10. With the column firmly anchored, use the Base Plate as
a guide, then drill pilot holes B, C, D & E approximately 2”
deep using a rotary hammer drill and 5/8” concrete drill-bit.
11. Move the column out of the way.
12. Repeat previous steps 5 - 9 making sure the column
Base Plate remains perfectly positioned over each indi-
vidual pilot hole.
13. 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 both side to side and
front to rear. (See Fig. 6.7)
14. With the Shims and Anchor Bolts in place, tighten all
Anchor Bolts tight to the base plate . Turn 3 to 3-3/4 Turns.
DO NOT
use an impact wrench for this procedure.
(See Fig. 6.8)
NOTE:
IT WILL BE HELPFUL TO MARK ON THE
BASE PLATE OR OTHERWISE NOTE THE
LOCATION AND NUMBER OF SHIMS USED
AT EACH DROP ANCHOR LOCATION TO
ASSIST AT TIME OF REINSTALLATION.
Fig 6.7
Inspect all drop in anchors for proper setting and or
damage each time the lift is re-installed. inspect the
concrete for cracks defects and/or damage. do not rein-
stall the lift if any of the drop in anchors are defective or
the concrete is cracked or defective.
It may be necessary to shim the columns to ensure that
the columns are plumb. The columns must be plumb
and square or damage or injury may occur when using
the lift. Do not exceed 1/8’ total shim thickness when
using the supplied Drop in anchors.
