The invention relates to cable saddles capable of moving transversely suitable for three slideways. The top of a tower is provided with three transverse moving slideways with cable saddles; the cable saddles comprise two first cable saddle longitudinal beams and two second cable saddle longitudinal beams; the adjacent ends of the first cable saddle longitudinal beams and the second cable saddle longitudinal beams on the same side are connected with each other through a hinge pin; the first cable saddle longitudinal beams are fixed with each other by a longitudinal beam connection system, and the second cable saddle longitudinal beams are fixed with each other by the longitudinal beam connection system; a rigging steering device is arranged at the other end (of the first cable saddle longitudinal beam) symmetrical to the adjacent end; and a longitudinal bridge direction limiting block is arranged on the bottom surfaces of the first cable saddle longitudinal beam and the second cable saddle longitudinal beam respectively. According to the invention, the cable saddle longitudinal beam is divided into the first cable saddle longitudinal beams and the second cable saddle longitudinal beams in the longitudinal bridge direction, and the two parts are in hinge joint through a hinge pin; in the hoisting process of a cable crane, the vertical force born by the cable saddles is uniformly transferred to the three slideways and the tower through the cable saddle longitudinal beams, the unclear stress and non-uniform distribution of the three slideways are avoided, the structural simplification of the slideways and the tower is facilitated, and the requirement on the slideway manufacturing precision is reduced..
