1. The fixed concrete mixer should be installed on a firm pedestal. If it is used for a long time, the anchor bolt should be buried. If it is used for a short period of time, the wooden pillow should be laid under the machine and leveled and stabilized.
2. The mobile concrete mixer should be installed on a flat and hard floor. It should be fixed with wooden or support frame and kept horizontal. It is not allowed to replace the support with tires. It takes a long time (usually more than 3 months). The tires should be removed and kept in a safe place, and the ends of the axles should be cleaned and rust-proofed.
3. The transmission mechanism, working device, clutch and brake should be tightened, flexible and reliable, and the protective cover is complete.
4. The wire rope of the concrete mixer shall not be scrapped, such as rust, broken wire or flattened.
5. The safety hook on the body should be in good condition. When the hopper is raised, the safety hook should be hung.
6. For the planetary concrete mixer to be excavated with the hopper pit, the bottom of the pit should be tamped, and the bottom end of the loading rail frame should also be tamped or the back of the paving frame should be supported by wood to prevent long working time.
7.The concrete pan mixer should be equipped with a rainproof shed. There is no muddy water around the machine, it is clean and tidy, and all kinds of cards are complete.
8. The homogeneous concrete mixer should be equipped with “one machine, one brake, one leak and one box”. The leakage protector parameter is 30MA×0.1S, the motor insulation resistance value should be greater than 0.5M; the protection zero line should be no less than two, and the console instrument and indication signal are accurate and reliable.
