OPERATIONAL COSTS OF EARTHMOVING MACHINERY

COSTES DE OPERACION EN MAQUINARIA DE MOVIMIENTO DE TIERRAS

THIS ARTICLE DEFINES THE CALCULATION OF OPERATIONAL COSTS AND TYRE COSTS IN EARTHMOVING OPERATIONS. AMONG OPERATIONAL COSTS ARE INCLUDED CONSUMPTION COSTS (GAS-OIL, LUBRICANTS, FILTERS AND WORN PARTS) AND REPAIR COSTS. AS REGARDS TYRE COSTS, A LINEAR METHOD IS USED TO SUPPLY THE QUOTIENT BETWEEN THE TOTAL COST OF A SET OF TYRES AND ITS LIFETIME IN HOURS. GUIDELINES ARE GIVEN FOR PLOTTING A GRAPH SHOWING THE PRESENT HOURLY COST OF THE MAIN EARTHMOVING MACHINES. IN THE CONCLUSION A SIMPLE METHOD IS APPENDED FOR DERIVING THE HOURLY COSTS OF THESE MACHINES AS A FUNCTION OF THE VARIATION IN THEIR PRICES.
