The invention relates to the technical field of engineering hoisting equipment and discloses a tower crane structure with weight detection. The tower crane structure comprises a base and a tower body vertically fixed on the base, wherein a suspension arm is arranged at the top of the tower body; a weight base block and a winch are arranged at one end of the suspension arm; the other end of the suspension arm is provided with a pulley; a steel rope on the winch winds around the pulley to be connected with the suspension arm; a hook is arranged under the steel rope; a rotary table is arranged in the middle of the suspension arm and is rotationally connected with the top of the tower body; the pulley is provided with a connection shaft; the bottom of the hook is provided with a connection plate; a supporting ring is arranged at the outer end of the connection plate; a cover plate is arranged at the outer end of the supporting ring; a central hole is formed in the center of the cover plate; the outer end of the connection shaft is provided with an anti-releasing baffle; a pressure sensor is arranged between the anti-releasing baffle and the inner end of the cover plate; and the outer end of the cover plate is provided with an alarm lamp connected with the pressure sensor. The tower crane structure can be used for detecting the weight of objects in real time so that whether the tension of an object on the steel rope is in a steel rope load range or not is judged and the utilization is relatively safe.
