Take this example: if a truck starts its first leg from Job Site A to Plant 1 and then to Job Site B, and each leg takes approximately 10 minutes, including loads and unloads, the total cycle time is 40 minutes. 9 . A short summary of this paper. TOTAL CYCLE TIME = Wait and Load + Turn and Dump + Haul Min + Return Min; PRODUCTION HOUR = 60 * Production Efficiencies / 100; CYCLES PER HOUR = Production Hour / Total Cycle Time; NO.

Some of these considerations for a dump truck, for example, according to RaNae Isaak, powertrain and TCO consultancy leader at Cummins Inc., include: federal regulation, the state laws including bridge and frost that may impact operation, the time spent off-road, the duty cycle of the vehicle, the weight of the commodity, the potential . stream This is done using the TKPH marking: Tonne . 343 0 obj <> endobj • Dump Body • Ejector Body The ejector body can now be easily removed and a dump body itted for greater machine versatility. dump truck cycle times | Learn about the transportation management system from TRUX. The operating cycle can be defined as a succession of phases or a series of basic operations. Idling time is an important factor that influences equipment productivity; however, the causes of equipment idling have not been considered in previous CV methods. Number of required trucks = truck cycle time / loading time Truck cycle time = loading time + going time + return time + dumping time Loading time = truck capacity / production rate of loader Truck capacity = 12 (loose material) / 1.12 = 10.71 m3 (bank measure) Loading time = 10.71 × 60 / 50 = 12.85 min Travel time = 16 × 2 × 60 / 20 = 96 .
