IMPORTANT: NEW CONCRETE MUST BE ADEQUATELY CURED AT LEAST
30 DAYS MINIMUM. NO LIABILITY FOR ANY DAMAGES WILL BE ACCEPTED
SHOULD YOU INSTALL THE LIFT ON AN UNSUITABLE FLOOR.
4.3 IMPORTANT CONCRETE AND ANCHORING INFORMATION
1. Concrete shall have compression strength of at least 3,000 PSI and a minimum thickness
of 6”. Measure the length of the supplied anchor bolts in order to achieve a minimum anchor
embedment of 3 1/4”. If the top of the anchor exceeds 2” above the floor grade, you DO NOT
have enough embedment.
2. Before drilling 3/4” dia. holes in concrete floor using holes in column base plate as guide,
make sure the hole distance from the edge is not less than 6”. Hole to hole spacing should
not be less than 6 1/2” in any direction. Concrete thickness should be a minimum of 6”.
3.
DANGER:
DO NOT Install on asphalt or other similar unstable surface. Columns
are supported only by anchoring in floor.
4. 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 (Reference
Shim Kit). Torque anchors to 150 ft-lbs. Shim thickness MUST NOT exceed 1/2”. Adjust the
column extensions plumb.
5. If anchors do not tighten to 150 ft-lbs. installation torque, replace 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. Let concrete cure at least 30 days before installing lifts and
anchors.
