Electric winch

Hi

I'm going to fit an electric winch for recovering the rib onto the trailer
Nos can tell you why

Winch sorted I think unless you can tell me otherwise

http://www.winchsolutions.co.uk/winc...wspecheet5.htm

But with only 12 m of cable as you lose 18% of the pull with every turn on the drum (I wanted to go for the rope but have been advised not to )

To power it I was going to fit a very large battery in the back of the truck and charge it from the caravan plug on the tow hitch so it has a full charge when ever I need it. The caravan plug is powered through a relay and I would fit a fuse on the battery.

Anything else needed

James

It should be fine for the job. I put 12,000 lb on mine but I also use it for pulling out trees etc - I have never had any problems pulling my boat onto the trailer, even when the cable is almost fully wound. If you are finding it is not enough, you can always block and tackle it to double or treble the pull - just be carefull you don't bend the chassis!

Unless you are concerned about your truck batteries, is there any reason why you do not wire it into the main battery? If you keep the engine running while you are winching it should not cause any problems.

One other hint, put a tow witch on the front bumper, not sure what you use for towing but a front mounted winch is more useful and does not get in the way of the boot / take out knees in quite the same way.

I had a quick look at their web site, but I couldn't see any mention of :-
a) freespooling clutch (pull the wire/ rope out by hand)
b) line speed

If the line speed is 6ft per minute, then it is going to take a long time to get the rope out to the rib and then a long time to haul it in - so worth checking !

Just re-read your post and realised that you are probably planning to fit the winch to the trailer. If so, ignore my previous comment.

I doubt that your alternator will cope with a 260A load for very long (many of them are only rated at 65A) - this is why many 4x4 winch configurations have a dedicated battery which is not connected to the alternator during winching operations (the battery is charged later via a split charge relay). This of course may be an urban myth put about by split charge manufacturers since I can't see why jump starting another car (400-600A) would not blow up the alternator !

Not an expert by any means, and I have mine mounted on a Defender which maybe has more of an alternator, but I only have one battery, and have used it to winch oak trees up a 30 metre bank and have had it running quite hard for reasonably extended periods - no problems as a result. Probably find it will all go horribly wrong next time though!

As you type, the wee little gremlins will be nibbling away at the electrics...

Yes the idea is to fit the winch to the trailer and have the battery in the back of the pickup.

I'll find out about the line speed

Make sure you get a real good deep cycle battery , ya wont regret it

Maybe an Ultima or an opima.They make the job a lot easier

Unloaded line speed is 30 ft/min which will drop with a load
