The invention discloses a lifting device with an upper limiting sensor and a lower limiting sensor for construction projects. The lifting device is used for lifting large-scale building stones (100). The lifting device comprises a machine frame (1), a cavity (101) arranged in the machine frame (1), a lifting motor (2) arranged at the bottom of the cavity (101), a driving threaded sleeve (3) connected with an output shaft of the lifting motor (2), a driving threaded rod (4) arranged in the driving threaded sleeve (3) and connected with the driving threaded sleeve (3) in a threaded fit mode, a lifting base (5) arranged at the top of the driving threaded rod (4), a fixed base (6) arranged on the lifting base (5), and a lifting lever (8) arranged on the fixed base (6). The fixed base (6) is further provided with a movable hinge (7) used for fixing the lifting lever (8) and allowing the lifting lever (8) to rotate.
