The invention provides a freight transport cableway hanger for transmission lines, and belongs to the technical field of the construction of transmission lines. The hanger is suitable for engineering freight transport ropeways for the transmission lines, and can prevent ropes from dropping effectively by adjusting angles with the ground at complex terrains to reduce engineering accidents caused by the dropped ropes. The hanger mainly comprises a hanger body, an end plate which is perpendicular to the hanger body, a hanging plate, an adjustable bolt, a rope support saddle and a rope support wheel, wherein a sliding chute is formed on the end plate; the hanging plate can slide along the sliding chute of the end plate by the adjustment of the adjustable bolt; and the hanging plate of the hanger is connected with the ropeway support by a pin shaft. The hanger has an adjustable function, and when the ropes of a ropeway meet intersection angles at the support, the hanger can regulate the position of the hanging plate, so that the hanger is perpendicular to the ground without external assistance. Simultaneously, the hanger has can swing with the ropes of the ropeway slightly, so that rope dropping accidents are avoided.
