they slide right under low cars like this Corvette,
and with this tiny Honda generator that is so quiet,
powering this hydraulic mechanism
controlled by the hand held corded remote, it raises the car up enough to change tires, adjust suspension, etc. Even puts enough space under that car that you can put safety floor stands under the car too if you need to slide under with a creeper.
I'm very impressed. Once raised it clicks into slots in the jacks, preventing a drop if loss of power or hydraulics, and you must give it a little bit of a lift to release those clicked in locks, and then it lowers
