Terry, quite true, but confounding the matter are makers like the company
who built mine. They used a heavy-duty large trailer winch as the guts of
our hoist. Found that out digging in the website for specs and maintenance
tips on it, and found nothing on the entire unit, but found plenty on the
metal cable winch it uses.

Subject: T&T: Boom Winch / Hoist
This might be a good time to consider the differences between 'winches' and
'hoists'. They pretty much look the same, and we all tend to use the words
interchangeably, but they're different. Winches are designed to pull and are
rated for max pulling capacity. They almost always include a free spooling
capability. Hoists are designed to lift and lower and are rated for safe
working loads. They do not have a free spooling clutch, as this would be
unsafe in a vertical lifting situation. They are also equipped with a more
substantial brake for protection from abrupt loading and long duty cycles.
Most have some sort of load limiting to prevent overstraining the mechanism.
Net/net...if you want to save money, a winch will provide the power, whether
it is ac, dc or armstrong (the boat trailer winch). If you want safety (and
reasonable line speed) you probably want a hoist.
