I shunted…
On nights at Barnsley glass for Malcolms.
Every trailer (I could load 9 in a shift) would be tied using dolly knots through every second pallet and pulled forwards. The rear would be strapped with pallets.
There is no way the load could possibly survive a roll-over.
The safest way to move these particular loads would be in a exact fit box trailer and loaded 4 at a time from a ramp. But that isn’t cost effective so, they continue to move glass in curtainsiders. It’s a numbers game, subtract the amount of lost loads to the number of successful loads and the bean counters are happy. In my opinion it should all be done in boxes but that’s never gonna happen.
