2.2. Loading Methods

Try these first

1. 1.

   Define cycle time in the context of scraper operations.

   Hint

   Think about all the activities that a scraper performs.

2. 2.

   What are the two categories of cycle time?

   Hint

   Consider what might remain constant versus what changes with distance.

3. 3.

   What are the two main components of cycle time?

   • Fixed and Variable
   • Load and Dump
   • Active and Passive

   Hint

   Recall the definitions we discussed earlier.

4. 4.

   True or False: Overloading a scraper can improve productivity.

   • True
   • False

   Hint

   Consider the loading growth curve we reviewed.

5. 5.

   Consider a construction site where the haul distance increases. Discuss how this will impact the variable time and overall cycle time of scrapers.

   Hint

   Consider how travel affects time taken for each component.

6. 6.

   A scraper is consistently overloaded, resulting in slower loading times. Calculate the potential decrease in productivity if loading times increase by 50% due to resistance.

   Hint

   Reflect on the impact of diminished returns on overall output.
