This utility model discloses a leveling device for pre-embedded outriggers of a tower crane, relating to the field of tower crane technology. It includes a top plate, a reinforcing plate below the top plate, and a leveling block above the top plate. A threaded rod is threadedly connected to the middle of the reinforcing plate. The threaded rod, connected to the reinforcing plate, allows for vertical displacement. This movement of the threaded rod moves the leveling block, which in turn moves the bearing plate, thereby adjusting the level of the tower crane's outriggers. This prevents overturning accidents caused by excessive outrigger leveling errors and resulting in non-compliance with verticality requirements. Two limiting plates, through limiting holes, restrict the movement of the leveling block and bearing plate, allowing them to move only horizontally. This leveling device has a reasonable structural design, is easy to adjust, and is more convenient to use.
