[TowerTalk] Maasdam "Powr Pull"

[Rick Karlquist]

A question for you come along experts.

I saw some come alongs at the Chinese tool store (you know the one)
that claimed to pull some huge weight like 8 tons.  Assuming
the user applies 40 lbs, this is a 400:1 mechanical advantage,
not counting friction.  This is hard to believe.  Is this
true of these or even the American equivalents?  Or is this
specsmanship where it moves an 8 ton boat onto a trailer
or something like that?
