I don't think the top piece on a two-post lift is technically a "support". Realize all lifts flex. The stanchions could easily fail fore, in for aft if improperly designed, manufactured, installed or used. I'd rather they flex then fail. Watch any large aircraft wing on takeoff; they flex a huge amount during rotation for takeoff. On shorter two-post lifts like my DW, the hydraulic lines and cable that connects the lifting mechanisms run on the floor between the stanchions. On taller stanchion lifts, those mechanics can be run from above. My two-post is rated for 9K pounds, and when I lift any vehicle, I use four jacks under the lift points for support and added safety.
