Here is a progression of photos taken during a recent vertical platform lift (wheelchair lift) installation near Boston. It’s a 4′ Savaria Multilift -which in this case will do the same job as a 40+ foot long aluminum ramp (the alternative solution).
It’s a pretty typical installation. We usually need to excavate a site for a concrete pad strong enough to support the lift, install a retaining wall, and almost always have to raise the porch or deck height to the entry door threshold height (removing ALL of the steps from the path of travel).
