The paper presents a case study of gravel transshipment in RTC Luka Leget in Sremska Mitrovica, R. Serbia. Problems that led to the incorrect operation of conveyors used in the transshipment of gravel from barges to the separation plant were analyzed. They included activation the safety switch of the conveyor drive, backward movement of the material on the belt, fracture of the connection tension pulley - axle, etc. It was found that ignorance of the actual force in the conveyor belt leads to most of the problems and the need of a solution for this problem was highlighted. At the end, proposed solutions were given in order to establish the normal operation of the plant and to prevent delays in gravel transshipment.
