They work like a "winch" too for pulling stuff. Not a lot of

before you have to stop and rejigger but if you are stuck in the

BTDT. The most useful thing I carried was a folding pruning saw to cut
a tree trunk lever to repeatedly lift the car and let rocks piled
against the tire fall into the rut, and then to cut short pieces to
make a few feet of corduroy track.

The chain fall has served me as a slow and awkward manual winch. For
horizontal pulls a lever hoist is a much better choice. The jack is
more pull for a lot less money than a big lever hoist, though.
