Growing international trading increased cargo transportation in containers, therefore the port cranes have higher loads. Increased cargo flows can influence transportation safety. It is therefore necessary to review the crane systems and determine what factors might influence the volatility of the container and its cargo during transportation. The paper includes consideration and analysis of crane control systems and related problems. The authors consider the reasons of problems, probable damage and solution methods. The paper also provides the analysis of the relationship between different container cargoes and container oscillations occurring during handling operations using a container crane prototype. The analysis of the effect of different cargoes in containers on loading process and the results of occurring oscillations are presented. Didėjant tarpžemyninei prekybai, išaugo krovinių gabenimas jūriniais konteineriais, todėl uoste esantiems kranams tenka didesnis transportavimo krūvis. Padidėję krovinių srautai daro įtaką transportavimo saugumui, todėl reikia apžvelgti krano sistemas ir nustatyti, kokie veiksniai gali daryti įtaką konteinerio svyravimams transportavimo metu. Šiame darbe yra nagrinėjamos ir analizuojamos konteinerinių kranų valdymo sistemos ir su jomis susijusios problemos. Autoriai nagrinėja problemų priežastis, galimą žalą ir sprendimui taikomus metodus. Straipsnyje pateikiama ryšio tarp skirtingų konteinerio krovinių ir svyravimų, atsirandančių krovos darbų metu, analizė, naudojant konteinerinio krano prototipą. Darbe taip pat pateikiami svyravimų analizės rezultatai, įvertinant skirtingų konteineryje esančių krovinių įtaką krovos procesui.
