The invention discloses a pulling trailer for a small tower crane. The pulling trailer comprises a trailer skeleton, steering front wheels, driven rear wheels, pulling oil cylinder installation positions and tower body hinging points, wherein the tower body hinging points are positioned on the rear part of the trailer skeleton; the pulling oil cylinder installation positions are positioned below the middle of the trailer skeleton; one pair of supporting components which are in parallel with the trailer skeleton extends from the rear of the trailer skeleton for supporting; each supporting component comprises a supporting frame and a supporting point; and the supporting point is positioned behind the tower body hinging point. The pulling trailer has the beneficial effects that the pulling trailer has a compact structure, a reasonable space layout and a small floor area, is flexible to operate, can quickly finish the one-time pulling installation of a tower body and a main component carried on the tower body, can be disassembled and flatly placed in one time so as to be converted into a transportation working condition, and carries parts of tower crane accessory devices to realize transfer transportation. A workload generated when the tower crane is installed, disassembled and transported can be greatly reduced, working efficiency is higher, and requirements on additional auxiliary installation equipment are greatly reduced.
