The invention relates to an over-tractor, which comprises two individual bodyindividual bodies symmetrically connected to form a whole. The individual body comprises a connecting plate and a fixing plate. The two ends of the fixing plate are respectively provided with connecting plates. The inner side edge of the fixing plate is provided with an arc-shaped groove, and the arc-shaped surface of thearc-shaped groove is an inclined surface whose center is inclined outward. The connecting plate is provided with a wire rope fixing part; Through the invention, the purpose of less traction can be achieved, the design conductor slack in construction is ensured, the working efficiency is improved, the deformation of the iron tower and the frame caused by the traction is reduced, and the operationsafety is enhanced.
