What should I pay attention to when driving a concrete mixer truck?
To drive a concrete mixer truck, for experienced drivers, general knowledge of safe driving 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!
What are the effects of more concrete on the mixer truck?
The mixer trucks below 9 square meters are loaded with more concrete, and the truck will leak during the climbing process; if the 12-square truck mixers are loaded with more concrete, the mixing will be layered, the concrete sand rate will be low, and the particle size of the stones will be too large. Pumping a lot of pebbles.
New mixer trucks are generally prone to problems after a few years of operation?
It usually takes 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.
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 fact, this situation is often cut through the tank with electric welding or gas cutting, and then the solidified concrete is mechanically broken.
What is meant by the top of the mixer truck?
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, the operating linkage mechanism, etc.
Are the hydraulic systems of general mixer truck manufacturers domestic or imported?
Generally, the manufacturer will choose the installation according to the size of the mixer and the needs of the customer. The standard configuration of 6 square meters or less is the domestic system (optional import), and the standard configuration of 6 square or more is the imported system.
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.
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 the circumferential and longitudinal seams use fully automatic seamless welding.
What is the payment method for the mixer truck?
There are many payment methods for mixer trucks. 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 installment payments, and the interest is equal to the bank interest.
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, it depends on whether the slump is too small or the strength of the concrete is too high, or the reason is that the concrete is too sticky. For the above reasons, the concrete can be adjusted appropriately according to the construction requirements; if it is always bad For the next step, it is necessary to consider whether there is a problem with the blade angle and the unloading port.
