1.3. Effect of Transmission Type on Cycle Time

Try these first

1. 1.

   Define cycle time in bulldozer operations.

   Hint

   Consider what happens in each operational phase.

2. 2.

   What is push time?

   Hint

   Think about the movement of the bulldozer.

3. 3.

   What is the fixed time in the cycle time of a bulldozer?

   • Push Time
   • Maneuver Time
   • Backtrack Time

   Hint

   Consider what part of the cycle time doesn't change.

4. 4.

   True or False: Push time is variable and depends on haul distance.

   • True
   • False

   Hint

   Think about how distance relates to time.

5. 5.

   If a bulldozer has a haul distance of 100 meters and operates at a speed of 4 m/s with a manual transmission maneuver time of 0.1 minutes, calculate the total cycle time.

   Hint

   Calculate push and backtrack times based on speed and distances.

6. 6.

   Discuss the impact of transmission types on productivity when operating in a terrain with steep grades. Provide calculations showing differences between manual and automatic systems.

   Hint

   Consider how grade impacts speed and hence cycle times differently for each transmission type.
