2.4. Backhoe and Loader Combination

Try these first

1. 1.

   What is the ideal angle for positioning a truck next to an excavator?

   Hint

   Think about the optimal position for minimizing swing.

2. 2.

   Define cycle time in your own words.

   Hint

   It involves both loading and unloading.

3. 3.

   What is the preferred angle for truck positioning to maximize productivity?

   • 60 degrees
   • 90 degrees
   • 120 degrees

   Hint

   Remember the main idea of reducing swing.

4. 4.

   True or False: Increasing the angle of swing decreases cycle time.

   • True
   • False

   Hint

   Think about how swing mechanics operate.

5. 5.

   A project requires using a backhoe with a heaped bucket capacity of 3 m³. If the cycle time is 25 seconds, calculate the productivity per hour. Consider the optimal height is achieved.

   Hint

   Use the formula provided in lessons regarding productivity.

6. 6.

   Discuss how adjusting the angle of swing from 90 degrees to 120 degrees would affect an ongoing excavation project concerning time management and productivity.

   Hint

   Consider the implications of increased cycle times on project efficiency.
