PROBLEM TO BE SOLVED: To provide a multiple single-line cableway capable of adding and always keeping uniform tension to each of the four ropes of an inside loop and an outside loop composing a round-trip path, and enabling further safe traveling of a carrying apparatus. SOLUTION: The multiple single-line cableway winding one tugging rope 4 between a driving pulley 3 and a stretching pulley 1 in a double-loop shape. The duplex single-track cableway winds one tugging rope 4 between a driving pulley 4 and a stretching pulley 1 in a double-loop shape.The stretching pulley 1 is arrranged on a truck 15 directly connected to a streching/driving device 2. The streching pulley 1 is composed of a first pulley 11 and a second pulley 12 turning the outsideloop 4A of the round-trip path while sandwiching that with the driving pulley 3, and third pulley 13 arranged on a second truck 16 and turning the inside loop $B of the round-trip path while sandwitching with a driving pulley 2, and a second truck guiding pulley 14 arranged with coaxially with the third pulley 13 and turning the outside loop 4A between the first pulley 11 and the second pulley 12; and a second truck guiding pulley 14 arranged coaxially with the third pulley 13, and turning the outside loop 4A between the first pulley 11 and the second pulley 12.
