The first consideration in the selection of concrete mixer trucks is that the vehicle must be very reliable,and the probability of failure of key parts such as the engine and the transmission-drive device should be as low as possible.Because the concrete is loaded into the car,it is required to be unloaded on the working surface within 2 hours or less,and it must be continuously stirred during this period.If it cannot be transported to the construction site within the specified time or the mixing is stopped for various reasons,the concrete in the truck will be scrapped.This puts forward strict requirements on the reliability of the mixer truck,and it is absolutely not allowed to stop the mixer truck when it is working.

　　The load should be appropriate

　　Theoretically speaking,the larger the loading capacity of the transportation vehicle,the higher the transportation efficiency,but this will also lead to a linear increase in the purchase cost of the vehicle and a decrease in the passability.The concrete mixer truck with a loading capacity of 8~9m and an 8x4 chassis should have a loading capacity of 6~7m.,6x4 chassis price

　　The price is 30%~40%expensive;at the same time,the construction site is generally small and the temporary construction road conditions are very poor.The problem of inconvenience of large vehicles,especially semi-trailers,must be fully considered.Therefore,when determining the loading capacity of the vehicle,all factors must be comprehensively considered,and one cannot ignore the other.
