Summary of common problems of concrete mixer truck

Concrete mixer trucks are tank-type special trucks used to transport concrete. Everyone must have a certain understanding. Because the concrete ratio of concrete mixer trucks is scientific and the mixing is even, most construction sites are now using them. And how much do you know about the professional knowledge of mixer trucks?

1. What should I pay attention to when driving a concrete mixer truck?

To drive a concrete mixer truck, for an experienced driver, general safe driving knowledge is good. What I want to remind here is that because the concrete is fluid, when the vehicle turns sharply, the speed must be reduced to prevent the centrifugal force generated by the concrete from making the vehicle unstable!

2. What are the effects of more concrete on the mixer truck?

If there is too much concrete in the mixer under 9 square meters, the truck will leak during the climbing process; if the 12 square mixer is equipped with too much concrete, the mixing will be layered, the concrete sand rate is low, and the gravel particle size is too large. Pumping a lot of stones.

3. New mixer trucks are generally prone to problems after a few years of operation?

It is generally five years to pull dry materials and seven years for wet materials. Generally, mixer trucks are prone to problems after 3 years. The problems of mixer trucks have a lot to do with personal maintenance and manufacturers.

4. What should I do if the concrete solidifies in the mixer truck?

After the concrete is solidified, its main components are dicalcium silicate and tricalcium silicate. In theory, hydrochloric acid can react with it to release its solid state. But in fact it is difficult to operate, because the feed port of the mixer truck is very small, the amount of hydrochloric acid is difficult to control, and the hydrochloric acid can also react with the tank body of the mixer truck. In this situation, the tank is often cut open by electric welding or gas cutting, and then the solidified concrete is mechanically broken.

5. What does the top of the mixer truck mean?

The top of the mixer truck refers to things other than the chassis fender, including the mixing tank and support, the inlet and outlet hopper, the hydraulic system and the reducer, the water tank and the pipeline, and the operating linkage mechanism.

Generally, manufacturers will choose the equipment according to the size of the mixer and the needs of customers. The standard configuration of 6 square meters or less is a domestic system (optional import), and the standard configuration of 6 square meters or more is an imported system.

7. Is the hydraulic pump of the small square volume mixer better the selected volume pump or the variable pump?

The hydraulic pump is the main component of the mixer truck. Generally, the mixer truck with less than 6 square meters is the standard fixed pump, but it is recommended that the customer choose the variable pump.

8. What is the welding process of the mixer truck?

Nowadays, most manufacturers use fully automatic seamless welding for the welding of the entire car, and both circular and longitudinal seams use fully automatic seamless welding.

9. What is the payment method of the mixer truck?

There are many ways to pay for the mixer truck. You can buy the car in full or in installments. Generally, manufacturers will have certain discounts for the full amount of the car. There is no discount on installments, and the interest is equal to the bank interest.

10. What should I do if the concrete mixer truck is exhausted? Is there a better way other than adding water?

If it is because of the concrete, then it depends on whether the slump is too small or the concrete strength is too high, or the concrete is too sticky and not good. The above reasons can be adjusted according to the construction requirements; if it is always bad Under the circumstances, it is necessary to consider whether there is a problem with the blade angle and the cutting port.
