PROBLEM TO BE SOLVED: To provide a processing method capable of reducing labor and time for processing a groove formed on a guide pulley.SOLUTION: A first roll-up rope is removed from a first groove of a guide pulley 11 around which the first roll-up rope is wound. After removing the first roll-up rope from the first groove, a traction sheave 10 is driven for rotating the guide pulley 11, and a processing apparatus 12 processes the first groove of the guide pulley 11. Then, a second roll-up rope wound around a second groove of the guide pulley 11 is moved to the first groove, and the second roll-up rope is wound around the first groove. After winding the second roll-up rope around the first groove, the traction sheave 10 is driven for rotating the guide pulley 11, and the processing apparatus 12 processes the second groove of the guide pulley 11. |
