The invention provides a heavy-load type aligning carrier roller. The heavy-load type aligning carrier roller comprises an upper transverse beam and a lower transverse beam made of a high-strength metal material, the upper transverse beam is placed at the upper end of the lower transverse beam, the upper transverse beam is equally divided into three sections, auxiliary rotating devices are arranged on the inner sides of the lower ends of the sections, on the left side and the right side, of the upper transverse beam, a main supporting device is arranged in the middle of the lower end of the section, in the middle, of the upper transverse beam, the lower end of the main supporting device and the lower ends of the auxiliary rotating devices are connected with the lower transverse beam, friction rollers are arranged on the sections, on the left side and the right side, of the upper transverse beam, a common roller is arranged on the section, in the middle, of the upper transverse beam, and bolt fixing holes are formed in the left side wall and the right side wall of the lower transverse beam. The lower transverse beam is made of the high-strength metal material, so that the rigidity is improved, moreover, the two auxiliary rotating devices are arranged, so that the rigidity of the upper transverse beam during rotation is improved, the aligning effect during heavy load is also greatly improved, and the reliable operation of equipment is ensured.
