4 cards from this section. Quick, good the night before a test.
What are the three components of cycle time?
Think about what actions a bulldozer performs in a single operational cycle.
How does job efficiency affect productivity calculations?
What fraction do you apply to productivity when calculating it?
What is defined as the total time taken for a bulldozer to complete one full operational cycle?
Think about what other factors are included within this total time.
True or False: Job efficiency is always 60 minutes in an hour.
Consider how real-world conditions affect working time.
A bulldozer is located on a site with a 20% incline. If its output is calculated at flat terrain at 10 cubic meters per hour, estimate the corrected output considering the incline.
Consider how inclines typically affect bulldozer speed and productivity.
If the cycle time for a bulldozer is 40 minutes, and the job efficiency is revealed to be only 30 minutes in an hour, calculate the productivity assuming a blade load of 2.5 cubic meters.
Remember to adjust the calculated productivity based on job efficiency to reflect actual working time.
