Mixer truck can mix plastic, hard, flowing concrete and lightweight aggregate and mortar, so daily maintenance is essential.
1. It is necessary to ensure the cleanness of the mixer body and remove the dirt and obstacles in the body.
2. Check the oil, circuit and control equipment at each lubricating place before daily work, and add lubricating oil as required.
3. The mixer must implement secondary leakage protection. After the power is connected before going to work, it must be checked carefully. It can only be used after passing the test run of empty car.
4. Before daily work, it is necessary to check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is in good condition, whether there are obstacles around and the lubrication of various parts.
5. Before daily operation, add water to the mixing drum and run idle for 1 to 2 seconds. Meanwhile, check the reliability of clutch and brake device.
6. During the operation of concrete mixer, it is necessary to check whether the noise of motor, reducer and transmission gear is normal and whether the temperature rise is too high,
7. Every time after the mixer is started, it is necessary to check whether the operation of each part is normal. When shutdown, also remember to check whether the mixer blade is bent, whether the screw is knocked down or loose.
8. After each work, the concrete mixer must be cleaned carefully.
In general, the mixer needs to be maintained after working for a period of time. In addition to the daily maintenance work, it also needs further maintenance, checking and adjusting the brake clearance. For example, the inner and outer brake belts of the clutch are worn out and need to be replaced, the clearance between the mixing blade and the scraper and the lining plate is adjusted, the sealing and flexibility of the upper hopper and the discharge door, the wear degree of the clutch and the algorithm of the water distribution system are normal. The extension of the chain pitch should be checked for the mixer truck with chain drive.
