Powering an 80% efficient hydraulic thing with an electric motor that runs at 80-95% efficenct. Or run the 80-95% efficient motor electrically directly... Adding conversions always decreases efficiency.Hmmm... I'm just thinking out loud, feel free to tell me to stop... I like thinking outside the box. Maybe a 12V hydraulic pump and hydraulic winch would use less power than an electric winch?

What would your usage be? What are you going to anchor a 20K winch to that you don't end up just dragging your truck towards the "stuck" thing you're trying to pull out? Or, vise-versa, if it's your truck that's stuck, what are you going to be able to tie off to as an anchor that you won't end up just pulling it towards your "stuck" truck? Or pulling the tree (or whatever) over?
You're not going to be able to just toss the cable end with the hook on it to any passing motorist to loop around their receiver hitch. You'll end up just dragging them to you.
We ran some big winches on our heavy wrecker recovery rigs. But they had 3 axles with parking (air) brakes, and hydraulically powered anchors that could be driven into the ground to keep the wrecker planted where we wanted it.
Even then, you wonder how long before wire melt on a 450 AMP draw?yea man, you need the engine running any time you use them, these are not a battery only item, duty cycle can be as low as 15%, i know my HF 12k gets hot even with a light load on it.
I have a 10K on our Jeep Rubicon. Has come in handy a few times.Just keeping a cheap winch out of the elements helps keep them working great. I have owned a cheap 9k milemarker for about 25yrs..because its kept out of the elements.
thats full stall speed single wrap on the drum, my HF pulls nowhere near its max load, (althought I have nothing in the 12k range)Even then, you wonder how long before wire melt on a 450 AMP draw?
It sounds obvious I know, but in order to get yourself unstuck, the other end of that winch cable has to go somewhere. You've got to figure out both "ends" of that scenario. If you're stuck in a field (lets say), winch cable in hand, what are you connecting to that can withstand that much force being pulled against it? I can see you needing to pull out your truck with a fully loaded hay trailer from a muddy field. That part makes total sense. So yeah, a 20K winch would be useful for that purpose.Ummm…..yeah that’s obvious. I was thinking I’d use it for getting myself unstuck when one of my farm tractors isn’t around. Also possibly pulling out other stuck equipment, which happens a few times per year.
Anchoring my truck to a “passing motorist” was never in the thought process.
Nice!
