The article considers the application of geodetic methods in the operation of large industrial units on the example of rotary kiln maintenance in order to obtain data for its subsequent adjustment for the elimination of its possible deformations. For performance of works one of variants of complex Axyz (Swiss firm "Leica") has been chosen. The possibility of application of this complex is shown and the new specially developed technique for measurement of the given object is described. The technology of geodetic works on this object is considered.
