Serapid is the other one. Both Gala and Serapid are "holeless" systems. Both can work in 30" usually, and perhaps a tiny
bit less in some circumstances.
(30" being pit or sub-pit floor to lift floor at lowest
level.)
@Mtnbiker226 Keep in mind the GALA Spira-lifts are TRULY GREAT products (Used world wide by the likes of Disney) and they truly can be installed without the need to drill down to bedrock and / or through the water table.
The 'BUT' to keep in mind is:
Whether your lift requires one varying height supporting column, two, three, four, six or eight columns (due to square footage, weight requirements, static and / or live loads). Each supporting column amounts to '
POINT' loading: Your ~400-ish square
foot lift may be capable of being supported by as few as 3 varying height columns but each of those columns is effectively reducing its share of the load to an area of approximately four square feet ( 2' x 2').
From the perspective of the lift's manufacturer; no problem, they'd have made certain their lifts were MORE than capable of handling your loads.
The REALLY BIG BUT is: How is the floor below your lift constructed?
Is the (basement or whatever) floor constructed to support your amount of square footage with your amount of weight on as little as four x 4 square
foot "points".
All's well and good UNTIL your lifts sink into your improperly constructed floor and effectively bore their own wells down to, and below, your area's water table.
An engineer's stamp of approval for your floor's ability to handle / survive the appreciable
point loading is something you REALLY want to have in
hand BEFORE you issue the
Purchase Order for your GALA lifts AND their installation.
GALA manufacture, and warranty, great products: Have you got the floor and underpinning to support them??
Forewarned is four armed (or maybe even five or six armed)
