If the hydraulic things BON and John are talking about are like this picture, then they're an accident waiting to happen.
I have used this one to get bikes without centre stands vertical and 'up a bit', but as John says, risky as hell. It's a more-than-one-man job safely to get a machine moored as it depends hugely on the shape of the lower frame rails, plus whether there are any projections underneath that get in the way, and where the balance point is. Can't be used without straps, preferably 4 off and attached to solid points on the floor, not to the jack's frame, while someone else is holding the machine steady.
Mine has mostly gathered dust as can be seen, and I sure as hell wouldn't recommend it. A tool of last resort that should carry serious health warnings! Winchi things far safer if a suitable beam is available . . .
