- Demonstrated a new lightweight deck which allows for increased payload for weight limited operation.
- Identified which operations could benefit from lightweighting.
- Double deck trailers in grocery haulage and ‘walking-floor’ trailers in bulk haulage are two operations that can benefit significantly from lightweighting.
- A weight saving of 1,000 – 2,000 kg can be achieved on a 13.6 m single deck box trailer through a combination of lightweighting measures:
|Component||Weight Saving (kg)|
|Optimised chassis beams||200 – 900|
|Lightweight sandwich sidewalls||300 – 500|
|Lightweight sandwich deck||100 – 200|
|Glass fibre running gear||250|
|Carbon fibre wheels||150|
|TOTAL||1,000 – 2,000|
% fuel saving
A weight saving of 1,000 – 2,000 kg would allow an additional 3 – 6 roll cages to be carried.
Each additional roll cage corresponds to a 1.5% improvement in fuel consumption for a 13.6 m single deck trailer.
% CO2e Saving
% Carbon saving is equal to the fuel saving.
Cost of implementation
Raw material cost of a lightweight deck is approx. two times greater than for standard hardwood deck.
- Applying lightweight composite materials to trailer subcomponents such as decking and side walls can be implemented in short time frames for a minimal increase in cost.
- For a long-term solution, more radical changes will be needed to drastically reduce empty trailer weight.
- Holistic lightweight composite trailers will become increasingly viable as greater emphasis is placed on energy consumption of the road freight industry.
