3 cards from this section. Quick, good the night before a test.
Define Haul Unit Exchange Time.
Think about the time it takes between truck movements.
What is the ideal angle of swing for an excavator?
Visualize the placement of trucks and excavators.
What is Haul Unit Exchange Time?
Focus on the processes between truck movements.
True or False: An angle of swing greater than 90 degrees will improve productivity.
Remember the ideal positions discussed.
An excavator positioned with a swing angle of 120 degrees and an actual height of cut at 3m when the optimum height is 4m is observed. Determine the correction factor and the effect on productivity.
Consult the reference table for correction factors.
Design a detailed workflow for a construction project that maximizes haul unit exchange time. Consider time estimates and potential delays.
Use a diagram to outline the workflow.
