What should I pay attention to when driving a concrete mixer truck?
Driving a concrete mixer truck is a common sense of safe driving for experienced drivers. Here, it is important to remind you that because the concrete is in a fluid state, when the vehicle makes a sharp turn, it is necessary to reduce the speed to avoid the centrifugal force generated by the concrete during the turn making the vehicle unstable!
What are the impacts of loading more concrete on the mixer truck?
Mixers with a capacity of less than 9 cubic meters are overloaded with concrete, which may leak during climbing; If the 12 cubic meter mixer truck is loaded with too much concrete, the mixing will be layered, resulting in a low sand content of the concrete and a relatively large particle size of the stones. Therefore, there are too many stones to be pumped to the construction site.
3. How many years after driving a new mixer truck, it is relatively easy to have problems?
Generally, it takes five years for dry materials to be pulled, and seven years for wet materials to be pulled. Generally, the mixer truck is prone to problems after three years. The problems of the mixer truck are closely related to personal maintenance and the manufacturer.
What should I do if the concrete solidifies in the mixer truck?
After solidification, the main components of concrete are dicalcium silicate and tricalcium silicate. In theory, hydrochloric acid can react with it to remove its solid state shape. However, it is actually difficult to operate because the feed opening of the mixer truck is very small, and the amount of hydrochloric acid is difficult to control, and hydrochloric acid can also react with the tank body of the mixer truck. In practice, this often occurs by cutting the tank body with electric welding or gas cutting, and then mechanically crushing the solidified concrete.
5. What does it mean to install on a mixer truck?
The upper installation of the mixer truck refers to the things other than the chassis fender of the mixer truck, including the mixing tank and support, the inlet and outlet hopper, the hydraulic system and reducer, the water tank and pipeline, and the operating linkage mechanism.
6. Is the hydraulic system of the general mixer truck manufacturer domestically made or imported?
Generally, manufacturers will choose to install the mixer according to the size of the truck and the customer's needs. The standard configuration below 6 square meters is a domestic system (optionally imported), and the standard configuration above 6 square meters is an imported system.
7. Is the hydraulic pump of the small volume mixing truck better selected as a metering pump or a variable displacement pump?
The hydraulic pump is the main component of a mixer truck. Generally, mixers with a capacity of less than 6 square meters are standard quantitative pumps, but it is recommended that customers choose to install variable displacement pumps.
8. What is the welding process for the mixer truck?
Currently, most manufacturers use fully automatic seamless welding for the welding of the entire vehicle, and both circumferential and longitudinal seams use fully automatic seamless welding.
9. What is the payment method for the mixer truck?
There are various payment methods for mixing trucks, including full payment or installment payment. Generally, manufacturers will provide a certain discount for full payment, but there is no discount for installment payment, and the interest is equal to the bank interest.
10. What should I do if the concrete mixer truck is laborious in discharging? Is there a better way besides adding water?
If it is due to concrete, it is necessary to determine whether the slump is too low, the strength of the concrete is too high, or the concrete is too sticky and does not work well. For the above reasons, the concrete can be adjusted appropriately according to the construction requirements; If it is always difficult to unload, it is necessary to consider whether there is a problem with the blade angle and the unloading port.
