3 cards from this section. Quick, good the night before a test.
What does rimpull refer to?
Think about the wheeled machines and their power.
What is the coefficient of traction?
Consider how well a machine can grip the ground.
The maximum usable rimpull depends on which of the following factors?
Think about what allows a machine to provide effective pulling force.
True or False: The more scrapers used in a project will always improve productivity.
Consider the dynamics between scrapers and pushers in operations.
A project manager considers using different numbers of scrapers ranging from 4 to 7 with pushers always at one. Calculate expected productivity for each case and determine the best choice.
Make sure to factor in efficiency and each specific scraper's cycle time.
A scraper operates at various altitudes. Calculate the adjusted rimpull if it starts at sea level and rises to 1200 meters.
Work through the altitude increments methodically, keeping track of performance drops.
