27,481 lbs CHEP TEST 2005

Yes, the edge rack support (creep) test showed the load at failure was 27,481 lbs using a vintex air bag to distribute the load over the full pallet area supported on “I” beams each side.  I remember one person in authority saying the air bag burst.

That is near enough 12.5 tonne, much more than sufficient and with a large safety factor.

The steel material was less than 1mm thick.

BUT IT DOES NOT NEED TO BE THAT STRONG.   MOST LOADS ARE UNDER 800KG.
