The invention is a device that is used to securely hold a crucible for lifting by a lifting device. It has a circular frame with a top bracing leg that ensures straight vertical lifting and proper alignment of the rigging. The frame diameter is slightly larger than the crucible. Vertical pieces extend downward from the top of the frame. At the bottom end of each of these vertical pieces, a hinged piece is attached. On the hinged pieces, a bottom rigging retainer is attached. The bottom rigging retainer allows the rigging to freely pass through it. The bottom rigging retainer with the hinged piece forms a loop through which the rigging is thread. The rigging securely holds the bottom of the crucible. A lifting device is attached to the riggings to lift the crucible. The frame can be made adjustable to fit many sizes of crucibles.
