1、 As a concrete mixer, the concrete mixing tank should be maintained first, and the new concrete mixer should be used to fasten the tank support and the chassis frame of the vehicle in real time. After each concrete transportation and into the cleaning tank, it is necessary to know that the concrete is easy to bond with steel.
2、 The uniformity of discharging is one of the important indexes of the function of concrete mixer truck, which directly affects the construction quality. When transporting concrete, the rotation speed of mixing drum should be controlled at 2 ~ 5R / min. if the transportation interval is long and the slump of concrete is large, the mixing drum should be moved 5 ~ 10 times before discharging, so that the concrete inside can be fully mixed, so that the uniformity of discharge will be greatly improved. If the concrete loses water on the way, water should be added to the construction site for mediation and full mixing. Although this kind of environment should only be stopped, the quality of concrete will not be guaranteed. Some users do not pay attention to control the speed in the transportation process, too fast will increase the fuel consumption, too small will cause concrete segregation. Therefore, the rotation speed of mixing drum should be controlled strictly according to the requirements, so as to improve the quality of concrete transportation.
3、 The maximum limit of concrete can not be higher than the maximum volume of the tank, because the concrete strength grade is different, its density is also different, high strength concrete is generally of high density, the same volume, too much loading is bad for cars. The capacity, quality and slump of concrete to be transported shall be in accordance with the provisions in the vehicle operation manual, and lubricating oil shall be added in real time.
4、 For the concrete mixer truck which has been parked in the open air, the mixing drum should be rotated to discharge the water in the cement tank before loading, so as to ensure the quality of concrete transported.
5、 When driving on the road, the unloading chute is lowered to the lowest position and turned to the vertical part of the vehicle body. The unloading chute is locked on the frame with the locking device to prevent it from shaking due to instability, causing injury and disturbance and affecting the operation of other vehicles. If the ladder condition is not good, the tank shaft of the tank car will be damaged.
6、 Before unloading, if the water evaporation and slump are found to be low, it can not be full. When required by the user, water can be added into the mixing drum properly, and then the material can be discharged after 30 rotations at the speed of 6 ~ 10R / min according to the feeding deviation.
7、 In the process of transporting concrete by concrete mixer truck, the mixing drum shall not contain moving motion, so as to avoid concrete segregation.
