I’m working on building crates that will hold 3 and 6 tons. My idea is to use 3/4 plywood with 4×4s between like a sammich. Full size 4×8 bottom with ends capping sides. Gonna put 2×4s on top of side pieces to prevent trash falling between. Need to make sure they’ll hold the weight though. Any help is greatly appreciated.

Use white oak. It has a shearing capacity of 10,000 pounds per inch.

Excuse my ignorance on this topic, but how exactly does all that work? It needs to be able to be lifted by crane regularly too, forgot to mention that.

I’d like to suggest having an engineer design the crate. 6 tons is a huge amount of weight that should be properly held at any height.

Not knowing what you are using this for, I think that steel will probably be a better material than wood as well.

Welded steel, skinned in plywood.

I also believe there are codes of federal regulations that give specifications for such crates and they have to meet the minimum standards.

I would go to a machine shop, tell them the dimensions and capacity and have them build it.

Wouldn’t it be cheaper and easier to just use short shipping containers? They are already designed to be lifted by cranes and are available used fairly cheap compared to what you are about to build. I’ve seen them in good shape selling for $1-2,000. Bolt your cargo in the center of one and ship it.

Judging by the rather sketchy information you have given, I’m guessing you are looking for a 3 and 6 ton open container that will hold scrap or demolition material. If that is the case, wood is not the best material to use as it would get beat up pretty quickly. Better to use steel and welded construction. You could also buy containers from Dumpster.

It’s not for shipping. More like construction cleanup. I need something I can tip easily, can take a beating or be fixed easy, and that I can build or buy cheap. Building a wooden crate is easy. I just need to know what to do to ensure it’ll hold up to 5 or 6 tons and can be moved around again and again.

If you try to build something out of wood to hold 5 or 6 tons, the box would probably outweigh the scrap. And I doubt it would last very long being handled by a crane over and over. You’d end up building it over and over again, and soon the price would be what it would have cost to do it in metal the first time.
You really should see if there’s a welding shop anywhere near you and get some quotes.

Thank you to everyone who had constructive input. I appreciate it. To the smart ass, your comment is neither wanted or required. If you have an actual recommendation, I’m open. Otherwise, keep it to yourself. Thanks.
