Wiring winch to trailer - 3rd battery?

[Danielle]

What are you using for a winch?
I just have a harbor freight 12k with a group 31 right next to it. Never have had any problem with not enough battery.

I have the harbor freight 18k winch and a marine battery.

I'm going to see if I can hook battery to the power wire and a trickle charger on the power circuit in the trailer

(Tune in in 2029 when I post that I have actually done this hahahaha)

I wonder what that winch draws? I have no experience with that winch, but my experience with big winches. (16k warn) is that they draw more amps, even with no load, and they are slow, meaning they draw more for longer to do the same work as the smaller winch.......but the bigger one can pull harder of needed.

Winches draw more power under load and even more power if heavily loaded. The power draw is totally dependent on the load. More load = more power draw.

Yes, my point was is that in my experience, bigger winches pulling a load that a smaller winch is capable of, draw more than the smaller winch doing so. And almost always are slower, meaning they are drawing more over a longer time to do the same work.

I also think next time I'm going to add a pulley into the mix and see what happens. I feel like all roads for me end up at simple machines, which I appreciate for my simple brain

Put a pulley on the car and end of my cable back up by winch at top of trailer

I will need to do this soon. If the used IP doesn't get this bus moving, I'll have to drag it out of way of the office trailer my dad is taking off my property

If no one dies, I'll try to video it to show what I mean

going back to reread, buuuut
@Danielle
it is called a snatch block aka double line pull.
I am going to go grab an extrication 101 from the archived stuff I had bookmarked....

If you are killing marine deep cycle units , 2 thoughts
1 you are not recharging the system as you drain it. (read pulling without the alternator running)
2 they are too small
3 the wiring into said winch has high resistance (any hot surfaces?)

This is just a boilerplate from Warn.

Everybody feel free to chime in on this suggestion...but, if it was me and I had a dead skid steer to drag onto a trailer...what would be wrong with bringing along a bucket of sand and/or oil-dry to throw under the tires to allow you to drag it up on the trailer ?

That was the first thing to come to mind for me, but I have done goofball stuff before...

Whatchallthink...??

Roll-back guys do this. But they use wd-40. A couple of squirts where the tires go and it makes it pretty slippery.
