4 cards from this section. Quick, good the night before a test.
What is cycle time composed of?
Think about the different tasks a bulldozer does.
What is fixed time in bulldozer operations?
Consider tasks that don't change with distance.
What does cycle time consist of?
Think about what a bulldozer does from start to finish.
True or False: Fixed time changes depending on haul distance.
Consider which components remain constant.
Calculate the productivity of a bulldozer that completes a cycle in 30 minutes with a blade load of 100 cubic meters. If job efficiency is 75%, what is the effective productivity?
Remember to convert minutes to hours when calculating.
Given that the bulldozer operates under poor visibility and an experienced operator takes longer, adjust the productivity estimate by applying a correction factor of 0.85. If initial productivity was 180 cubic meters per hour, what is the adjusted productivity?
Use the formula for adjusting productivity based on the factors discussed.
