There's a cross-bar that hangs between the tracks, specifically to support a jack for lifting. Need a piece of wood with a metal plate to sit on the jack screw and spread the weight cross the lift point. But there's only one as part of the lift assembly. I haven't lifted mine while up on lift, but if I did, I would probably use a regular floor jack with a 4x4 and 2x6 to extend my reach, 'cause the car sits about 16" high on the lift.
Alternatively, just leave the lift flat and slide a regular jack under and lift.
I have mine flat, but on 2x4's under the tracks (so that the front stand pivot pin mount doesn't dig into the garage floor), and then, because the flat ramp sits about 5" above the floor) have 2x10 ramps (with aluminum end clips as used on ramps for pickup loading of mowers, cycles, etc) to get car up on flat ramps. Gives me enough room under to change oil, check things, etc.:idea:
FWIW.
