Self - loading concrete mixer trucks are essential equipment in the construction industry. Proper operation can not only ensure the quality of concrete but also extend the service life of the equipment. In this article, we will share some important operating experience and skills.
Before using a self - loading concrete mixer truck, the first step is to fix the vehicle firmly on the ground. This is crucial for safety and stability during the mixing process. According to industry statistics, about 80% of minor accidents during the operation of mixer trucks are related to unstable vehicle placement. By ensuring the vehicle is well - fixed, you can significantly reduce the risk of such accidents.
When adding raw materials, it is necessary to add aggregates, water, cement, and other ingredients in sequence. Aggregates usually account for about 60% - 75% of the total volume of concrete, water about 15% - 20%, and cement about 10% - 15%. The order of addition is very important. Adding them in the correct order can ensure a more uniform mixture. For example, adding cement after aggregates and water can prevent the cement from forming lumps, which is beneficial to the quality of the final concrete product.
The mixing time is a key factor affecting the quality of concrete. Generally, the mixing time should be between 3 - 5 minutes for small - scale mixer trucks and 5 - 7 minutes for large - scale ones. Sufficient mixing time can ensure that all raw materials are fully combined, improving the strength and durability of the concrete. Inadequate mixing time may lead to uneven distribution of components, resulting in a decrease in concrete quality.
When using a flat - mouth mixer truck to mix concrete, the loading action should not be too fast or too violent. Fast and rough loading may cause the raw materials to splash out, resulting in waste and potential safety hazards. Before reversing, it is necessary to carefully observe the terrain. According to safety reports, about 15% of mixer truck accidents are related to reversing operations. Therefore, a thorough observation of the surrounding environment can effectively avoid collisions and other accidents.
During the empty - load operation and the transportation of concrete, the mixing drum should not stop rotating. This can prevent the concrete from solidifying inside the drum, ensuring smooth transportation and subsequent use.
