The invention discloses a hanging method of a pole-climbing-free optical cable hook hanging device. The hanging method comprises the steps that an optical cable hook is fixed into an operation groove and limited by the limiting block; an operation handle of an operation block is pressed, so that the operation block slides to the top end of a special-shaped groove straight line part; an optical cable is arranged in the middle of the optical cable hook and then moved towards a steel strand used for fixing the optical cable through an insulating rod; one end of the optical cable hook is hung on the steel strand, and the insulating rod is rotated by 50 degrees to 65 degrees, so that a guiding hook of an operation head is also hung on the steel strand; the insulating rod is further rotated in the same direction, a rotation block drives the operation block to move in the direction opposite to the rotation direction of the insulating rod, the operation handle slides to a hook part along a special-shaped groove, the operation block is bounced upwards to enable the other end of the optical cable hook to be hung on the steel strand, the insulating rod is rotated by 25 degrees to 35 degrees in the opposite direction and then pulled downwards, and the optical cable hook hanging process is completed. The hanging method has the advantages that hanging is convenient, the efficiency is high, the cost is low, and the security coefficient is high.
