The article is especially critical of the electric winches that they
say are only speed controlled. They said they tried to talk to the
manufacturer (in Germany), but they refused to discuss the issue. They
also mention hydro winches some of which have the same set up - only
speed controlled - at least that's how I understood the article - and
some Diesels. Though they mention that some set ups do have both a
speed and tension indicators - sort of a hybrid.

It is clear that they implied that gasoline driven winches with
automatic transmissions, which are widespread, are the safest ones and
explain the theory as to why, namely because they are tension
controlled. I'm just the messenger.................

I remember reading about winches with torque converters, I think the
Tosts - which is a component of the automatic transmission, so not
speed controlled, but torque regulated via the transmission =
controlling tension on the cable, not the drum or cable speed.

Point is, primarily speed controlled or regulated winches are the most
dangerous type in the statistics table they produced in the article.
