2.5. Versatile Attachments and Applications

Try these first

1. 1.

   What is the ideal angle of swing for maximum productivity?

   Hint

   Think about angles that facilitate easy loading and dumping.

2. 2.

   How is the actual height of cut calculated?

   Hint

   Compare the heights involved in excavation.

3. 3.

   What is the ideal angle of swing for maximum productivity?

   • 70 degrees
   • 80 degrees
   • 90 degrees

   Hint

   Think about the angle that allows most efficient operations.

4. 4.

   True or False: A greater angle of swing leads to shorter cycle times.

   • True
   • False

   Hint

   Consider what happens to the swing path.

5. 5.

   A shovel with a heaped volume of 5m³ operates with a fill factor of 0.9. If the cycle time is 25 seconds, calculate the productivity if the optimal height is 6m but the actual height is 4.5m.

   Hint

   Remember to adjust for the actual height.

6. 6.

   How would you manage a situation where the haul unit exchange time is longer than expected due to unavailability of trucks on site?

   Hint

   Focus on balancing operations to prevent downtime.
