<p>An adjustable support stand (30) supports equipment above a foundation. A body (56) has a threaded sleeve (58). A shaft (60) has a support end for supporting the equipment and a threaded end for screwing into the threaded sleeve of the body to adjust a height of the support stand. An isolation bearing assembly (70) is disposed on the support end of the shaft for providing isolation to the equipment. Four legs (46) are connected to the body. Each leg has a vertical channel member (80) in contact with the foundation and a diagonal brace member (90) coupling the vertical channel member to the body. The legs are individually extendable in length. A leg extension assembly (116) can be used to extend the height of the support stand.</p> |
