Zusammenfassung:The utility model discloses bridge girder rotation complete equipment. According to the bridge girder rotation complete equipment, a bridge girder pier body is arranged on the bottom surface of a main girder, the lower portion of the bridge girder pier body is hinged to a foundation through a spherical hinge, two sets of haulage cables are symmetrically wound around the bridge girder pier body, a leading-out end of each haulage cable is connected with a center-penetrating lifting jack, each center-penetrating lifting jack is fixed to a counter-force seat at the top of the foundation, and positions, provided with the haulage cables in a wound mode, of the bridge girder pier body are each provided with a haulage carding device. The inner end of each haulage cable is anchored inside the bridge girder pier body through an anchorage device, and the part, located inside the bridge girder pier body and close to the outer wall, of each haulage cable is separated from the bridge girder pier body through a corrugated pipe. By means of the bridge girder rotation complete equipment, each stranded wire in a stranded wire harness is uniform in stress in the rotation construction process of a bridge girder by bundling and carding the stranded wires, thread synchronization is achieved when the stranded wires penetrate through the center-penetrating lifting jacks, and therefore rotation operation of the bridge girder is achieved, and rotation speed and efficiency are improved.
