The utility model relates to an electric power overhaul ladder. An insulating vertical column is arranged at the center of the upper plane of a base; the top end of the insulating vertical column is connected with the lower surface of a main body through a pin hole; a fin is arranged on the lower surface of the base; the insulating vertical column is connected with the circular base through a rotating disc; a plurality of articulating holes are uniformly formed in the peripheral direction of the base; the articulating holes are connected with the tail end of the main body; a plurality of pedals are uniformly distributed on the upper surface of the main body; a sliding chute is formed in one side surface of the main body; a fixed pulley A is arranged at the tip end of the sliding chute; a stayguy connected with a sliding block is arranged on the fixed pulley A; a hook is connected with the tail end of the sliding block; a fixed pulley B and a handwheel are arranged on the main body above the fixed pulley A. The electric power overhaul ladder has the advantages that the direction of the overhaul ladder body can be changed by turning the vertical column, meanwhile the supporting stability of the overhaul ladder is improved through the supporting of the base and the insulating vertical column, the pressure on a cable is effectively reduced, when other tools are required, the only thing to do is to pull the stayguy, then tools on the hook can be pulled up, and the labor intensity of maintenance personnel is reduced.
