Demountable Ifor Williams

Howdy, we have been on the look-out for a second hand Ifor Williams DP120 demountable trailer but have been waiting for one with the optional dropsides. We have only seen one for sale with these but it was the 10ft model and we'd like a 14 footer - can anyone tell me why almost no-one orders these when buying new, are they rubbish or do people realise, like I probably should, that the box will never come off anyway? Thanks.

And do you like the wheels under the livestock body, some don't as they tend to snake at speed, apparently?

I don't mind the wheels underneath, you gain 6 inches inside but the tyres have a habit of going egg shaped. If I was to buy again I think I would go wheels outside and it can be unstable with cattle in. It says in the handbook if loaded not to exceed 25 mph.

We had a 14’ ‘demountable’ IW at home, as it might be handy sometimes. I think we only ever had the top off twice, as it was less bother to borrow a flat bed from elsewhere.
On top of that, it ate tyres (see post above about ‘eggs’) and snaked horribly from 45-50mph unless you checked tyre pressures were all equal before every journey.

Moving up here and having to source a new trailer, I opted for a 14’ stock trailer with wheels on the outside. If I need a flatbed (very rare), I can hire one locally for £30/day. Trailer tows better & safer, and has only had one tyre in 7 years (as a result of a brake locking on).
 
I have a 120 and sometimes take the top off (20 mins with the loader) to carry the mini digger. I've found that for doing tractor work at Mrs Fred's stables, it is easier to drive the little B250 into the cattle box after having remembered to take the exhaust pipe out, rather than take off the top or drive the modern tractor all the way there, 13 miles. It works very well and I drive it up the cattle ramp to load it.
I've never had a problem carrying cattle with the little wheels although I don't go on the motorway. As long as it is loaded properly with the partition, it has always felt OK and it has done 20 years now.
Wish I had ordered the side hinges though, as it would make it even more useful.

I’ve two 120s twin axle and tri axle which I leave the deck down permanently I personally wouldn’t buy a trailer with the wheels outside the extra width makes such a difference to the amount of stock that can go in them. Never found them hard on tyres have burst a few needlessly though . Between the two trailers they are on my Jeep for 20000 miles per year!!

We have a 14' dp120. Came with sides, ladder rack, ramps. Most importantly, proper demount stands. Highly recommended to take it off on concrete to make it easier to put back on. Take off maybe 3/4 times a year. No big job. Can't justify another flatbed for occasional use, so this fits the bill.
Tyres, important to keep up near 90lbs. Follows well, as long as cattle well partitioned. Nice going through town by parked cars, as trailer same width as Disco.
While waiting for trailer to be delivered, borrowed a Graham Edwards tried axle. That was so wide, was scary passing cars in town. :eek:Didn't like at all. Love the Ifor (y)

I had the same predicament, I hadn't enough work to justify two separate trailers so thought a DP would be the ideal solution. Like yourself I had doubts if it would work or not. I arranged with a dealer to get one for a couple of days to get one and see how I got on with it. I took it home loosened the bolts and tried to take them out of the holes and that was as far as I went with it. I left it back and bought a 12x 5' 6" flatbed with sides. I already had a cattle trailer but it is worn out at this stage.

I still like the idea of the DP trailer and would have one if IW came up with a better way of attaching and lining up the demountable top to the trailer. The bolts would be hard to line up if things were out of line.
Get one out for a day and take the top of and on to see how you get on
 
I find the only problem with the bolts is the two in the middle, as the long sides can flex a bit. I have a length of wood I slide across inside and it prises the sides apart enough to get the bolts in.
I had a puncture this week with a load of cattle on board, and the first warning was the fact that the ramp hook wouldn't close as the whole trailer had flexed over to that side.

there is a tool that Ifor williams usualy supply with the demount kit, that hooks into the rib hoops and helps align. It also has a slot to leaver the bolts out when disassembling.
