I also have a battery on my trailer. It charges off the vehicle as soon as the trailer is plugged in.

On our truck we run a piece of welding lead from the battery to the back of the truck. From there we use a female welding plug. On the trailer we use the male plug that goes with it and simply plug them together and we have our 12 volts to the winch and no battery to mess with simply crank up truck when winching car up if you want half the time we forget to crank it. One nite dumazz here forget to cut truck back off we watched the rest of the races with truck merrily idling away. I ain"t as sharp as I once was LOL.

The math posed is good but it is not for a rolling load. We had a 3500 lb winch on ours and when it went down we used a 1500 lb ATV winch on for several races and it never had an issue just a little slower. We pulled up a 2450lb late model and in a pinch I had to use it to pull a 1994 suburban up on an open trailer and is pulled it right up.
I worked on a guys car that had 2 of the ATV winches in the trailer and the cable was in a U between them with a block with a pulley. He did it for under $300 and for the reason if one went out he would not be dead in the water, the other would still pull the car up and then he could replace the one that stopped working later when he could.Last edited by Egoracing; 04-17-2013, 07:22 AM.

That's all fine in well. With the rolling load calculations mine should pull 11k up my rampovers. Here is the problem with this. With my friend's 1500# winch pulling it up a 20% grade it should be able to pull close to 5,000# which is double the weight of the car. The problem? It didn't pull it up there well. I've used my winch to pull a 4500# truck onto my old trailer and it did it with some straining. Going back to my original statement. A Honda Accord can pull a 9,000# load, slowly, but I would rather have a Dodge or Ford Diesel instead. Not because it will pull it but because it was BUILT for it.
Plus the difference between a 1500# winch and a 3500 or 4500 may be what, $100? I bet if I invented a spark plug that was $200 each that gave 10 more HP folks would jump to buy it over the $9 plug they put in now.Last edited by merc123; 04-17-2013, 09:37 AM.Web: http://www.t17.co

There are many things that stop a winch from working properly, Wire size and distance form the power source are a major factor. If it was not installed or wired right you will have problems no matter what winch you use. I never extend any leads on the winch and if they bolt on I keep them as short as possible and NEVER use the smallest wire that is called for. I have seen a 15,000 lb winch have issues pulling up a 3200lb ministock on a verl low trailer, he had it wired to the battery in the truck using 2 sets of jumper cables and about 10' of wire on each cable. We put a battery on the trailer and used about 12 inches of 2/0 high strand copper cable to connect it and it would load the car so much faster he used a pull block to slow it down so he could control it from outside the car.Originally posted by merc123 View PostThat's all fine in well.

I have a Rule 6000lbs and it great.
Something to consider while shopping for el cheapo China made junk in winches is the line speed and load holding brake. Instead of using bigger more powerful motors to increase the rated power it's easier to raise the gear ratio to get the torque needed for pulling but now the line speed is way down. For example the HF special has a line speed of 6 feet per minute. If you have a 20 foot trailer your pushing that button for over three minutes of just standing there to get your car on the trailer! Time holding the button may not add up to much when time loading the car doesn't matter however it's another example of piss poor quality. A load holding brake and free wheel clutch are handy to have as well. You wouldn't want a winch spooling out the load when you let go of the button to move the jack, tools, or something of the like out of the way.
