Creating a project for the power supply, control and protection of a PLC-controlled bridge crane

V diplomski nalogi sem se osredotočil na izdelavo projekta za napajanje, vodenje in zaščito PLK vodenega mostnega dvigala. V nalogi sem navedel splošen opis nekaterih mostnih dvigal in manjše razlike med njimi. Predstavil in opisal sem osnovne elemente za vodenje in zaščito mostnih dvigal. Izdelal sem delovno shematsko vezavo in glavne segmente projekta tudi predstavil in opisal. Izdelal sem program za programirljivi logični krmilnik, ki izvaja vodenje in zaščito celotnega postrojenja za zahteve varnega in zanesljivega obratovanja mostnega dvigala.In my diploma thesis I focused on the design of power supply, control and protection of PLC-controlled bridge crane. In the thesis I provided a general description of some bridge cranes and minor differences between them. I presented and described the basic elements for guiding and protecting bridge cranes. I made a working schematic binding and also presented and described the main segments of the project. Furthermore, I have developed a program for a programmable logic controller which performs control and protection of the entire plant for the requirements of safe and reliable operation of the bridge crane
