What precautions should be taken with erection hardware?
Don't use bent bolts. These bolts are made of high carbon steel and thus are dangerous if bent; discard them and don't try to straighten them.
Use cut washers under all bolt heads for better bearing.
Make sure the erection bolts are long enough to penetrate completely through the coil insert.
Be certain the erection hardware is the proper size to fit the inserts being used.
If strongbacks are used, be sure they are not spliced at critical points. If there is any question contact the tilt-up detailer from the insert manufacturer.
Use grout pads under erection hardware situated on exposed aggregate surfaces. This will furnish a uniform bearing load to the slab.
Make sure the top edge lifting hardware is perpendicular to the vertical axis of the panel. If the panel has a sloping top (in the plane of the thickness) be sure the hardware is wedged to this position; otherwise, the inserts could be seriously overloaded.
See that the bales of all erection hardware are free to rotate along the line of action of load lines.
