Concrete Trucks consists of a car chassis and concrete mixing equipment. China's production of concrete mixer truck chassis used by the vehicle manufacturers to provide more than two types of general chassis. Its special institutions include power take-off, mixing cylinder front and rear bracket, reducer, hydraulic system, mixing tube, control mechanism, cleaning system. The working principle is that the power of the car chassis is removed by the take-up device and the variable pump of the hydraulic system is driven. The mechanical energy can be converted into hydraulic energy to the quantitative motor. The motor drives the reducer again and drives the agitator by the reducer.
