In the final major degrees project was investigated the efficiency of loading equipment working in cargo terminals. In the beginning of project was simulated the methodology of loading equipment efficiency investigation and using it were analyzed container and metal store as terminal activity. Loading equipment working in container terminal were investigated using the theory of massive service. Also in the project were used economical and quantitative methods of management for detailed known of investigation object. In the investigation time of company AB “Lietuvos geležinkeliai“ were checked the few last years data of results in reloading works. Also in the project was investigated metal stores as cargo terminal modernization expedience, which was reasoned by calculations of productivity and according it was formulated the investment project for cranes and were given suggestions and conclusions. The main purposes of this project were to create methodology of loading equipment efficiency investigation and to analyze the expedience of loading equipment working in some Lithuanian metal stores.
