I had a customer who wanted to do an immediate loose cargo test, but did not have a machine. The lead time to purchase this machine from a company that makes them is 6 to 8 weeks. I was able to design, fabricate, and test this machine within their two week deadline. The basis of this machine is that it moves in a circle at 300 rpm, which sends a package jumping and bouncing around in the test area. This test is very rough and I have seen it turn products to dust in a box.
