The utility model relates to a tail skidding device for a hoisting Fischer-Tropsch reactor of a 6400-ton hydraulic compound crane, and belongs to the field of machineries. The tail skidding device comprises a steel framed structure, wherein the steel framed structure comprises two towers and a main beam; each tower comprises a base, standard knots and a top knot device; the multiple overlapped standard knots are arranged between the base and the top knot device; a flexible hinge is mounted on the top knot device, and is hinged to the main beam; the main beam is connected between the two towers to form a portal structure; lifting devices are mounted on the main beam, and are used for hoisting weights; each lifting device comprises a lifter base, a lifter and a steel strand guiding frame; the lifter base is used for supporting the lifter; the lower surface of the lifter base is in contact with the upper surface of the main beam; a cable mechanism is arranged on the lifting device. The tail skidding device solves the problem of crash between a pipe orifice and a crane hoisting appliance in the hoisting process, and avoids the phenomenon that a steel strand of a main lifting lug diverges from the security angle in the dragging and skidding process.
