2. Estimating Productivity of the Bulldozer

Try these first

1. 1.

   Define cycle time in the context of bulldozer operations.

   Hint

   Look for the components that make up the cycle time.

2. 2.

   What is push time?

   Hint

   Consider the factors that might affect this duration.

3. 3.

   What is the main component of cycle time?

   • Push time
   • Backtrack time
   • Maneuver time
   • All of the above

   Hint

   Think about the elements that make up the cycle.

4. 4.

   True or False: Job efficiency must always be considered when calculating productivity.

   • True
   • False

   Hint

   Consider why machines don't run the entire hour.

5. 5.

   A bulldozer is assigned a project requiring it to move material over varying slopes. If the push time varies across conditions, how would you utilize this information to optimize operational output?

   Hint

   Consider what types of adjustments in operation could reduce push time.

6. 6.

   When using production curves, you notice a discrepancy between estimated and actual performance. What factors could account for this variance, and how could you adjust your estimates accordingly?

   Hint

   Think about the external conditions that might alter expected productivity.
