixer truck easily appear 
Loading dry material is generally five years, seven years is generally wet material, prone to problems for common concrete mixer truck is in three years later. The fault of concrete mixer truck has a great relationship with personal maintenance and the manufacture. 

Fourth, what should be done if concrete concreting in the concrete mixer truck? 
After the concrete hard setted, the main component is dicalcium silicate, tricalcium silicate. Theoretically, hydrochloric acid can react to lift its solid shape. But in fact difficult to operate because of the mixer spout is small, difficult to control the amount of hydrochloric acid and hydrochloric acid can also occur with the mixer tank. This situation arose in practice, often by cutting gas cutting or welding tank, then solidified concrete crushing machine. 

Fifth, what is the mean of tops-configuration of concrete mixer truck? 
Concrete mixer truck tops refers mixer truck everything except fender chassis, including stirred tank and seat, out of the hopper, hydraulic systems and gear units, tanks and piping, operating link mechanism.
