4 cards from this section. Quick, good the night before a test.
What is the ideal angle of swing for maximum productivity?
Consider how the excavator needs to load the truck.
Define truck spotting clearance.
Think about the movement of the excavator’s tail.
What is the ideal angle of swing for an excavator?
This is the position for optimal productivity.
True or False: The actual height of cut should always equal the optimum height of cut for maximum productivity.
Think about how differences in heights affect productivity.
Given that the cycle time increases significantly as the angle of swing goes above 90 degrees, analyze a scenario where the angle is 120 degrees. Discuss the implications for excavator productivity.
Consider how productivity metrics change with increasing cycles.
Assume an excavator operates at a height of cut that is 40% of the optimum height. Discuss how this would impact productivity and what actions could be taken to rectify the situation.
Reflect on the relationship between height and productivity.
