FOUNDATION REQUIREMENTS
Concrete shall have compression strength of at least 3,000 PSI and a minimum
thickness of 4”.
CAUTION!! DO NOT use on asphalt or similar unstable surfaces.
SPECIAL NOTE
This Lift does not require bolting to the floor
(BUT)
If you choose the option to anchor the Lift to the floor please follow the
detailed instructions and criteria below.
FOUNDATION and ANCHORING REQUIREMENTS
1. Concrete shall have compression strength of at least 3,000 PSI and a minimum
thickness of 4” in order to achieve a minimum anchor embedment of 3 ¼”. NOTE:
When using (¾” x 5 ½”) long anchors; if the top of the anchor exceeds 2 ¼”
above the floor grade, you DO NOT have enough embedment.
2. Maintain a 6” minimum distance from any slab edge or seam. Hole to hole
spacing should be a minimum 6 ½” in any direction. Hole depth should be a
minimum of 4”.
3. Shim each column base as required 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. Torque anchors to 85 ft-lbs. Shim thickness MUST NOT
exceed ½” when using the 5 ½” long anchors with the lift. Adjust the column
extensions plumb.
4. If anchors do not tighten to 85 ft-lbs. installation torque, replace the concrete
under each column base with a 4’ x 4’ x 6” thick 3,000 PSI minimum concrete pad
keyed under and flush with the top of existing floor. Allow concrete to cure
before installing lifts and anchors (typically 2 to 3 weeks).
