2. Dumping Time

Try these first

1. 1.

   What are the three main types of hauling units?

   Hint

   Think of the shapes of the trucks and how they unload.

2. 2.

   Define gravimetric capacity.

   Hint

   It relates to how overloaded machinery can face damage.

3. 3.

   What is one factor that affects dumping time?

   • Machine type
   • Time of day
   • Weather

   Hint

   Recall our discussion on different trucks.

4. 4.

   True or False: Overloading a truck can lead to higher operational costs.

   • True
   • False

   Hint

   Think about how heavy loads affect your tires.

5. 5.

   A site requires trucks to dump wet sand, which is known to be denser. If the gravimetric capacity of a truck is 15 tons, and each load weights 10 tons, how would you calculate the efficient dumping time considering the congestion from multiple trucks waiting to unload?

   Hint

   Think of how one truck's delay can snowball as others line up to dump.

6. 6.

   Given two types of dump trucks where the bottom dump truck leads the unloading process with a time of 3 minutes and the rear dump takes 5 minutes, if you have 10 loads to dump under favorable conditions, calculate the efficiency ratio between the two.

   Hint

   Efficiency is all about how fast you can complete the tasks at hand!
