Crane will take a fair bit of payload off the trailer as well. Third axle loses about 70 kg off the payload too. I know people say tri axles tow better but there's nothing wrong with tandem axle trailers loaded properly.

I just think a Tri axle would be better with a permanently loaded crane at the front
If you went for a centre mounted crane and had it set up purely as a mobile crane then it would make little difference
The other advantage of a Tri axle that often seems overlooked is there are 2 more tyres in contact with the floor that 30% extra friction on the ground when the breaks are applied

Regardless of axles an empty ifor trailer with a hiab mounted on the front will be way over any recommended hitch load in any case.

do it as well as you can,but learn to do it better
I don't think the cranes quite big enough either tbh but thought it would be a good example and tbh thought with gus's skills building one wouldn't be out of the question
Even starting with a brand new ifor cranes that size arnt expensive second hand often less than a grand for something that needs some work or there is this https://www.ebay.co.uk/itm/223931990080. That looks ready to go
Plus the petrol powerpack parts come in less than the 7.5 tonners above
And the labour to do the work would be outweighed by the running cost of the lorry so probably only a year or 2 before building the trailer becomes the cheaper option
by the time you spend a large wedge on the Ifor and find a decent Hiab to suit, which'll not be cheap (that example's start bid is £3.5k ) your're gonna be well up in the wonga stakes .... could run a 'cheapo' , older 7.5 for a long time, for the cost of putting a trailer together, which'd always be a compromise AND you'd have to keep hold of the damned thing ... as said major pikie magnet :mad:
I'd rather be trundling around in a comfy 7.5, kitted for the task, when I needed it, than wrestling a damned great Ifor/crane combi behind me van ... would also be a pretty fair DVSA/plod magnet too, I'd imagine. :unsure:
with the mileage / usage Gus'd give the truck, he'd also probably be able to negotiate a much more attractive maintenance/inspection regime than the usual six weeklies, for a truck doing hundreds/thousands of miles between six weeklies .... mine was on 4 monthly .... did very limited local mileage and used once or twice a week ;) ... much like Gus's planned usage

was my first thoughts ... unless the trailer was specifically built to accommodate a crane (y)

in a straight line ........ tri-axle trailer also pushes the drawing vehicle around a lot .... and takes some keeping under control in certain circumstances
plus they eat tyres on anything but straight-ish main roads

And they take a lot more manoeuvring in a tight spot

If you’re not fussy on make you can get a fair bit of kit for less than the cost of a new IW trailer!

Would a 3.5t transit double cab be an option? Could take rear seats out and fit toolbox etc. Either tow the compressor or carry on the back? Obviously more expensive and harder to keep it from being stolen but no o-license.

Gus'd never wear the Sed Ax out :giggle: ... but over the 7.5t:cry:

I like the idea of a 3.5t vehicle set up for the job, I’m a Nissan Cabstar fan but insert your favourite vehicle here!, fit an oversized crane and a nice tool box. A 3.5t short wheelbase truck should yield enough payload for that setup, as it’s doesn’t need a carrying payload as such. It’s a mini mobile crane really. The Cabstar can then tow 3.5t if needed, as it’s 7t train weight, so could tow a road compressor or a trailer with compressor on and other equipment and still have a load capacity if needed.

My take on it anyway.

certainly a neat solution James (y).... my only concern would be stability :oops::unsure:.... unless the vehicle was actually 3.5t with the set up .... which'd equate to about the same as the crane was intended for on a 7.5 ;)

sensibly done, on a subframe with stabilisers of some sort, I can see it working. It’s a bespoke solution for a specific job, it's never going to lift big loads at huge reach, but it will be that ‘extra hand‘ that I can see Gus must struggle for at times doing those big undercarraige jobs. The kind of setup I’m thinking of would be highly manoeuvrable, so could be lifting close to the machine as much as possible if the loads were heavy, and I’d also imagine it would be pushing the 3.5t limit with all tools ect.

agreed ... it'd certainly be a lot better than a trailer mounted jobbie AND be more stable (y)

As another option would it be economical to hire a small spider or picks and carry crane in for the jobs or one of those green tracked machines

I don't know what is available up there but down here there is a company that has a wide variety of little cranes available really quite cheaply

My opinion for what it is worth!

Stick to your original plan for a 7.5ton truck. Forget the trailer option, listen to V8, it will be a ball ache towing it about and manoeuvring it on site. As for which make, listening to Rory! I ran a MAN 18 tonner for something like 12 years with very little work outside of servicing. Again as V8 said, limited mileage means you are allowed to stretch the inspections.

Gotta be another £150 on the job though hasn't it?
