Heavy equipment investment for contractor companies is a long-term investment that can be used in various fields, such as construction projects, mining projects, and can also be leased to other parties. Before investing in heavy equipment, a feasibility study is needed to determine whether an investment is feasible or not. The feasibility study for heavy equipment investment in this research using net present value methods. The parameter assumptions in the feasibility study can change and affect the investment feasibility, so a sensitivity analysis is needed. The sensitivity analysis in this research was carried out on the parameters of fuel prices, operating costs other than fuel costs, salvage value, and working hours of heavy equipment. Based on the results of the sensitivity analysis, it is known that the parameters of fuel prices affect the feasibility of heavy equipment investment, especially in excavator and dump trucks. Both of these equipments have the shortest fuel price sensitivity range value, which is below 60%. The working hours of equipment parameters affects the feasibility of heavy equipment investment, especially excavators. If the working hours of excavator are less than 1.715 hours per year, then excavator investment is not feasible. The operational cost parameters other than fuel cost and salvage value don’t affect the investment feasibility of heavy equipment. The results of the sensitivity analysis also show that the working hours is the most influential parameters in heavy equipment investment compared to other parameters.
