To calculate the job performance of a dump truck knowing the top 10 variables to determine the duty cycle, these are: (1) distance transport, (2) Dump load speed, (3) Tipper no load speed, (4) time for the loading of trucks, (5) Tipper discharge time (6) time for other maneuvers, (7) hopper capacity, (8) density of the material to be transported, (9) factor haulage Hopper [the value of tables is 85%] (10) hours of actual work. The application performs the calculations and returns five results: (1) Total time required by the cycle, (2) number of cycles per working day, (3) Total production in the working day in m3, (4) Total production working hours in tonnes.
