Another bridge strike

It’s 4m trailer when pulled by a low ride unit which would have a fifth wheel height of around 950mm compared to a Scania which is 1250mm fifth wheel height with mid axle lowered (higher if its lifted, stupidly).

They allow for a larger cubic capacity whilst maintaining the 4m height restriction. You’d normally see them being pulled by units that have removed the top of unit mudguards. Fly by Nite use low ride DAFs as an example.

So that’s 300mm extra height, minimum, on a 4m trailer giving it a height of 4.3m for a bridge at 4.2m. Case closed.
