This is the type used for concrete panels.
Empty spillage in there. 3 rams each side to push against load.

That is what is know as a float liner, it carries lots of sheets of float ( float glass )
For hundreds of years now glass as been floated on a bed of molten tin while melting the glass as glass will always float and lie perfectly flat and straight on a bed of molten tin.
Before then glass had what was known as bullseyes, glass was attached to poles, blown and spun leaving a big circular bulge in the centre of the glass ( the bullseye ).

Next time we get a delivery and I’m in the yard, I’ll take some photos. Or I’ll ask someone else to do it for me. Our glass comes from Saint-Gobain as for many firms. Stock levels are currently dwindling…
There’s no shortage of sand is there?

Glass is amazing, you can smash it to smithereens and turn it back to glass. you can grind it up and use it on beaches, or you can put it in pool filters.
Used to pull these trailers when I worked for LIFT (Luxguard International Floatglass Transportation) which is a part of Offergeld.
There is a metal frame/stillage holding sheets of glass which when the trailer is lowered it then reverses over frame, trailer is then raised picking up the frame, then hydraulic clamps within the trailer are used to hold the sheets of glass in place for transporting.
One of the easiest jobs I ever had, just picked loaded frame up at factory then on to delivery point either in UK or Ireland/Europe & drop frame, pull out & wait for them to tip it, reverse back in & pick up empty frame & away you go. Doddle of a job

Juddian:
Glass carrier.How its been explained to me by someone who used to drive one.
Body attached to outer rolling shell, load sits on stillage which itself form the main chassis and locks the whole lot together, axles are stub only, driver drops it down to the ground unlocks the body from the stillage/frame and pulls the body on its wheels straight forward, after (un)loading backs onto and picks up stillage/frame and drives away.
You can’t drive the body on its wheels about without the frame present, straight forward/backward movements only.Lots of air involved and the vehicle never really shuts down, pads are in place to keep the glass sheets compressed together and that pressure must be constant.
Quite a piece of kit then, and sounds expensive too
I have pulled the open ones used for a skid with pre cast concrete panals. Had to have trailer insurance for £90000.00

My “shortage” comment was a bit tongue in cheek, the Sahara is fairly vast…
