1. What should I pay attention to when driving a concrete mixer?
For experienced drivers, the general knowledge of safe driving is good. It should be reminded that since the concrete is fluid, when the vehicle turns sharply, the speed must be reduced to avoid the centrifugal force generated by the concrete turning making the vehicle unstable!
2. What are the effects of more concrete in the mixer?
If the mixer truck below Jiufang is loaded with more concrete, the truck will leak during climbing. If the mixer truck below 12fang is loaded with more concrete, the mixing will be layered, the concrete sand rate is low, the stone particle size is too large, and there are many stones pumped to the construction site.
3. The new mixer is easy to have problems after driving for several years?
Generally, it takes five years to pull dry materials and seven years to pull wet materials. Generally, the mixer truck is prone to problems after three years. The problems of the mixer truck are closely related to personal maintenance and manufacturers.
4. What if the concrete solidifies in the mixer?
After the concrete is solidified, its main components are dicalcium silicate and tricalcium silicate. Theoretically, hydrochloric acid can react with it to remove its solid shape. But in fact, it is difficult to operate because the material port of the mixer is very small, the amount of hydrochloric acid is difficult to control, and hydrochloric acid can also react with the tank of the mixer. In practice, the tank body is often cut by electric welding or gas cutting, and then the solidified concrete is mechanically broken.
5. What does loading on the mixer refer to?
Loading on the mixer truck refers to the things of the mixer truck other than the chassis fender, including the mixing tank and support, inlet and outlet hopper, hydraulic system and reducer, water tank and pipeline, operating linkage, etc.
