The guide system has vertical guides located inside the cargo hold of the ship, and each has stoppers (2), positioned at even distances. One stopper has a horizontal plate (3). The plate is turnable and longitudinally moveable along a vertical shaft (4), and is fastened near a wall (13) of a guide (1). The opposite end of the plate is located on a support arm (5) and a second wall of the guide. The plate is fixed to the arm via a vertical movement stop (6). The upward movement (L) of the plate along the shaft is longer than the active height (H) of the movement stop.
