2.Tap the screw hole on the workpiece to make the lifting ring bolt installed vertically on the workpiece surface.The threaded hole should be drilled and sunk, so as to prevent the top grain from expanding when the hoisting ring is torsional.
3.The workpiece surface must be smooth, so that the lifting ring washer is in full contact with the workpiece surface, without any clearance in the middle.
4.Do not add padding between ring washer and workpiece surface;
5.After installation, the side of the hanging ring u-bolt shall not touch the suspended objects or other objects.
