Evaluation of the Economic Efficiency of Bridge Cranes
Abstract: The article analyzes the influence of various indicators on the economic efficiency of bridge cranes. The correlation modeling method was used to estimate the cost of bridge cranes. Analytical dependences describing the theoretical regression lines of the cost of bridge cranes on their load capacity in the form of linear, power and quadratic functions, as well as a parabolic polynomial of the 3rd degree are determined. It is established that the square trinomial describes the statistical relationship between the cost and the lifting capacity of cranes with a sufficiently high approximation. Annual economic effects for bridge cranes KM-12.5, KM-16, KM-20/5, KM-32/5 and KM-50/12.5 are analyzed. The greatest economic effect was at the crane KM-50/12.5. It is established that the most significant impact on the increase in the economic effect of the crane is its productivity, as well as current costs have an equally important impact.
