1. Do well in lubrication
Before the concrete mixer works every day, check the oil, circuit and control equipment at each lubrication point, and fill the lubricating oil as required. However, there are many places where the mixer needs to be lubricated. The method and quantity of adding lubricant are different. Sometimes, a new lubricant needs to be replaced.
2 do a good job in cleaning
The concrete mixer must ensure the cleanness of the concrete mixer body and remove the dirt and obstacles in the body, especially the foreign matters between the mixing blade or side blade of the concrete mixer and the inner wall of the tank.
3. Do a good job in inspection
① Before daily operation, it is necessary to check whether the transmission clutch and brake are flexible and reliable, whether the steel wire rope is damaged, whether the track pulley is in good condition, whether there are obstacles around and the lubrication of various parts, etc;
② The mixer must be provided with two-level leakage protection. After the power supply is connected before going to work, it must be checked carefully. It can be used only after it is considered qualified after the idle test run;
③ Before the concrete mixer works every day, add water into the mixing drum and idle for 1 to 2 seconds. At the same time, check the reliability of the clutch and brake device.
When the concrete quantity is large and the construction period is long, medium or large fixed concrete mixer or mixing station should be selected. If the concrete quantity is small and the construction period is short, the medium and small mobile mixer should be selected.
When the mixing concrete is plastic or semi plastic, the self dropping mixer should be selected. It has simple structure and convenient maintenance. Compared with the forced type, the mixing effect is slightly worse. If the mixing concrete is high strength, dry hard or light concrete, the forced mixer should be selected. It has complex structure and high maintenance requirements, but it has good mixing effect and high efficiency.
