A construction crew is planning to optimize their earth-moving operation. If they have three scrapers each needing an ADBT of 0.25 minutes and a haul distance costing them 4 minutes each way for a loaded trip, and a return time of 3 minutes, calculate the cycle time if load time is 1.5 minutes and dump time is 1 minute.
💡 Hint: Carefully sum each distinct part of cycle time.
After assessing the load growth curve, a project manager decided to set an optimal loading capacity that ensures the loading rate does not drop below 75%. If the maximum payload is 25 m3, what should the manager aim for as a safe loading limit?
💡 Hint: Calculate using percentages.
