4.2. Effects of Terrain on Productivity

Try these first

1. 1.

   What does cycle time refer to in bulldozer operations?

   Hint

   Consider the different phases of operation.

2. 2.

   Define job efficiency briefly.

   Hint

   Think about operating time versus overall time.

3. 3.

   What does a longer haul distance typically do to a bulldozer's push time?

   • Increases it
   • Decreases it
   • Has no effect

   Hint

   Think about how distance affects travel time.

4. 4.

   True or False: Job efficiency indicates how much a bulldozer operates continuously without downtime.

   • True
   • False

   Hint

   Consider how often a machine might be active in practice.

5. 5.

   If a bulldozer has a push distance of 100 meters with a speed of 6 km/h, calculate how long it takes to complete this operation. Consider job efficiency of 40 minutes.

   Hint

   Convert and calculate.

6. 6.

   Discuss the effects of soil type on bulldozer productivity. Provide examples of soil characteristics that enhance or diminish performance.

   Hint

   Reference our discussion on soil types.
