A system includes a vessel configured to contain a substance therein having a top end and a bottom end with a center-of-gravity for the vessel disposed between the top end and the bottom end, a frame connected to the vessel, a cable link connected to the frame configured to connect a cable thereto, and a cable support connected to the vessel or the frame. The cable support disposed above the center-of-gravity of the vessel with respect to the top end and the bottom end of the vessel. As the vessel moves from a first position to a second position, the cable engages the cable support such that a lifting force is translated from the cable and through the cable support to have the cable move the vessel through the cable support, the cable support attached to the frame or the vessel with the cable support disposed above the center-of-gravity. |
