This electric pole installation device has a chain 11 having the length possible to be wound around the electric pole D, a retaining device 12 for retaining the chains at the desired height by mutually connecting them at one part of the outer periphery of the electric pole, and a bar-shaped member 13 supported at the chains in such a posture that the member extends outward to the outer periphery surface of the electric pole. A footing 35 having the rigidity possible to withstand the load of the worker is disposed on the chain side of the bar-shaped member, and a hook portion 36 having the rigidity possible to withstand the articles load is disposed at the outside of the footing. A circulating part for circulating in a direction crossing with the extending direction is formed on the top end 36a of the hook part.
