What precautions should be taken when cleaning a concrete mixer

With the development in recent years, the construction of new rural areas, old urban renovation and other aspects is booming. The construction of roads, Bridges, houses and so on is flourishing. As the most important material in engineering construction, concrete mixers are ideal mixing equipment for various construction sites. Compared with bridge erection machines and cranes, the maintenance and upkeep of concrete mixers are relatively easy, but they should not be underestimated. Perhaps a small detail can directly affect the use of concrete mixers, such as the cleaning of concrete mixers.

When cleaning a concrete mixer, the following points should be noted:

First, regularly carry out maintenance and upkeep operations as stipulated in the maintenance regulations, such as cleaning, lubrication, and oiling

Second, before starting the concrete mixer, it is necessary to check whether all the controllers are in good condition. After stopping, pour water and stones into the mixing drum for 10 to 15 minutes for cleaning, and then remove the water and stones. When the operator needs to enter the mixing drum for cleaning, in addition to cutting off the power supply and removing the fuse, the switch box must also be locked.

Thirdly, it is strictly prohibited to remove the concrete accumulated in the concrete mixer drum by hammering with a sledgehammer. Only chisels can be used for removal.

Fourth, in severe cold seasons, after work is completed, the mixer drum should be washed with water and the water in the water pump, water tank and water pipes should be drained completely to prevent the water pump, water tank and water pipes from freezing and being damaged.
