The utility model discloses an inhaul cable pay-off platform for cable-stayed bridge construction, which comprises a base, a first vertical plate is welded and fixed on one end side of the upper surface of the base, the joint of the two first vertical plates is rotatably connected with a rolling shaft through a bearing, and an inhaul cable main body is wound on the outer surface of the rolling shaft. A motor is mounted at the end part of the winding shaft and positioned on the side surface of the first vertical plate; by designing an inner tooth groove in the end part of the winding shaft and designing a tooth pressing plate in the inner tooth groove, the end part of the inhaul cable main body can be embedded into the inner tooth groove, a wrench is clamped on the surface of a rotating head to drive a screw rod to rotate in situ, and a moving head is driven to move on the outer surface of the screw rod when the screw rod rotates in situ; when the moving head moves, the tooth pressing plate is easily driven to
