concrete mixer truck It is composed of automobile chassis, mixing drum, transmission system, water supply device, full-power power take-off, front and rear brackets of mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, domestically-made mixer trucks with a tank volume of 3m³-8m³ use four domestically-made parts, and most of the four major parts used for those with a volume of over 8m³ are imported parts.

concrete Mixer truck composition: second-class chassis, drive train, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, human ladder and other parts. The front end of the mixing tank is connected with the reducer and installed on the front of the frame, and the rear end is supported by two supporting wheels installed on the back of the frame through a raceway.

The power is output by the full-power power take-off of the second-class chassis. The power is transmitted to the hydraulic pump through the transmission shaft. The hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the tubing. The hydraulic motor converts the hydraulic energy into kinetic energy and transmits it through the reducer. For the mixing tank, by adjusting the angle of the servo handle of the hydraulic pump (double-acting variable), the positive and negative rotation and speed of the mixing tank can be realized to realize concrete loading, mixing, stirring, and discharging operations.
