The automatic loading mixer will run in when transporting heavy load concrete. Do you know how to carry out the test run? Here are the steps.

1、按所需混凝土配比确定供水量，并调节时间继电器到相应的给水时间。

1. The water supply is determined according to the required concrete proportion, and the time relay is adjusted to the corresponding water supply time.

2、启动搅拌电动机运转。

2. Start the mixing motor.

3、关闭卸料门，在料斗内加入所需的混合料后，提升料斗，料斗应运行平稳并能自如停止在轨道的任意位置，若有打滑现象，应先将料斗放入坑底，然后调整制动电机上的大螺母。料斗提升正常，制动可靠后，向搅拌罐内投料，同时启动水泵向搅拌罐内供水。

3. Close the discharge door and add the required mixture into the hopper. After lifting the hopper, the hopper should run smoothly and stop at any position of the track freely. If there is slippage, the hopper should first be put into the bottom of the pit and then adjust the large nut on the brake motor. After the hopper is lifted normally and the brake is reliable, the material is fed into the mixing tank, and the water pump is started to supply water to the mixing tank.

4、搅拌25—35秒后，启动卸料门卸料。

4. After mixing for 25-35 seconds, start the discharge door to unload.

5、在上述各项试运转过程中，如发现不正常情况，应立即停机检查，排除故障，然后再次试验，直到正常为止。

5. In the process of the above test run, if abnormal conditions are found, stop the machine immediately for inspection, remove the fault, and then test again until it is normal.

自动上料搅拌车的重载试运转就是上面介绍的这个样子，车辆在重载时进行试运转是非常有必要的，司机师傅们一定要注意了。

The heavy load test run of the automatic feeding mixer is described above. It is very necessary to test run the vehicle under heavy load. The drivers must pay attention to it.
