5 cards from this section. Quick, good the night before a test.
What is cycle time?
Think about all the steps involved in using a scraper.
What does ADBT stand for?
Focus on the speed-related components.
What are the components of cycle time?
Think about each step involved in using the scraper.
True or False: Loading a scraper to maximum capacity will always increase its productivity.
Consider how material dynamics work in a confined space.
Calculate the cycle time if a scraper has the following times: LT = 0.8 min, HT = 3.5 min, DT = 1.2 min, RT = 2.3 min, ST = 0.5 min, TT = 0.25 min. Consider also ADBT = 0.15 min. What is the total cycle time?
Add all the specified times together following the formula.
A project has two haul routes, one taking 5 min to traverse and the other taking 3 min. The loader takes 2 min, dump time is 1 min, and return time is 4 min. What can be done to reduce the cycle time?
Identify the longest process and see how you can enhance its efficiency.
