1. It is necessary to ensure the cleanliness of the concrete mixer body and remove the dirt and obstacles in the body.
2. Check the oil, circuit and control equipment at all lubrication points before working every day, and add lubricant as required.
3. Medium concrete mixer must implement secondary leakage protection. After the power supply is connected before work, it must be carefully checked. Only after the empty car test is considered qualified can it be used.
4. Before working every day, 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 good, whether there are obstacles around and the lubrication of various parts, etc.
5. Before working every day, add water to mixing drum to idle for 1 to 2 seconds, and check the reliability of clutch and brake.
6. During the operation of concrete mixer, the noise of motor, reducer and transmission gear should be monitored at any time, and whether the temperature rise is too high.
7. Every time the mixer is turned on, it is necessary to check whether the operation of each component is normal. When stopping, also remember to check whether the mixer blade is bent, whether the screw is loose or loose.
8. After each work, the concrete mixer must be cleaned carefully.
Generally speaking, the medium concrete mixer needs to be maintained after working for a period of time. In addition to the daily maintenance, it also needs further maintenance, check and adjust the brake clearance. For example, in the clutch, the wear of the external brake band needs to be replaced, the clearance between mixing blade and scraper and liner should be adjusted, the closure and flexibility of hopper and unloading door should be adjusted, the wear degree of clutch and the algorithm of water distribution system should be normal. The elongation of chain pitch should also be checked for medium concrete mixer driven by chain.
