This awesome multifunctional storage cart is what brought Akro-Mils to my attention in the first place. The ProCart is a great example of intelligent design and flexibility, with simple-to-operate sidewalls that collapse or lock in an upright position, enabling the user to switch from box-top to flat-top; optional rails that allow you to snap bins in and out, as we saw in their ReadySpace system; and while it's made out of polyethylene foam rather than steel, the thing will hold 400 pounds.
This is one of those products where still photos don't do a good job of communicating its utility. Check out the video:
