I've seen a few machines this size in action and they are pretty awesome and amazing to see!!! These machines generally tend to be soft mount, their shock absorber look EXACTLY like those on semi trailers and many of these machines actually stand themselves up. They wash sitting down, not utilizing their shocks, but then they stand up and sit on their shocks to spin, they rise about 6 inches to a foot, it's pretty neat to watch! Here is a picture of a washer shock absorber by the Washex company:
