Problem. Geodesic work is paid special attention in the process of supervising the failures of various units of hoisting cranes. Such work is necessary at preventing accidents at industrial enterprises. The existing normative documents regulating the tolerable degree of deviation indicate: the magnitude of deviation from the straightness of the longitudinal beam of the crane bridge in the horizontal plane; difference of rail levels in any section of the crane bridge; deviation of the axis of the crane rail from the design position; deviation from the vertical plane of the running wheels of the bridge and gantry cranes; deviation of the angles of misalignment of the running wheels. Goal. In this regard, the existing tolerances are aimed at finding new developments in methods and means that allow the geometry of the cranes to be controlled. The practice of operation and especially the manufacture of lifting and transport equipment sets the task of designing and assembling fundamentally new universal means, which would provide continuous geodetic control of geometric parameters of the crane with the necessary accuracy. Results. The analysis of the existing normative documents regulating the permissible degree of deviation from the design position of hoisting equipment structures is presented in the work. The shortcomings of the considered tolerances are identified and the main tasks in this area are formulated. Originality. New methodological bases and technical means of geodetic control are proposed. The theoretical bases for improvement of geodetic control of crane equipment are presented in the work and scientific research of measurement accuracy with the new developed methods is carried out, where the laser basic fixator in combination with the universal mirror device is the reference basic geometric line. Practical value. The proposed source-light-mirror-scale complex is a convenient and inexpensive visual observation system.
