The floor should be test drilled to verify minimum floor thickness and to confirm building drawings. A core sample should be
obtained and tested to verify minimum floor compressive strength. When investigating floor properties, consult building drawings
to verify proper floor reinforcement.
All 2-post lifts require a continuous single slab. Spanning expansion seams or positioning posts on separate slabs is not acceptable.
--- ALL MOHAWK LIFTS MUST BE INSTALLED ON CONCRETE ONLY ---
DO NOT install any Mohawk lift on any surface other than concrete, conforming to the minimum compressive strength, aging,
reinforcement, and thickness stated in the table above.
DO NOT install any Mohawk lift on expansion seams or on cracked or defective concrete. 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 install a Mohawk lift on hand mixed concrete.
DO NOT install any Mohawk lift on a secondary floor level or on any ground floor with a basement beneath without written
authorization from the building architect and prior consultation and approval from 02+$:./,)76//& .
If the floor does not meet these minimum pre-existing floor requirements, it is suggested to construct a slab as outlined in New Slab
Recommendations . If the location of the lift is in a seismic zone, additional provisions will need to be considered, and it is
recommended to consult a building architect or engineer.
