Today, construction machines are used in many sectors such as agriculture, infrastructure, superstructure, construction, mining and industry. Looking at the sectors in which they are used, it is seen that these machines are directly or indirectly involved in all areas of human life [1]. Heavy construction machines use much more power than standard vehicles due to their usage areas. Consequently, they consume a lot of fuel. In order to ensure fuel efficiency, reduce CO2 emissions and greenhouse gas emissions, efforts to lighten vehicles have been carried out [2-4]. Different methods are being tried to reduce weight in vehicles. As one of these methods, materials with high strength are used instead of standard materials [5]. In this context, a weight reduction study was carried out with the use of ultra high strength steel (UHSS) in the boom element of Çukurova 885 model backhoe loader. High-strength steel is a type of material with the same density but higher strength as the structural steel (St52) used in the production of construction equipment. Within the scope of the this study, on Ansys Space Claim the total weight of the machine was reduced by reducing the size of the boom element. Also on the model, UHSS was used instead of the structural steel. Then, the structural static analysis of the new model was performed with Ansys Workbench software using the finite element method. The results obtained were compared with the analysis results of the reference model in its current state (structural steel was used), and stress and deformation values were examined. The analysis results are presented by comparing the total deformation, equivalent stress and factor of safety values of two different materials. The results showed that the values obtained when using UHSS material have higher safety factor than the values obtained by using structural steel. It was understood that the weight of the boom element decreased siginificantly by UHSS material was used. A considerable fuel savings are achieved when weight is reduced in heavy-duty machines, which consume much more power than standard vehicles due to their usage areas. As a result of this study, it is also seen that lower fuel consumption and less emissions occur by reduced boom weight with respect to fuel consumption literature.
