You might want to check the height under the gantry. I need 13 ft. to get a van up.
Drill a hole to find concrete thickness.
Where I didn't have sufficient footprint thickness, instructions recommended a 4 ft. piece of sufficient size angle iron welded alongside footpad, to spread load, - 20+ yrs, lotsa different vehicles, no drama .
Worked at a shop and used a 12k lift that had those extensions. They were about 4ft long and built in from the factory with the same thick steel as the floor plates. Very good idea for lifting heavy trucks ect.
