Question 1

What does cycle time consist of?

  • Only fixed time
  • Only variable time
  • Both fixed and variable time

💡 Hint: Remember which timings are varying and which are constant.

Question 2

True or False: Productivity increases when operating down a slope.

  • True
  • False

💡 Hint: Think about how gravity affects speed.

Challenge Problems

Push your limits with challenges.

Question 1

Using an ideal production figure of 50 cubic meters per hour from a production curve, how would the productivity change if the correction factor for material density was identified as 0.85 due to heavier soil?

💡 Hint: Apply the correction factor to the ideal production value.

Question 2

A bulldozer has a blade load capacity of 2.5m³, operates at a speed of 3m/min, and the haul distance is 90 meters. Calculate the productivity per hour and reduce it if the job efficiency is only 40 minutes per hour.

💡 Hint: Break down the total time into push and maneuver components to find effective productivity.
