In this paper, the task was to make the calculations of the superheater transport construction. Boiler plants and their main elements are described in the introduction. Boilers can be divided into two main groups: steam generators and hot water boilers. The forms of energy that occur during the heat transfer are enumerated. Some examples where a boiler plant is used are also shown. The construction of the heater and its elements are shown, and it is explained why it needs a transport construction. The transport structure is also shown, its elements are shown and their role is described. Technical drawings of the heater and the transport construction with all the details are presented. In the software NX 12, a geometric model of the heater and transport construction with all components was created. Before the calculation, the load values were determined. The reaction forces in the lugs, the forces in the crane ropes and the weight of the load itself were calculated. The construction calculation was made in the Tower 8 software. All the loads are set, the material and cross-section of the beams are determined, and the construction is limited in such a way that the supports of the construction simulate the lugs, i.e. the places where the construction is hanged from the crane. The calculation was made very quickly and the diagrams of internal moments and forces of all beams are shown. Diagrams of displacement of individual beams of the construction are shown. Welded and bolted joints were also calculated analytically, and the dimensions of the lugs were checked.
