In a warehouse stack height is often set by what fits; in a vehicle the stack carries much larger forces. EU Directive 2014/47/EU (Annex III) requires load securing to withstand 0.8 times the cargo weight forward and 0.5 times sideways and backward, and to prevent tilting or tipping.
Take the permitted number of tiers from the stacking instruction of the container model; ask Aris Makina for it, since we obtain it from GEBHARDT and pass it on. Then try it with the real load and packaging in a controlled area:
- Do the bases sit fully on the container below?
- Does the stack slide?
- Is there crushing in the bottom container or the product itself?
- Does the securing point hold?
Crushed product or a warped carton is the first sign that the stack limit was exceeded, and without records it often shows up as waste. Run the trial at the temperature the container will work at; in a vehicle trial, lashing and braking are carried out only by an authorised crew.
Make the limit visible: a line drawn on the rack or the vehicle wall answers how many containers go on faster than a written rule. Renew the approval when the container, packaging, floor or transport method changes.
