INSTALLATION PROCESS FOR ELEVATOR

PROBLEM TO BE SOLVED: To provide an installation process for elevators capable of efficiently installing an elevator without adusting the length of a rope. SOLUTION: In this installation process, a value is determined by subtracting an amount of elongation of a rope from a value obtained by adding a distance from the uppermost floor-platform floor 5a to the floor 4a of a temporarily fixed car to a counter clearance H, and a counterweight 3 is lifted while an amount equivalent to the calculated value is measured upward from the upper face of a buffer 2. Thus, the lifting position of the counterweight 3 can be determined with high accuracy.
