The invention discloses a specially-made underframe for a tower crane, and relates to the technical field of tower crane installation. The specially-made underframe comprises a standard underframe, two transition secondary beams and two transition primary beams, the two transition secondary beams and the two transition primary beams are arranged in parallel, and the standard underframe is installed above the two transition secondary beams. The two transition secondary beams are mounted above the two transition primary beams, and the two transition secondary beams and the two transition primary beams are distributed in a groined shape. The transition primary beams are used for being installed on a basement top plate, connecting fulcrums are formed at the connecting positions of the transition secondary beams and the transition primary beams, and the connecting fulcrums are located above a structural column in a basement. According to the specially-made underframe for the tower crane, stress on the bottom of a tower crane foundation is transmitted to a building structure column in the basement, and the overall safety of the tower crane and a building structure is met.
