Abstract: A universal beam clamp for supportably engaging the top flange of an I-beam comprises a pair of opposed symmetrical clamp elements each including a base having an elongated inwardly opening slot along its inner edge. A support plate is mounted upon the base along its edge, there being aligned elongated first and second slots centrally of the support plate. An adjusting screw with separate right and left hand threads extends through the first slots. A nut is mounted on each of the threads outwardly of the support plate and is engageable therewith. A nut retainer upon the support plate prevents rotation of the nut. Rotation of the screw in one direction simultaneously moves the clamp elements inwardly and rotation of the screw in the opposite direction simultaneously moves the support plates outwardly. A support interconnecting the support plates has a base projected through the seconds slots and an apex adapted for connection to a crane operated lift hook.
