1、 As a concrete mixer, first of all, it is necessary to maintain the box of the concrete mixer, and use a new concrete mixer to fix the box bracket near the chassis frame in real time. Every time after transporting the concrete and entering the cleaning tank, it is necessary to know that the concrete is easy to bond with the reinforcement.

二、出料的对称性是混凝土搅拌车的重要指标之一，直接影响施工质量。运输混凝土时，搅拌筒的转速应控制在2~5r/min。当混凝土坍落度较大，运输间隔较长时，出料前应快速移动搅拌筒5~10次，使内部混凝土充分搅拌，大大提高出料的对称性。

2、 Discharging symmetry is one of the important indexes of concrete mixer, which directly affects the construction quality. When transporting concrete, the rotation speed of mixing drum should be controlled at 2 ~ 5R / min. When the concrete slump is large and the transportation interval is long, the mixing drum should be moved quickly for 5 ~ 10 times before discharging, so that the internal concrete can be fully mixed and the symmetry of discharging can be greatly improved.

如果混凝过程中失水，应在施工现场加水进行调解和充分搅拌。虽然这种环境应该停止，混凝土的质量将无法保证。有些用户在运输过程中不注意速度控制，过快会增加油耗，过小会造成混凝土离析。因此，搅拌筒的转速应严格按照资质要求进行控制，以提高混凝土的运输质量。

In case of water loss during coagulation, water should be added to the construction site for mediation and full mixing. Although this environment should stop, the quality of concrete will not be guaranteed. Some users do not pay attention to speed control during transportation, too fast will increase fuel consumption, too small will cause concrete segregation. Therefore, the rotation speed of the mixing drum should be strictly controlled according to the qualification requirements, so as to improve the transportation quality of concrete.

三、混凝土的至高不能高于储罐的至大容积，因为混凝土的密度因强度等级的不同而不同。高强混凝土一般具有较高的密度，相同的体积对汽车不利。输送混凝土的能力、质量和坍落度应符合车辆操作手册的规定，并应实时加注润滑油。

3、 The maximum height of concrete should not be higher than the maximum volume of storage tank, because the density of concrete varies with the strength grade. High strength concrete generally has high density, and the same volume is not good for cars. The capacity, quality and slump of concrete conveying shall comply with the provisions of vehicle operation manual, and lubricating oil shall be added in real time.

四、混凝土搅拌车停在露天时，装载前应先将搅拌筒卸去旋转，把水泥罐中的水放掉，以保证运输混凝土的质量。

4、 When the concrete mixer truck is parked in the open air, the mixing drum should be removed and rotated before loading, and the water in the cement tank should be discharged, so as to ensure the quality of concrete transportation.

五、在高速公路上行驶时，应将卸料槽降至很低位置，随车身一起转移至垂直位置，并用锁紧装置将卸料槽锁紧在车架上，以防因不安全而晃动，造成伤害和事故，影响其他车辆的运行。如果梯子状况不好，会损坏油轮的油舱轴。

5、 When driving on the expressway, the unloading chute should be lowered to a very low position, and transferred to a vertical position with the body, and locked on the frame with a locking device, so as to prevent the shaking due to insecurity, causing injuries and accidents, and affecting the operation of other vehicles. If the ladder is not in good condition, the oil tank shaft of the tanker will be damaged.

六、卸料前，如果发现水分蒸发，坍落度偏低不能饱满。当用户需要时，可在搅拌筒中适当加水，然后根据进料偏差，以6~10转/分钟的速度旋转30圈后，即可出料。

6、 Before unloading, if water evaporates, the slump is too low to be full. When the user needs, water can be added into the mixing drum properly, and then the material can be discharged after 30 turns at the speed of 6 ~ 10 RPM according to the feeding deviation.

七、混凝土搅拌车在运输混凝土过程中不得将搅拌筒含动，以免出现混凝土离析现象。

7、 The concrete mixer truck shall not move the mixing drum in the process of transporting concrete to avoid concrete segregation.
