The article presents a method for calculating the technical condition of the tower crane on the basis of integrated monitoring of the mechanisms of the lifting structure using a digital model.The use of information technologies allows to take a new look at the issues of ensuring the safe operation of lifting mechanisms. Due to the application of these technologies, a qualitatively new method of calculating the technical condition of tower cranes on the basis of an integral-differential approach, which takes into account the score of defects, according to the regulatory documentation, is proposed. The concept of the technical condition index of the tower crane (TCItc), as an integral indicator reflecting the general condition of the nodes and mechanisms of the crane, is introduced. The use of information technologies to calculate the technical condition index of tower cranes makes it possible to integrate the geometric parameters of the tower crane and a mathematical algorithm for their evaluation, which results in a quantitative assessment of defects formed during the operation of tower cranes.
