5. Working on the Problem for Balancing Machines

Try these first

1. 1.

   Define gravimetric capacity.

   Hint

   Think about what the manufacturer specifies.

2. 2.

   What is loading time?

   Hint

   Consider this when using machinery.

3. 3.

   What does gravimetric capacity indicate?

   • Maximum load a machine can carry safely
   • Total weight of all materials processed
   • Average cycle time

   Hint

   Relate this to how machines are rated.

4. 4.

   True or False: Overloading a machine can lead to a reduction in operational costs.

   • True
   • False

   Hint

   It often results in repairs and inefficiencies.

5. 5.

   A hydraulic excavator can load a truck in 2 minutes, while the truck takes 30 minutes to complete its cycle. If you have 2 trucks, what would be the ideal number of excavators?

   Hint

   Consider the ratio of times.

6. 6.

   You have a loader with a cycle time of 3 minutes and a load of 9 tons. If the gravimetric capacity of the truck is 18 tons, how many loads can it make in a 60-minute hour?

   Hint

   Use division for time and multiplication for total weights.
