3.2. Calculating Return Time

Try these first

1. 1.

   Define gravimetric capacity.

   Hint

   Think about the manufacturer's specifications.

2. 2.

   What factors affect loading time?

   Hint

   Consider how long it takes to fill a truck.

3. 3.

   What is gravimetric capacity?

   • Maximum load the machine can handle
   • Average load the machine can handle
   • Total weight of the machine

   Hint

   Remember, it’s about safety limits.

4. 4.

   True or False: Loading time is only affected by the type of material being loaded.

   • True
   • False

   Hint

   Consider all influencing factors.

5. 5.

   A truck with a gravimetric capacity of 12 tons is loaded with a material having a density of 3 tons per cubic meter. What is the maximum volume it can carry?

   Hint

   Remember the formula for calculating volume based on weight and density.

6. 6.

   Given a loader that fills a truck in 2 minutes and a truck cycle time of 40 minutes (including unload and return), calculate how many truckloads can be filled in one hour.

   Hint

   Keep in mind total time must align with offerings for balancing machinery!
