1.3. Truck Spotting Clearance

Try these first

1. 1.

   What is the ideal angle of swing for maximum productivity?

   Hint

   Consider how the excavator needs to load the truck.

2. 2.

   Define truck spotting clearance.

   Hint

   Think about the movement of the excavator’s tail.

3. 3.

   What is the ideal angle of swing for an excavator?

   • 60 degrees
   • 90 degrees
   • 120 degrees

   Hint

   This is the position for optimal productivity.

4. 4.

   True or False: The actual height of cut should always equal the optimum height of cut for maximum productivity.

   • True
   • False

   Hint

   Think about how differences in heights affect productivity.

5. 5.

   Given that the cycle time increases significantly as the angle of swing goes above 90 degrees, analyze a scenario where the angle is 120 degrees. Discuss the implications for excavator productivity.

   Hint

   Consider how productivity metrics change with increasing cycles.

6. 6.

   Assume an excavator operates at a height of cut that is 40% of the optimum height. Discuss how this would impact productivity and what actions could be taken to rectify the situation.

   Hint

   Reflect on the relationship between height and productivity.
