10 Tips that you should know about the concrete mixer truck

Concrete is a material that is composed of water, sand, and cement. We usually use it in the process of building houses and road repairs. However, in many construction sites, these materials cannot be mixed on the spot to make concrete. What to do? We need a vehicle called concrete mixer truck to transport the ready mixed concrete to the site.

To better use the special vehicle, here we list some tips that you need to know about the concrete mixer truck.

10 Tips that you should know about the concrete mixer truck


1. What should a concrete mixer truck operator pay attention to?

Besides the common sense for safety, the driver needs also to note that the concrete is fluid. When the vehicle turns sharply, the driver must reduce the speed to avoid the centrifugal force generated by the concrete turning to make the vehicle unstable!

2. How many types of concrete mixer trucks are there?

According to the water ratio, there are 3 types of concrete mixer trucks: wet type, dry type, and semi-dry type.

3. Why does the concrete drum keep rotating always?

The concrete mixer truck is a special vehicle used to transport concrete. Because the truck always carries a rotating mixing tank, we also call it a snail truck. Buy why the mixing tank keeps rotating? That is because concrete is composed of stone, sand, cement, and water. If it doesn’t turn during the transportation, the material will separate up: the stone will sink to the bottom, sand in the middle, and water on the top. And the concrete will harden in the drum.

4. How to prevent the concrete from hardening in the drum?

The tank is often cut open by electric welding or gas cutting, and then the solidified concrete is mechanically broken.

5. It is difficult to discharge the concrete, what to do?

Check the material ratio. If the concrete strength is too high or concrete is too sticky, it will be difficult to discharge. You can adjust the raw material ratio according to the requirement of the project. If the problem persists, you should consider the problem of the discharge system.

6. Which welding tech is used for the concrete mixer truck?

Nowadays, most manufacturers use fully automatic seamless welding for the welding of the entire concrete mixer truck, and both the circular seam and the longitudinal seam use fully automatic seamless welding.

7. Is it better to choose a volume pump or the variable pump as the hydraulic pump of the small square volume mixer?

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 we recommend that the customer choose the variable pump.

8. After how many years of operation, the truck is generally prone to problems?

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.

9. What are the effects if I charge more concrete on the mixer truck?

If we load more concrete in the mixer trucks below 9 square meters, and the truck will leak during the climbing process; As for the 12-square truck mixers, the mixing will layer, the concrete sand rate is low, and the particle size of the stones is too large. There will be a lot of pebbles for pumping a lot of pebbles.

10. How to maintain the concrete mixer trucks?

Concrete mixer trucks are professionally used to transport concrete. In order to prolong its service life and create more benefits, we need to pay attention to maintenance at all times.

  • Check and find problems and troubleshoot
  • Ensure that there is enough water in the water tank, with water reducing agent.
  • When the engine starts, confirm that the mixing tank is in a stopped state.
  • The mixing drum should be reversed before loading.
  • Clean up the charging feed after loading.
  • Let the mixing tank run at full speed for one or two minutes before discharging.
  • The mixing tank must be rinsed carefully.
