Ah, that answers something I was wondering about that the article didn't answer, which is how you can lift a car by its tyres without starting already under the tyre and without friction or forcing them to rotate.

Looks like the answer is (at least for this older system), come in from both sides of the tyre with two separate arms, and have each of those arms have their own little wheels on, so as you move inwards it lifts up the tyre and just rolls your mini wheels a little bit. Clever.
