Determinación de costos y rendimientos de maquinaria para la elaboración de chips en la empresa aglomerados Cotopaxi.

Abstract

The aim was to determine the costs and yields of machinery for the production of chips in Aglomerados of Cotopaxi company. The study used a Completely Randomized Block Design (CBLD), with two factors (type of load and time), where the treatments were four (Chipper + Trineumatic, Chipper + Manual, Chipper + Backhoe and Chipper + Crane) with 3 replications (December, January and February) per treatment. The factors affecting yields in the production of wood chips were determined, these being environmental and extrinsic factors, human and the mechanical factor of the machinery. The highest volume without chipping was obtained with the backhoe and 154.31 and a lower volume with the crane of 108.56 m³, a chipped volume of 25 m³ was achieved with the crane, lower fuel consumption of 36.10 L when using the crane, lower number of operators for the backhoe and crane of 3, 00 for each, lower feed consumption of 2.07 for the crane operator, longer working time of 0.04 h for the manual, 1.81 m³ of chipping directly to the truck when using the traction truck and a lower delay time of 0.04 h with the backhoe. The lowest cost recorded was determined for T1 (Chipper + Pneumatic Trencher), reaching a value of $9,281.47. It was concluded that the best cost for the elaboration of wood chips will benefit a lot when using the T1. Therefore, it is recommended to use T1 (Chipper + Trineumático) since, according to the results obtained, it is expected to obtain better yields in the production of wood chips at a lower cost.
