The invention provides a constructional engineering lifting device moving on a rail. The constructional engineering lifting device is used for lifting large building stone (100) and comprises a machine frame (1), a cavity (101) formed in the machine frame (1), a lifting motor (2) arranged at the bottom of the cavity (101), a drive threaded sleeve (3) connected with an output shaft of the lifting motor (2), a drive threaded rod (4), a lifting base (5), a fixed base (6) and a lifting lever (8), wherein the drive threaded rod (4) is arranged in the drive threaded sleeve (3) and connected with the drive threaded sleeve (3) in a thread fit mode; the lifting base (5) is arranged on the top of the drive threaded rod (4), the fixed base (6) is disposed on the lifting base (5), and the lifting lever (8) is arranged on the fixed base (6). The fixed base (6) is further provided with a movable hinge (7) which is used for fixing the lifting lever (8) and allows rotation of the lifting lever (8).
