U-shaped kalan

U-shaped mine clamps are used to secure U-shaped arches, ensuring stable connections between the frames and enhancing overall support strength. Common specifications correspond to U25, U29, and U36 steel types. The inner diameter of the clamps is adapted to the cross-sectional dimensions of the U-shaped arches, with bolt diameters of 20 - 24mm. The material is often Q235 or alloy steel, treated with hot-dip galvanization for rust prevention. By tightening the nuts, it can effectively prevent frame displacement and enhance the reliability of roadway support.
