2 cards from this section. Quick, good the night before a test.
What is the angle of swing?
Think about the horizontal swing of the excavator's bucket.
Define cycle time.
Consider how long it takes for the excavator to complete its task.
What effect does a swing angle greater than 90 degrees have on cycle time?
Consider how distance affects travel time.
True or False: The ideally positioned truck adds no correction factor to productivity calculations.
What is the ideal condition to remember?
If the ideal swing angle is maintained at 70 degrees while the height of cut is 3 meters and optimal height is 5 meters, determine the correction factor based on hypothetical values from a provided chart.
Check the values provided in the textbook or table for specifics.
A shovel operates with a heaped bucket volume of 4 cubic meters and takes 30 seconds per cycle. If it works efficiently for 50 minutes, calculate its potential output using the given formula and considering an efficiency percentage.
Remember to adjust the figure for the time worked effectively.
