2. Backhoes

Try these first

1. 1.

   What is the ideal angle of swing when using a backhoe?

   Hint

   Think about the position that minimizes cycle time.

2. 2.

   Define height of cut in the context of backhoes.

   Hint

   Consider how it relates to the bucket's function.

3. 3.

   What is the ideal angle between the truck and the backhoe for optimal productivity?

   • 90 degrees
   • 45 degrees
   • 180 degrees

   Hint

   Consider which angle allows for the most direct movement.

4. 4.

   True or False: Lowering the height of cut always increases productivity.

   • True
   • False

   Hint

   Reflect on the relationship between height and ideal conditions.

5. 5.

   A backhoe has a bucket capacity of 4.0 m³ and operates with a fill factor of 0.9. If the angle of swing is 100 degrees, what correction factor would you apply if the optimum height of cut is 5m and the actual cut height is 3m?

   Hint

   Review the concept of correction factors related to height and swing.

6. 6.

   You have a scenario where two trucks are used with a backhoe. One truck has an exchange time of 15 minutes, and another has 10 minutes. How does this variance affect total productive time?

   Hint

   Think about the impact of waiting and efficiency in management.
