1.2. Maneuver Time

Try these first

1. 1.

   Define maneuver time in the context of bulldozer operations.

   Hint

   Think about what the operator does during operation.

2. 2.

   What are the components of cycle time?

   Hint

   Recap the definitions discussed in class.

3. 3.

   What time is included in maneuver time?

   • Push time
   • Time taken to change gear
   • Backtrack time

   Hint

   Consider what adjustments are made during operations.

4. 4.

   True or False: Backtrack time is usually equal to push time.

   • True
   • False

   Hint

   Think about the state of the material being moved.

5. 5.

   If a bulldozer has a blade load of 200 kg and operates with a cycle time of 20 minutes, what is the productivity in loose meters cubed per hour if it maintains 75% job efficiency?

   Hint

   Remember to convert your time into hours and factor in job efficiency.

6. 6.

   Calculate the time required for a bulldozer to push material 120 meters at a speed of 10 meters per minute, including 2 minutes for maneuver time.

   Hint

   Calculate push time first and then sum it with maneuver time.
