Ifor William Trailer and new winch

Post  lynnr on Wed 12 Feb 2014, 2:11 am

Hi All

Just in case you maybe interested. I am designing and building a new winch mount for my Ifor Williams LM104 trailer.
I started last night with the production of the winch plate within Solidworks. So once the rest of the mount is designed if anyone wants a set of drawings just let me know.

The design will be capable of either bolt together or weld. It will use standard steel sections so no fancy cutting or fitting needed.

The winch I am using is a Warrior ATV3500. But mounting plates of different hole pitch can be designed in. I have a Optima Yellow Top battery for the winch and I plan mounting the battery within the winch mount for neatness and security. Cut off switch will be mounted in the frame as well.

Hi Lynn

How have you got on with the warrior winch, would you recommend it? I need to fit a winch and it is a good place to start.

Also how about the battery, does it hold its charge ok? do you just take it off to charge?

Thanks for your help

Hi Simon

The winch is first class. Does everything it needs to do without struggling. It is also small in form. I have taken the solenoid box off the motor and put it inside the A frame under the battery. So only 2 wires go up to motor and I now have a cover on the winch with only the fairlead open. No rain or crud in winch while driving or stationary. Control is by an optional extra addon of wireless remote. Allows easy out spool on power and good control while winching Crystal backwards up the ramps in to her pram. I also sometimes use to pull the wagons up as well if the ramps are wet, or the wagon extra heavy.  The winch drum has a small diameter and the gearing is good to keep a slow wire speed and is auto braked so no roll back what so ever.

The battery is doing very well. I have installed a gray towing socket to charge battery while driving. During rally season the battery stays put. Only ever gets charged when going to and from events. Mind my closest event is 110 miles each way! If not using for an extended time I stick a mains charger, C-tek MSX5, on the battery and it keeps it in tip top condition as you can leave on all the time.

The larger battery in the garage for the driveway winch also has the C-tek on it basically all the time except during winch use. Big warn 9800 bolted down in the back of the garage to winch Crystal up the drive when out of steam. About a 1:7 ish slope and over 50ft long. Also used to winch the iffor trailer up as well.

Helpful as ever thanks Lynn. Will order one straight away, what size battery did you go for?

One other question -do you get on ok with the winch centrally mounted and putting the engine on one side and the trailers on the other?

Much appreciated
Simon

Hi

Battery from Here

Winch from Here

I use a pulley block from Here.






This is attached to the cargo track embedded in the trailer.







She is the other way round now but you get the idea.

This keeps the wire on the winch center line so does a good spool when pulling Crystal up with the offset. I use the closest tow point to the trailer center line when rigged up, Crystal goes on backwards now. Better balance with everything else and get more space at the front of the trailer as the engine sits further to the back, the front of the canopy is 2" of the rear cover. Using the engine front tow hitch with bottle screws and chain to secure.

Brilliant thanks - that 48ah battery is that the one you bought?

I would strongly recommend a nylon winch rope: much safer to use. I have also found the radio control for the winch a boon.  I use the winch to pull the trailer back into its parked position at home via a snatch block and loop set into the floor at the back.

Interesting - what makes it safer?

What size battery do you have Tim

It doesn't store energy like a wire rope and spools much better. Not sure on battery, but probably 48Ah. I use a solar panel to keep it topped up. The Warrior winch would probably work well on an aircraft carrier.

Thanks Tim, that makes sense, I was looking at a solar panel to keep it topped up, do you have just the panel ? I was wondering if I needed a controller?

Do you think the Warrior winch is too big then?

The main concern with winch wire is if it breaks the steel wire holds a lot of potential energy when under load and synthetic does not. So IF it was to snap the wire will backlash and MIGHT cause injury. Synthetic basically drops dead with little rope causing injury. But your load is still heading south either way.

I am use to wire and it behaviour. Yes I have had a winch wire singing under load during a demonstration. The wire was then cut by a shaped charge to get a backlash in to "analogue" legs. Quite serious injury.

if you are loading quite high then you would drop a coat or blanket over the wire and if very long winch pull a couple or more. This will kill the potential energy very effectively upon catastrophic cable failure.

The forces on a cable pulling the engine up in to the trailer are very much within the lower 30% of the max safe working load. Also remember it is up a slope but has little rolling resistance. Yes synthetic has over double the SWL per diameter but has to be handled with more care. Strand chaffing is more problematic also contamination like being spooled wet or getting wet causing mould to form, problematic to health by airborne spores. Yes wire will corrode but can be proofed by lubrication. Both will wear out and require changing at some point. If in doubt - replace.

It's a debate that has and will go on for years.

Golden rule. Treat ALL winch activity with respect and instill safe practice. Mitigate possible risk. Like during the "heavy" portion of winching up in to th trailer. I am outside at the side of the trailer diagonally opposite the winch wire with the engine and the heavy tarpaulin side and trailer side panels are between us as well. When the engine is rear wheel crested I do move inside to steer but the loads at that point are a fraction of the peak. I can push the wire to the floor or sideways by hand easily. And there is less than 4ft of wire off spool.

It's up to you.

The little ATV 3500 winch is for on the trailer.
My battery is the one shown directly from the link. It also powers other things while camping.

Hi Lynn

Hope you're well.

I'm looking to buy a trailer and wondered what your trailer bed size is. It seems the LM104 may have been discontinued as its not in the catalogue and I can't find the tech spec on line

Many thanks

Rob.

Hi Rob. 

Think you want this link. LM105 still on the books. 


http://www.iwt.co.uk/products/flatbed/lt-and-lm/?tab=spec#tab

10x5.5ft twin axial. Spring for the 8ft Aluminium ramps as makes loading so much easier. Angles etc.

Thanks Lynn I suspected that would be the one. New car gets delivered in two weeks then I'll get it ordered.

Thanks also for the info on the ramps, was going for the galv steel, but will change to the Alu

Oh forgot. 
Put an electric winch on with wireless remote. Hand crank is ok but a lot of work if by yourself.
