3 cards from this section. Quick, good the night before a test.
Define what a scraper is.
Think about what scrapers do in construction.
What is cycle time?
Consider the timing from start to finish in scrapping.
What happens when the number of scrapers is less than the balanced number?
Think about who is in charge with fewer resources.
True or False: Using more scrapers always results in lower production costs.
Consider both sides of costs and productivity.
A project requires 1000 cubic meters to be moved. If each scraper has a capacity of 19.82 bank cubic meters and takes an average cycle time of 7.78 minutes, how many scrapers would you need to efficiently complete the job in 2 hours?
Consider the total volume, productivity rates, and how many scrapers would be needed to meet the time limit.
Evaluate how the density of soil (hard vs. loose) affects the production rates. Discuss a strategy to improve production rates if faced with harder soil conditions.
Think about the relationship between soil condition and equipment performance.
