PROBLEM TO BE SOLVED: To provide a guide rail installation engineering method of a machine room-less elevator capable of easily installing a guide rail by reducing anchor driving work and securing prescribed elevating height by using H-steel and an upper cage return beam. SOLUTION: A guide rail 8 for a first cage and a guide rail 9 for a first weight are elevated in advance of elevating a guide rail 11 for a second weight and upper end sides of them are fixed on the upper cage return beam 5. Thereafter, the guide rail 11 for the second weight is elevated up to the top floor by an electric unloading device 20 hung on an elevating beam 22. After that, a hook 26b of a manual unloading device 26 hung on a deep side end part of the upper part turning car beam 5 is connected to the guide rail 11 for the second weight, and the guide rail 11 for the second weight is moved to a position immediate below the manual unloading device 26. Thereafter, the guide rail 11 for the second weight is elevated up to a prescribed height by the manual unloading device 26 and fixed on a wall surface of an elevator shaft 1.
