Four post lift jack question

Most consumer lifts that have trolley jacks have them that ride on the deck surface.

Note also that they ride on the diamond plate.

Commercial lifts generally have jacks that ride in a channel or the lip of the channel.

That channel is not even present on the consumer lifts.

Seems like you could still design a roller or bearing to ride on the flange rather than the top but allow the top to make contact under stress.

Challenge is to keep the gap small to avoid bending the deck.
