The present invention provides a connection structure of a super-strength steel joint inhaul cable and a roll-on roll-off ship elevator which belongs to the technical field of rope pulling. The steel joint inhaul cable is provided with a structure as follows: one end of a wire rope is connected with a steel pressed joint with a screw; the screw is provided with two nuts used for adjusting the tension of the wire rope; and the other end of the wire rope is connected with a wedge joint. The steel joint inhaul cable is connected with an elevator in a way as follows: one end of the steel pressed joint with the screw which is provided with the nut is fixed on a deck steel clapboard of the elevator, and the wedge joint is fixed on an ear plate of a cabin bottom steel clapboard. The steel joint inhaul cable is fixed, the elevator deck is raised and dropped by the rising and the descending of an oil cylinder, the steel joint inhaul cable is fixed and positioned integrally, and the elevating work is finished by every cable passing nine pulley blocks. The steel joint inhaul cable ensures the elevating structure is more compact, more reasonable and more convenient for changing and the work efficiency is increased.
