into hole until nut and
washer contact base.
Clean hole.

NOTE: If more than 2 horse shoe shims are used at any of
the column anchor bolts, pack non-shrink grout under the
unsupported area of the column base. Insure shims are held
tightly between the baseplate and floor after torquing anchors.
Step 7: Concrete and Anchoring: Concrete shall have a
compression strength of at least 3,000 PSI and a typical slab
thickness of 5-1/2” to 6”. In order to achieve required anchor
loads, a minimum concrete thickness of 4-1/4” and anchor
embedment of 3-1/4” is required at each anchor location. When
using the standard supplied 3/4” x 5-1/2” lg. anchors, if the top
of the anchor exceeds 2-1/4” above the floor grade, you DO
NOT have enough embedment.
Drill 3/4” dia. holes in concrete floor using holes in column
base plate as a guide. See Figures above for hole depth, hole
spacing, and edge distance requirements.
PUSH COLUMNS UP TIGHT AGAINST RUB
BLOCKS BEFORE DRILLING OR ANCHORING LIFT COLUMNS.
DO NOT install on asphalt or other similar
unstable surfaces. Columns are supported only by anchors in
floor.
Using the horse shoe shims provided, shim
each column base until each column is plumb. If one column
has to be elevated to match the plane of the other column, full
size base shim plates should be used. Recheck columns for
plumb.
PUSH COLUMNS UP TIGHT AGAINST RUB
BLOCKS BEFORE DRILLING OR ANCHORING LIFT COLUMNS.
Tighten anchor bolts to an installation torque of 110 ft-lbs. Shim
thickness MUST NOT exceed 1/2” when using the 5-1/2” long
anchors provided with the lift. Adjust the column extensions
plumb.
If anchors do not tighten to 110 ft-lbs. installation torque,
replace concrete under each column base with a 4’ x 4’ x 6”
thick 3000 PSI minimum concrete pad keyed under and flush
with the top of existing floor. Let concrete cure before installing
lifts and anchors.
