New Slab Recommendations:
The information contained in this appendage supercedes any other information given in the
accompanied manual. This information is presented for design recommendations for a new concrete slab in the
event that the pre-existing floor does not meet minimum requirements of the applicable lift type. Please read all
instructions below carefully before producing new slab.
Basic Concrete Requirements:
Minimum Tensile Strength of Concrete: 4,000 P.S.I.
Minimum Aging of New Concrete Slab: 28 days (cure time)
Minimum Thickness of Concrete Slab: See New Slab Table & Figure Attached
Minimum Width and Length of Slab: See New Slab Table & Figure Attached
All properties of the new concrete slab are mandatory and must conform to the above stated properties
before installation of the lift is deemed acceptable. The new slab must be totally surrounded by an existing
concrete floor. Certified strength documentation should be obtained from the firm who supplies the concrete
mixture at the time of the pour.
The slab above is designed as “stand alone” and does not take into account the contribution of strength
from surrounding concrete. It may be desirable to reinforce the new slab to the pre-existing surrounding floor.
Care should be taken to locate these specific reinforcement bars away from any anchor positions of the specific
lift.
This new slab design does not account for second floor installations or installations in a ground floor
with a basement beneath. For this case, the lift should not be installed without written authorization from the
building architect.
All ¾ inch diameter anchors must be a minimum of 6 inches away from any expansion seams, control
joints or other inconsistencies in the concrete. All 1 inch diameter anchors must be a minimum of 7 ½ inches
away from any expansion seams, control joints or other inconsistencies in the concrete. Refer to anchor
manufacturer specifications for specific information concerning edge distances and bolt to bolt distance
requirements.
NEVER, NEVER, hand mix your own concrete.
