5) The anchor bolts must be installed at least 8”
from any crack, edge, or expansion joint.
6) Use a concrete hammer drill with a 3/4 inch
carbide bit. Tip diameter should conform to ANSI
Standard B94.12-1977 (.775 to .787). Do not use
excessively worn bits or bits which have been
incorrectly sharpened. A core bit may be
necessary if an obstruction is encountered.
Never substitute with shorter anchor.
7) Recheck “Inside of Columns” dimension (
Fig. 1
).
Drill the anchor holes using the base plate as a
template. Drill through the floor if possible or to a
depth of 5 inches minimum.
Complete steps 8 thru 11 for the six (6) exposed
anchors around each column, then raise the
carriages. Repeat steps 8 thru 11 for the two (2)
anchors under each carriage.
8) Vacuum dust from the hole for proper holding
power.
9) Shim both columns to plumb using the shims
provided as shown in
Fig. 3
. DO NOT shim more
than 1/2" at any given point. Use a level no less
than 24” in length to plumb columns.
10) Assemble washer and nut to anchor with nut just
below impact section of bolt. Drive anchor into
hole until nut and washer contact base.

11) Tighten power column anchors and recheck
column for plumb. Re-shim if necessary. Torque
to 150 foot pounds to set anchors.

12) Before raising overhead into position install 4
each (2 per column) hex flange bolts and nuts in
bottom hole of column extension
(see Fig. 4
Installation Aid)
for temporary support of
overhead. Lift overhead assembly up into
position and install with 8 each (4 per column)
3/8”-16 x 3/4” lg. hex flange bolts and hex flange
nuts per side as shown in
Fig. 4
.

Overhead Assembly
13) Check idler column shimming. Use additional
shims (
see Fig. 3
) to remove any gaps that may
have been created while installing overhead
beam. Tighten anchor bolts and re-check column
for plumb. Torque to 150 foot pounds.
14) Install Overhead Limit Switch to the Overhead
Beam using the rear set of holes on the Power
Side of the lift.
