I was recently watching a you tube channel, they were rescuing a trailer that had sunk. Apparently they left it on the side of the road and when it rained the ground gave way.
Anyway I noticed the the airlines were connected to the trailer and not the unit, they were higher also straight not coiled like in the UK, was wondering how it works when the truck goes around corners and is it better to have lines on the trailer

They seem stuck in the previous century over there, they still have palm couplings ffs!

No iit was a box trailer, I will link the video if I find it.

The reason I asked, I was wondering whether it was actually hydraulic hoses, not air-lines?
I have seen pictures of both coiled plastic, and uncoiled “rubber” air lines on US trucks, but they were fixed to tractor, and not trailer.
When I`ve seen the uncoiled type they were supported on a spring loaded pole.
US rules seem to allow for much longer tractors, with a less tight turning circle, and a greater distance between unit and trailer.
Uncoiled type lines might work there, but I doubt they would work well with our close coupled trucks with tight turning circles.
But I`ve never worked US so open to correction.
Some have coiled air lines, some straight. They don’t connect with suzies like Europe they are 2 90 degree glad hands and an electric connector on a regular 53 foot trailer. I find coiled lines are more awkward and tend to catch on themselves and prefer the two airlines and electric line grouped together in a sleeve for ease of use. They are not close coupled here as they are in Europe, and most things are different. Some of that is a reluctance to change, and some of it actually does make sense. It is much easier to repair a hub brake or change a tire with manual tools at the side of the road than a disc or wide single tire for instance , but the superior performance of disc’s is slowly growing and most trailers have them now. Amt gearboxes too are getting much more common but most experienced drivers hate them just because they’re not the awful manual Eaton they’ve been taught to worship.
There’s no dog clip or secondary device on the 5th wheel and the trailer air supply shut off is on the vehicle dash not on the trailer.
There is an overall length maximum of i think 75 feet, and a max trailer length of 53 feet. Trailers over 2 axles need permits and aren’t common. Max length between kingpin and centre of axle set ( bridge law) is 41 feet ( California is different) and max weight on drives and trailer set is 34000 lbs, so it’s usual to weigh, and slide the trailer to a point where the weights and bridge is legal.
To drop a trailer it’s just a case of wind down the legs, undo the gladhands and electric connector and pull the 5th wheel release handle, to hook up reconnect air and wind up. There is often more space to manouver here and roads are built to be truck friendly, there is a minimum height clearance on all roads and towns of 13.6" unless posted ( and it’s not common to see those restrictions) so every thing is 13.6" tall ( higher needs permit). The traditional long nose trucks as well as being cramped weapons of torture are more awkward to bend into spots due to their wheelbase but most aerodynamic trucks are pretty good on steering and easy to move around, although there are plenty of older places in town that were built for the old 48 foot trailers that can be a proper headache to a driver. Montreal and old cities in Florida are well equipped with these nightmare spots.
The whole job is completely different to Europe, not better or worse just really different. From the hours worked to distance covered to pay and conditions it’s totally different.

Maybe it was a walking floor trailer you saw like this one, hydraulic lines are left on it when dropped.
