Florida DOT Concrete Batchman/Operator Practice Exam

What should not be done when hauling concrete in mixers regarding the load?

1. Haul with only half the rated capacity

2. Haul with more than the rated capacity

3. Haul with less than the minimum capacity

4. Haul with a full capacity but no aggregates

The correct answer is: Haul with more than the rated capacity

When hauling concrete, it is essential to adhere to the mixer’s rated capacity to ensure safety, quality, and compliance with industry standards. Hauling with more than the rated capacity can lead to several significant issues. Exceeding the rated capacity might cause the mixer to operate inefficiently, potentially leading to mechanical failure or accidents during transport. Mixing too much concrete can also influence the quality of the concrete itself; it may not mix correctly, resulting in a compromised product that does not meet the required specifications for strength and durability. Understanding the importance of maintaining the appropriate load capacity helps ensure that the concrete arrives at the job site in good condition and minimizes the risks associated with overloading the mixing equipment. This practice also promotes safety for individuals involved in the hauling process and helps maintain the longevity and reliability of the concrete mixing equipment.
