7.6 Anchoring
Columns
The requirements for column’s square-ness and plumb must be
adhered to. Failure to do so could cause lift failure resulting in
personal injury or death.
• Use the base plate on the column as the guide, drill each hole in the
concrete approximately 6” deep with the rotary hammer drill D.19. To
assure full holding power, do not ream the hole or allow drill to wobble;
• After drilling, remove dust thoroughly from each hole using compressed air
and/or wire brush. Make certain that the column remains aligned with the
chalk line during this process;
• Assemble the washers and nuts on the anchors then tap into each hole
with a hammer until the washer rests against the base plate. Be sure that
if shimming is required that enough threads are left exposed;
• If shimming is required, insert the shims as necessary under the base plate
so that when the anchor bolts are tightened, the columns will be plumb;
• With the shims and anchor bolts in place, tighten by securing the nut to
the base. DO NOT use an impact wrench for this procedure;
• Anchor another column as outlined in above steps.
7.7 Installation Of Column Extension
• Determine the proper installation position of
the column extension (higher setting or lower
setting);
• Align the holes between the column and
the extension with screws M12X40 and the
washers D.12 as shown.
• Tighten the screws and nuts thoroughly.
7.8 Installation Of Overhead Beam
• Make sure no parts missed in the beams;
• Assemble two beams as shown. Do not tighten the screws and nuts at this
moment;
• Install the anti-crushing bar brackets on the beam using M6X16 screws and
nuts.
