Universal clamp for lifting of a large variety of different shaped steel, ranging from steel plates and structured steel to curved and spherical shaped steels. Features: ¥ Can lift, hang, turn over and pull steel structures ¥ This clamp is equipped with a screw cam (spherical universal designed), which provides an extra powerful clamping force on the work piece at no load and even when vibrations occur during operation. The clamping force increases in proportion to the weight of the load. ¥ The main body is made from the die-forging of special alloy steels in one piece, which is optimally tempered for maximum strength and durability. ¥ High-frequency quenching of special alloy steels gives greater durability to the cam. ¥ The main body is a baked-on finished. ¥ The cam and the pad can be easily replaced.
