Profitability analysis of reparation of the construction machinery damaged parts – how to save money

Abstract

This paper presents review and analysis of the profitability i.e. the cost effectiveness of reparation of the damaged parts in the construction machinery. The paper considers parts like loader's teeth, blades for asphalt mixing, impact beams of the rock materials crusher, blades for clearing the vegetation overgrowth, terrain-leveling knives, blades for trenching, snow ploughs blades and crushers hammers. The profitability of surfacing application was estimated based on the cost-effectiveness. Majority of the listed parts were subject of the long time studies accompanied by the corresponding experiments for checking the profitability of each of the applied surfacings, which were used to establish the optimal technology of surfacing by checking the hardness and microstructure of the executed weldings. The objective of this paper is to point to advantages of the applied technologies from the cost-effectiveness point of view.
