    Jul 16, 2020 · So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation. In our example, Wb = Lb = 5 and Wt = Lt = 15, so Ab = 5 * 5 = 25 and At = 15 * 15 = 225, and D = 5. Therefore, the volume is: = 542 cf or 20.0 cy.

  • Ground pressure | Tractor & Construction Plant Wiki | Fandom

    Ground pressure is the pressure exerted on the ground by the tires or tracks of a motorized vehicle, and is one measure of its potential mobility, especially over soft ground. Ground pressure is measured in pascals (Pa) which corresponds to the EES unit of pounds per square inch (psi). Average ground pressure can be calculated using the standard formula for average pressure: P = F/A. In an

  • Prediction of remaining useful life (RUL) of Komatsu

    Jul 15, 2020 · It is an essential task to estimate the remaining useful life (RUL) of machinery in the mining sector aimed at ensuring the production and the customer's satisfaction. In this study, a conceptual framework was used to determine the RUL under the reliability analysis in a frailty model. The proposed framework was implemented on a Komatsu PC-1250 excavator from the Sungun copper mine.

  • Bucket Fill Factors | Cat | Caterpillar

    Bucket Fill Factors. Fill Factor is the percentage of an available volume in a hauler body, bucket or bowl that is actually used. For example, a fill factor of 87 percent for a hauler body means that 13 percent of the rated volume is not being used to carry material. Buckets often have fill factors over 100 percent.
