Change in load depending on degree of lifting by ship's crane

U ovome radu je proračunata sila podizanja tereta brodske dizalice u ovisnosti o kutu dizanja, a gdje je maksimalni kut na koji dizalica podiže teret 75,52 stupnjeva. U prvom poglavlju opisana je zadana dizalica s pripadajućim slikama. U drugom poglavlju prikazan je proračun radijusa podizanja grane te maksimalna težina podizanja pri određenom kutu dizanja, hod klipa te volumen punjenja. Rad sadrži i odnosne dijagrame. F1-R-Fmax dijagram se odnosi na silu podizanja grane u odnosu na promjenu kuta dizanja tereta. h-dijagram prikazuje dužinu izvlačenja hidrauličkog cilindar u odnosu na promjenu kuta podizanja tereta. V-dijagram opisuje korelaciju između volumena punjenja cilindra i kuta dizanja tereta. Dijagrami su dobiveni na osnovu proračuna iz zadatka.In this paper it was required to calculate the lifting force of ship's crane according to angle of lifting. The maximum angle to which crane can lift load is 75,52 degrees. First chapter decsribes crane with belonging pictures. Second chapter presents calculation of lifting radius, maximum lifting weight at a certain degree of lifting, piston stroke travel and a filling volume of a cylinder. Paper also includes flow diagrams. F1-R-Fmax diagram shows how cranes lifting force relates to different lifting degrees. h-diagram shows how draw lenght of a hydraulic cylinder relates to different lifting degrees. V-diagram describes correlation between filling volume of a cylinder and an angle which the load is being lifted at
