hell nah, those appear to be way too high
Warehouse engineer here, they aren’t stacked too high but there are major issues.
When you stack pallets of cans or other cylindrical items of a certain height you need to stack with an offset. You do not stack the pallets 4 high that tall directly on top of one another, that’s just creating a highly unstable stack. With this I would have designed two straight stacks then the 3rd and 4th levels on a 2 foot offset.
2nd there is no way I would even allow them to pick or put those pallets with a double stack, and it looks like this cat was going for a triple stack. Hell naw. That is some crazy shyt. Only allow double stack movement if each pallet is 54 inches or less. These stacks are way higher than 55 inches.
Overall this is just an unsafe setup. With the stacks they have and employees not following proper procedures that shyt was bound to happen.
