The invention discloses a crane main lifting fixed type gantry hook lifting position detection device which comprises a gantry beam. A main trolley is erected on the gantry beam, a crane control device is arranged on the gantry beam and installed in an electrical room in a crane main beam, and reflecting plates are arranged in the middle of the upper surface of the gantry beam. Laser range finders are arranged on the lower surface of the belly part of the main trolley, and the laser range finders correspond to the reflecting plates and are kept perpendicular to the reflecting plates. According to the crane main lifting fixed type gantry hook lifting position detection device, the automatic detection of the lifting position of a main lifting fixed type gantry hook is realized, the height is displayed in a cab, a driver is guided to operate, manual judgment errors are reduced, automatic deceleration is realized when the gantry hook enters a specific height, shutdown is conducted immediately when the gantry hook enters a dangerous height, and the existing safety risk and equipment damage are avoided.
