1. Cycle Time of the Bulldozer

Try these first

1. 1.

   What are the two main components of cycle time?

   Hint

   Think of the time taken during operations.

2. 2.

   What is push time dependent on?

   Hint

   What influences the distance pushed?

3. 3.

   What time is considered variable in the bulldozer cycle?

   • Maneuver time
   • Push time
   • Both

   Hint

   Think about which aspect changes based on distance.

4. 4.

   True or False: Cycle time includes just the time spent pushing material.

   • True
   • False

   Hint

   Recall the definition of cycle time.

5. 5.

   Consider a bulldozer with a blade load of 2 cubic meters and a cycle time made up of 10 minutes of push, 5 minutes of backtrack, and 2 minutes of maneuvering. Calculate the productivity in cubic meters per hour.

   Hint

   Remember to convert time into hours for your productivity calculation.

6. 6.

   If a bulldozer has a fixed cycle time of 15 minutes but operates under a dense material with a correction factor of 0.8, what is the new effective cycle time?

   Hint

   How do correction factors change your baseline calculations?
