Precautions for Start - up of Concrete Mixer

A description of the start mode

Start the concrete mixer using star delta conversion start mode, that is, star start, triangular run. As the mixer main motor power, start at the beginning, the stator coil for the star connection, this can reduce the starting current. To be started after a period of time, the motor speed is approaching the normal speed, then the starter stator coil will be changed to triangular connection, start indicator light, the motor to normal operation.

Second, the note

1. Do not start with load

Start with the load refers to the concrete mixer within the case of material to start. Because the start-up current with a load is very large in a period of time, easy to burn the air switch, contactor, reducing motor life, the mixer material in the case of the correct approach is:

① start the air compressor, the host door open, so that part of the material leak down;

② If the material is not a lot of concrete mixer, you can jog the host, so that the material released until the machine is finished or little complete re-start the material;

③ If the concrete mixer a lot of material, you need to manually clean up part of the above methods described above.

2. Emergency stop is prohibited

Stirring the mixer in the case of material is prohibited to stop the host, because the host to prohibit start with a load. Unless in a particularly urgent situation can stop the heavy truck is working in the mixer.

3. Use the "Emergency Stop" button with caution

The EMERGENCY STOP button is a red mushroom-shaped button located at the top left of the operator panel. When an emergency, no time to deal with the dangerous situation, you can manually shoot the emergency stop button, this button will stop except for bells and all the motor and the implementation of devices, including the mixer. When the danger is removed, the "Emergency Stop" button can be rotated to release it.
