ABSTRACT:
Apparatus (10) for engaging, raising and rotating tanks/cylinders (48) which store or otherwise contain liquids or gases under pressure. The apparatus consists, basically, in a cradle (30) which is rotationally mounted on a single elevator housing (22). When the tank/cylinder is elevated, the cradle is either simultaneously or subsequently rotated in a plane orthogonal to the front-back axis of the apparatus base assembly (12). Torque and stresses placed on this apparatus are minimized and, in the interest of safety, the tanks/cylinders are rotated and maintained close (in) to the main vertical support at an elevation above the firmament which is the optimum consistent with the operation being performed safely.
