Wanted to share my flush-with-the-floor lift install from a few years back.
Of course it helped that my house is built on the side of a hill allowing for a 6 ft tall crawlspace under the garage.
Had my contractor cut cement, build a frame and supports underneath then pour cement leaving a hole for the air line.
I ran hoses underneath from my compressor over to and under the lift and then another 2 ft over for the foot control.
