That's brilliant.
There's a local guy who's got a big Jap/chink 4x4 with a massive caravan that works on exactly the same principle, so still a viable and presumably (surprisingly) legal set up.

These are termed 5th wheels in Canada.  Would be great to have this on a Land Rover rather than a monster pick up!

Quite common idea
The kits are readily available
Trailer braking is an issue as you usually have to use electric braking system

Hi,

I looked up electric trailer brakes on Google. Normal in America, but I don't think it is allowed in UK.

Query does a UK Cat.B licence cover artics?  Partially super-imposed used to mean 20% of trailer weight imposed on towing vehicle. I don't know the answer, but I would find out before driving such a rig. No licence = no insurance.

These Scottish Aviation trailers have overrun brakes - nothing electric in the '60s. Interesting mechanism  but actually quite effective in good working order.. Empty the brakes do not a lot but they are so light that is not really a problem..  They were used for light bulke load transport : airplane parts, furniture, etc..

Please do not shoot me - but under EU legislation this is actually very legal with a BE licence : 7500  kg. trainweight.. Airbrakes make light work of slowing down and they are a delight to drive..



No idea what will happen when you are on your own...

Racetech use boingies with a fifth wheel to move the starting gates around at my local racecourse, and others.
I'm sure a Goooogle image search will show you one.

Yes - know them.  :thumbs:

They feature in the magazines from time to time..  However, those use a " fifth-wheel coupling" in various sizes. These Scottish Aviation ones use a 50 mm ball that is fitted onto a "spider" that sits on the load bed sides.

Well... This weekend we're doing a good old fashioned UK Raid.



2,900 kms (or 1,860 miles in your money) in 72 hrs. with a 3-axle trailer to collect the remains of the Scottish Aviation Artic Trailer, some airplane seats for the new conference rooms and a pair of radar domes to protect the satellite uplinks against the elements...

So if you see a 1.0 (Keswick Green Hard Top) on French plates with a big trailer & a rooftent - give us a  wave..

I saw a Keswick Green Land Rover today.... it pulled into my workshop yard, minus a vacuum pump bolt  *help*

It was a pleasure to meet you and Ivo today Arjan, and to show you round our collection of aeroplane bits. I wish Ivo the best of luck with restoring his trailer and I cant wait to see some photos of the airline seats in your conference room  :smilewide:
It will be touch and go, but if I can keep the Sea King under the required continental height once on its frame, I would love to bring it to a show on the continent in the future... I might have to buy shares in BP if I decide to bring it behind the Series 3 though....

Fingers crossed that our home-made banjo bolt lasts OK for the rest of your trip, so you can get all the way home under full power!

A VERY BIG THANK YOU to MATT & MIKE

A banjo bolt came undone and made some ponies run away from the engine bay corral - but you guys saved the days and we found the ponies again   :giddy:



A 2,610 kms. round trip in 73 hrs. 3 stops to load (yes, including this trailer), 3 nights sleeping in the 110 & Ivo in the Hard Shell Roof Tent, 2 ferry crossing and many stops for coffee.

... and yes : that bold is still there  :smilewide:

Many, many thanks  :thumbs:

Hi,

DVLA specify (or did) that an "artic" (eg; A trailer with 20% of it's mass, or more, super-imposed onto the tractor unit, requires a higher class driving licence. Driving without a licence to cover the vehicle you are driving, means you are driving without a licence, so your insurance is void.

So, a trailer weighing 1 ton (2240lbs) or 1 tonne (2200lbs) may have a nose weight of 448lbs, or 440lbs, respectively. I think we can assume that if you can lift the jockey wheel off the ground, without growing another pair of Adam's apples, then it ain't an articulated trailer. But on the other hand, if you had a small trailer with a short draw-bar, and loaded four 1cwt bags of sand at the front end, it might, technicallyl, well become an articulated trailer, and your licence won't cover you to pull it, so your insurance is void. Solution? Extend the length of the draw-bar ... Principle of Levers. It's probably easier to place the bags of sand over the axle, so the trailer is better balanced, less weight on the tow-ball.

I can see no reason why a draw-bar trailer can not have a "swan-neck" draw-bar, with the tractor unit having a 50mm ball  bolted to the chassis, above, or even in front of, the rear axle, so technically an articulated trailer, but not according to DVLAs definition of "20% of the trailer's mass super-imposed onto the tractor unit.  PLEASE SEEK LEGAL ADVICE BEFORE DOING THIS.

Has everybody seen the DVD of a Volkswagen Beetle performing acrobatics with an articulated traler? The tow-ball was mounted in the middle of the VW's roof, so giving a full 360 degee articulation. it looked like fun.

Please tell what you know...

Felix Catus, otherwise known as a domestic cat, is a small carnivorous mammal with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. They are predators who are most active at dawn and dusk. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. Compared to humans, they see better in the dark (they see in near total darkness) and have a better sense of smell, but poorer color vision. Cats, despite being solitary hunters, are a social species. Cat communication includes the use of vocalizations including mewing, purring, trilling, hissing, growling and grunting as well as cat-specific body language.

Have a couple of these at home, if you are interested, Dave

As an aside I fitted air over hydraulic brakes to my LWB 2a in the 80's, it drew a 2 ton 4 wheel turntable trailer with 3 line full air braking, it worked well, used to be my avatar on here before photofukit fuk it  :smile1
