I was wondering if anyone has any information on this truck.
Is the rear set of wheels (don’t know what you call that!) operating independently/remotely from the front. To get a better turning circle?
I should imagine that the rear load platform
rotates, and it looks like front axle of trailer turns
Ah OK, I see. Thanks
more commonly known as a bolster and bogey set, they were used commonly here for long pipes or beams before triple extenders came in. the load sits on a turntable on top of the bogey as the unit turns the load will turn the turn the turntable , and that action by hydraulics or rods will turn the axles on the bogey
OK… what’s an extender? Can you link me to a photo online? Is it this?

Yes that’s an extender, as the name suggests the trailer is able to extend in length, you can get most non rear steered extenders that go up to around 60 foot-
aka trombone trailers
It is also a little known fact that it is perfectly legal to use very long trailers… as long as at least one leg of a trip has a long load
and the trailer has a C&U certificate this was a 50 foot long rigid trailer, once tipped of the long load it loaded bricks back home that only filled 3/4 of the trailer- I have images of 70, 80 and 100 foot rigid trailers if anyones interested

this mx-cargo.pl/en/photos/ might help
So what is illegal? I thought there were restrictions on the length - what does that apply to?

The law applies to all trailers, but there is an exemption in law for trailers designed to carry loads of exceptional length. As long as one part of any journey the trailer has a load on that needs the long trailer it is totally legal… for example that load above, I loaded 50 foot steel beams from Teesside to Norfolk, that makes it all legal, I then loaded 40 foot long piling drills in Great Yarmouth for West Bromwich where they were going for repair, once empty in West Bromwich I loaded just around the corner 20 foot long flat bars for Lion Weld in Middlesborough and home. As long as at least one leg on a trip to and from base requires the use of a long trailer its all legal.
Similarly another anomaly in law, A 100 foot long load (back then) required a second man in the cab, and to be notified to the police/highways etc, but it was perfectly legal to take the same 100 foot long trailer out on the road without a 2nd man or notifying if it was empty- the law says LOADS must be notified/have a 2nd man not the vehicle/Trailer itself. We used to regularly run down to Wards of Sherburn empty with 70 and 80 foot trailers with no 2nd man and no notification and our 2nd man would meet us with a movement order once loaded
I suppose the route is sort of straight then with that length of load?!

Not really use the same routes as everyone else, just with a tad more thought

aka trombone trailers
A ■■■■■■■■■■■■■■ is the most enjoyable sort - google will explain for anyone interested in this particular type of trombone.
