The invention discloses a multi-tower combined crane. The multi-tower combined crane comprises a tower footing, a plurality of tower bodies, a jacking mechanism, a rotary platform and an upper vehicle, the tower body consists of a plurality of standard knots; the bottoms of the tower bodies are installed on the tower base, each tower body is provided with the jacking mechanism, the top of each jacking mechanism is connected with the bottom of the rotary platform, and the upper vehicle is installed on the rotary platform. According to the multi-tower combined type crane, the multi-tower combined type tower bodies are innovatively adopted, the distance between the tower bodies is large enough, the stability is greatly enhanced, the tower bodies adopt ordinary standard knots and jacking mechanisms which are mature in technology to replace oversized standard knots and large jacking mechanisms, and transportation and installation are easier. 本发明公开了一种多塔组合式起重机，包括：塔基、若干个塔身、顶升机构、回转平台和上车；所述塔身是由若干个标准节组成；所述若干个塔身的底部安装在所述塔
