Abstract
This research paper offers and tests the methods of applying the electronic levelers, meant for leveling the rails under polar cranes at a Nuclear Power Plant, which ensures the required accuracy of geodetic control over polar crane tracks. The exceeded values were directly measured between the typical points of a crane track, made up of 4 (four) points ("virtual" stations), by using the precision electronic leveler Sprinter 150M and high-precision leveler Topcon DL-501. When processing the results, such main error limits were calculated: taking the readings, tilting of the rail, measuring the exceeded value present due to an angle and due to unevenness of levers at the station. The results were analyzed in comparison with the tolerances for determining an exceeded value between the diametrically opposite points of a rail track, thus confirming the reasonability and convenience of using the high-precision and precision electronic levelers.
