Summary: | The invention discloses an elevator position reference system and a method for monitoring settlement of a building by using the elevator position reference system. The elevator position reference system (3) comprises a hoistway (4) extending in a vertical direction. The system comprises: a first position measuring band (8a) extending vertically along a portion of the hoistway (4); and an upper tensioning device (10) connected to an upper end (20a) of the first position measuring tape (8a) so as to apply a tensioning force (30) in an upward vertical direction. The lower end (22a) of the first position measuring belt (8a) is fixed in the hoistway (4). The system comprises: a second position measuring band (8b) extending vertically along at least some of said portions of the hoistway (4); and a lower tensioning device (12) connected to the lower end (22b) of the second position measuring tape (8b) so as to apply a tensioning force (32) in a downward vertical direction. And the upper end (20b) of the second posit |
