Maximise Efficiency with Wedge Double Deck Trailers

What is a 'Wedge' Double Deck?

All trailer dimensions and apertures are limited by both the fifth wheel height (typically 1.25m in the UK) and loading bay height.  Historically, to maximise internal cube, a trailer chassis includes a 'step' behind the tractor unit to lower the floor height.  Whilst this does increase internal capacity, the step presents an access challenge and requires some thought about how to load the swan-neck area i.e. the floor space in front of the step.  Various solutions are available such as ramps or internal lifts but these tend to slow down the loading and unloading speed.

The solution: Don-Bur 'Wedge' Double Deck trailers have a straight chassis which eliminates the step entirely.  The neck thickness is minimised to preserve a low floor height at the front and, to maximise internal cube, the rear floor height is lowered as much as possible on small tyres such as R17.5".  To ensure compatibility at the bay, the trailers are typically specified with high lift suspension to raise the rear floor height up to bay level when required.  The result is a trailer that, from the side at least, has the appearance of a wedge.

This solution provides operators with full length, unbroken floor spans on both decks, capable of achieving industry-leading clearances of up to 1928mm (6' 4").

Don-Bur can provide 52 UK pallet capacity on all 'Wedge' Double Deck types, as well as a 60 UK pallet capacity on all LST 'Wedge' Double Decks.
