The invention provides a 12-to-1 traction structure for a heavy-load cargo ladder and relates to the technical field of heavy-load cargo ladders. The 12-to-1 traction structure comprises a car frame,a bearing assembly and a counterweight assembly. The bearing assembly is arranged above the car frame. The counterweight assembly is arranged on the left side or the right side of the car frame. A carroof diversion sheave set is arranged at the top of the car frame. A counterweight diversion sheave set is arranged at the top of the counterweight assembly. The bearing assembly comprises a tractiondevice, a steel wire rope, an upper-layer bearing structure and a lower-layer bearing structure. A car roof rope winding wheel set and a counterweight rope winding wheel set are arranged on the lower-layer bearing structure. A first rope head plate is arranged on the upper-layer bearing structure. A second rope head plate is arranged on the lower-layer bearing structure. The first end of the steel wire rope bypasses the car roof diversion sheave set and the car roof rope winding wheel set and then is connected with the first rope head plate. The second end of the steel wire rope bypasses thecounterweight diversion sheave set and the counterweight rope winding wheel set and then is connected with the second rope head plate. By the adoption of the 12-to-1 traction structure, the total weight of the heavy-load cargo ladder is dispersed in the upper layer structure and the lower layer structure, the structural stability is improved, and the good balance performance is achieved.
