DETERMINING HEAVY EQUIPMENT FOR THE EXCAVATION AND STOCKPILING OF THE COAL HAULING ROAD DEVELOPMENT PROJECT

Abstract

The amount and time on the efficient operation of heavy equipment is the amount and duration resulting in low cost and targeted time. Thus, it is necessary to analyze the appropriate heavy equipment to achieve the most optimum alternative in terms of time and cost. This study used an analytical method involving collecting the data and calculating the productivity of heavy equipment used in constructions project. The researcher analyzed several alternatives for selecting the type of heavy equipment. Based on the results, it is shown that the amount of productivity of the tools that are used on the Excavation and Stockpiling of the Coal Hauling Road Development Project, the productivity value of the Excavator is 158,4 m3/h, Dump Truck is 180 m3/h, Bulldozer is 264,98 m3/h, Vibration Roller is 511,2 m3/h, and Motor Grader is 15660 m3/h. It can be concluded that determining the heavy equipment is recommended for the Excavation and Stockpiling of the Coal Hauling Road Development Project resulting in the alternative combination two that is included two units of Excavator, two units of Dump Truck, 1 unit of Bulldozer, 1 unit of Vibration Roller, and 1 unit Motor Grader. In contrast, alternative 2 had the most efficiency (optimum) in the amount of time and cost compared to alternatives 1 and 3.
