I just thought they were mating....
LOL Rocket,my first laught of day,,,was funny....
For anyone that never had to stack non stackable freight this pic should give ya good idea whats going on to load it proplely.
I know your walls may not be set up this way but its the same idea.. Also make sure ya strap the top level & make sure your stacking the right weights on those load bars as others said..
The plywood is a real good idea but its 1 more thing ya gotta deal with and move around alot when not in use,(i dont carry it)
Look at bottom of the skid and ya will see how the pallett will sit on the bars..
Most freight in containers can be stacked,, its the palletts that I come across that cant be stacked and use this to load what wont fit on the floor
Each load is diff,,ya just gotta step back and look at things for a sec and figure it out
