The invention provides a method for replacing a hoisting steel wire rope of a vertical loop. The method for replacing the hoisting steel wire rope of the vertical loop comprises the steps that firstly, a loop trolley is placed at the highest potion and is locked, the working steel wire rope is dismantled from the loop trolley and is connected with a standby steel wire rope on the top of the loop, the working steel wire rope on a drum of a hoisting device is cut off, the working steel wire rope drives the standby steel wire rope to move under the action of the gravity, and the standby steel wire rope is wound around a pulley block when the working steel wire rope falls on the bottom surface completely; secondly, the working steel wire rope and the standby steel wire rope are separated, the hoisting device is started, so that the standby steel wire rope is wound around the drum, and the standby steel wire rope stops when the length of the standby steel wire rope reaches a reserved length; the standby steel wire rope is connected with the loop trolley, and finally the loop trolley is unlocked. According to the method for replacing the hoisting steel wire rope of the vertical loop, the steel wire rope is replaced by arranging the loop trolley on the top and winding the steel wire rope through the drum of the electric hoisting device, operation is easy, the labor intensity of maintenance workers is greatly relieved, and working efficiency is improved.
