Universal screw clamp for lifting and transport of steel plates and similar steel structures. Equipped with an articulated pressure plate on the spindle side and a fixed plate attached to the housing on the opposite side. This gives a very good clamping effect to what is to be lifted/transported. The shackle allows effective clamping force to be achieved in most positions. The screw clamp should not be used with steel products with a hardness above 37 HRC, or below 8.5 HRC.
