This study shows the results of safety analysis obtained from the three different wire rope connections in the RPSD (Rope Platform Screen Door) system, which are the rope connected at both ends, the ropes connected by a pulley at both ends, and the ropes connected by many pulleys at both ends. With a constant load applied, the displacements in the ropes connected by a pulley at both ends and the ropes connected by many pulleys at both ends are smaller than that in the rope connected at both ends. There are no any special different displacements between the ropes connected by a pulley at both ends and the ropes connected by many pulleys at both ends. The displacement in the wire rope diameter of 6mm is smallest of 4.83mm and the strains from the displacements in the ropes connected by a pulley at both ends and the ropes connected by many pulleys at both ends are very small.
