5 cards from this section. Quick, good the night before a test.
What is the angle of swing in an excavator?
Think about the positions of the bucket during operation.
Define cycle time in the context of excavators.
Consider loading and unloading together.
What is the ideal angle of swing for maximum productivity?
Consider the ideal positioning of the truck.
True or False: A greater angle of swing results in shorter cycle times.
Think about the distance required to swing the bucket.
Calculate the expected productivity of an excavator with an actual height of cut at 3.18 meters, given the optimum is 5.3 meters, and the ideal cycle time is 24 seconds.
Remember to apply both the height correction factor and the effective cycle time.
Devise a plan to minimize haul unit exchange time in a construction project with two trucks and one excavator. Discuss timing and placement strategies.
Factor in operation times and balance number cycles based on busy periods.
