Are you asking about the optimal cycle time for dump trucks in relation to an excavator's digging flow? If so, the cycle time depends on several factors: 1.Excavator Digging Speed– How quickly the excavator can fill a truck. 2.Dump Truck Capacity – Larger trucks take longer to fill but reduce trips. 3.Haul Distance & Road Conditions – Longer or rougher routes increase cycle time. 4.Dumping Efficiency – Time spent unloading and returning. 5.Number of Trucks – More trucks reduce excavator idle time but require coordination. A well-balanced system ensures the excavator is never waiting for a truck, and trucks are not idling excessively. Do you need help optimizing a specific operation?
