Thanks for the pointer. What I saw was not encouraging, though...

http://tinyurl.com/y84se9 : At $130 that could almost fit into the budget,
6 kg might be bearable. The data provided was not too extensive, other than
that it is a 1 hp (750 W) motor. That is plenty for my application,
actually quite an overkill. I found a bit more data for a sister-winch:

http://tinyurl.com/upxjm : Here they have a load/speed table. I don't know
the spool diameter, but I estimated with at least 10 cm. This gives an idle
speed of max. 22 rpm -- which is too slow. Probably there are not many
winches that are much faster: I'd need it around 80 rpm, four times the
speed. 

Am I wrong with this estimation? Are there winches that rotate at 80 rpm? I
don't have a lot of experience with ATV winches.

Thanks,
Gerhard
