How a crate is engineered, briefly
The first job on any crate is finding the real load paths of the thing inside it. On machinery that usually means two or three machined pads that can take the whole weight, with everything else structurally decorative. The crate then holds the object in space rather than holding it up: a heavy skid base carries the mass, cradle blocking contacts only the strong points, and the enclosure carries no product load at all.
The second job is deciding what braces to what. Crate walls flex in transit, so anything braced to a wall receives whatever shock the wall receives. Anything braced back to the skid stays with the mass. Getting that wrong is how a perfectly strong crate delivers a cracked casting.
