Concrete Mixer Truck, full name concrete mixer truck, is a special truck used to transport concrete for construction.It is composed of automobile chassis, mixing drum, transmission system, water supply device, full-power power take-off, front and rear support of the mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, the domestic mixer trucks with a volume of 3m³-8m³ adopt the four major domestic products, and most of the four components with a volume above 8m³ are imported components.
Composition of mixer truck: second-class chassis, transmission system, 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 and the reducer are connected and installed on the front of the rack, and the rear end is supported by the two supporting wheels installed on the back of the rack through the raceway.
It is mainly composed of a mixing drum and its auxiliary supporting parts. The mixing drum is a container for loading concrete. It is made of high-quality wear-resistant thin steel plate. In order to be able to automatically load and unload concrete, its inner wall is welded with spiral blades with special shapes. When rotating, the concrete moves in the spiral direction of the blade, and is mixed and stirred during the continuous lifting and turning process. During the feeding and transportation process, the mixing drum rotates forward, and the concrete moves inward along the blade. When discharging, the mixing drum reverses and the concrete is discharged outward along the blade. The rotation of the mixing drum is guaranteed by the hydraulic drive. The loading capacity is 3~6 cubic meters. The concrete mixer truck generally adopts a Car engine to drive a hydraulic pump through a power output shaft, and then a high-pressure oil drives a hydraulic motor to drive a mixing drum. If the loading capacity is 9-12 cubic meters, a vehicle-mounted auxiliary diesel engine drives the hydraulic pump to drive the hydraulic motor. The blade is the main component of the mixing device. Damage or severe wear will cause uneven mixing of the concrete. In addition, if the angle of the blade is not designed properly, it will also cause segregation of the concrete.

The function of the driving device is to drive the rotation of the concrete storage tank, which is composed of a power take-off, a universal shaft, a hydraulic pump, a hydraulic motor, a control valve, a hydraulic oil tank and a cooling device. If this part stops working due to a malfunction, the concrete storage tank will not be able to rotate, which will cause the concrete in the vehicle to be scrapped, and even the entire tank of concrete will be condensed in the tank, causing the concrete mixer truck to be scrapped. Therefore, whether the driving device is reliable is a problem that must be highly valued in use. In order to ensure that the drive device is intact and reliable, the following maintenance work should be done:
a. The universal rotating part is a part with frequent failures, grease should be added on time, and the wear condition should be checked frequently, and repaired and replaced in time. The team should have a spare universal joint assembly to ensure that if a failure occurs, it can resume work within tens of minutes.
b. Ensure that the hydraulic oil is clean. The working environment of the concrete mixer truck is bad, so it is necessary to prevent the sewage cement from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the user manual. Once it is found that water or sediment is mixed in the hydraulic oil during the inspection, it is necessary to immediately shut down to clean the hydraulic system and replace the hydraulic oil.
c. Ensure that the hydraulic oil cooling device is effective. Regularly clean the hydraulic oil radiator to avoid the radiator being blocked by cement. Check whether the radiator electric fan is running normally to prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic parts are kept clean, there are not many failures in general; but the service life is different for different manufacturers.
