ABSTRACT:
A lifting apparatus including a base, a load platform, a vertically expandable actuator linkage mechanically coupled between said load platform and said base, and a glycol operated actuator chamber having a compressible bellows. Means are provided for mechanically coupling the compressible bellows between the base or platform and the linkage. This provides an extremely stable platform, and one which remains rock solid once it is set in position, because glycol is a non-compressible fluid and is not affected by normal temperature variations found in industrial settings.
