This research includes a geodetic study for the rehabilitation of damaged bridge cranes axes, its reconstruction and calibration in order to invest in the production process. The beginning was devoted to studying the types of bridge cranes used in large factories, geodetic methods used in their construction, and the conditions that must be achieved by axes. Based on the previous conditions, we have proposed a geodetic method to rehabilitate cranes. Also, a computer program has been prepared to implement the proposed mechanism by (mat lab). Testing the proposed method I has been done with the program on actual examples. The program was tested in two main cases: -First: When installing bridge cranes axes, -Second: In the periodic monitoring (systematic control) for bridge cranes. The research has proved the possibility of using the proposed method in rehabilitation, installation, periodic monitoring. It also has showed the efficiency of the proposed computer program.
