Is it enough just to have a heavy vehicle license to be a mixer driver?
The answer, of course, must be no! Although the mixer is generally defined as a truck-mounted equipment, it has different features from all other trucks traveling on the highways, roads and also at the construction sites.
The center of gravity of the concrete trucks is high and its location changes at any time due to the constantly moving concrete in the drum. With the effect of centrifugal force created by the rotating drum, the concrete truck seems ready to rollover at any moment!
In addition to these, there are some limitations depending on the load carried by the mixer ie the concrete. Wet concrete must be mixed during the entire transport to preserve its properties. Also it has to be poured into the forms within 60-120 minutes after it is filled in the drum at the plant.
There are some companies that see the concrete truck drivers as concrete experts
when they enter the site and expect them to take all responsibility for the product once it is loaded into the drum. Therefore the basic concrete knowledge in any case is important for concrete truck drivers.
On the other hand mixer drivers have a very important role at the dispatch starting from filling the concrete to the vehicle in the plant and pouring it into forms or pumps hopper at site. And all concrete truck drivers should be aware of this duty at all stage.
The content of this handbook consists of necessary information for the safe operation of concrete trucks. All concrete truck drivers may find some new and important information that they have not encountered so far. That’s why I recommend reading this handbook and even working on some topics together with colleques.
