5.1. Finding Balance Number of Bucket Loads

Try these first

1. 1.

   What is gravimetric capacity?

   Hint

   Think of how much weight a truck can handle.

2. 2.

   What does cycle time refer to?

   Hint

   Consider the time spent loading, dumping, and returning.

3. 3.

   What ratio is recommended for balancing the truck and bucket capacities?

   • 1:2
   • 2:3
   • 4:5
   • 1:1

   Hint

   Think about how trucks should effectively match the excavator's size.

4. 4.

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

   • True
   • False

   Hint

   Consider the long-term effects of machinery performance.

5. 5.

   A truck has a gravimetric capacity of 15 tons, and the load is wet clay with a density of 1.8 tons/m3. What is the maximum volume the truck can carry without exceeding its capacity?

   Hint

   Remember to convert weight capacity to volume using density.

6. 6.

   If the excavator's bucket cycle time is 1.5 minutes and the total truck cycle time is 35 minutes, how many trucks would theoretically balance with one excavator?

   Hint

   Calculate the division carefully and consider rounding rules.
