The utility model relates to a lifting device for square billet forging, which is constructed by that: two clamp arms connected with each other at their central part, whose upper ends are connected to lifting chains by joint pins and so on, and whose lower ends are connected to the localizers and clamping mechanism whose spherical end of a universal rod is connected with a clamping board through nut and a dropping proof board, wherein, the clamping board can freely move in the regulated region and can rotate and erect the billet then quickly lift it to the mold thereby shortening the transferring time and reducing the heat lost of the billet. The lifting member adopts the structure having two armatures and lengthening clamping arms, so that the billet can be lifted up by the friction which is generated by the interaction between the gravity of the billet and the clamping board without the clamping hook, therefore, claw can be avoid so as to ensure the production quality and increase the qualified rate of the forgings. The utility model can lifting the billet weight 3 to 40 T, width 500 to 2000 mm, height 200 to 1600 mm.
