Abstract:
A handling device for lifting a crucible with a diameter that releasably attaches the crucible to lifting device for lifting and lowering comprising:a. a frame that has leg pieces each with a center end and an outward end and whose length is slightly larger than the radius of the crucible and the leg pieces are attached together at a point at the center end and, the frame has vertical pieces, each with a top and bottom end and each of the vertical pieces' top end attaches to the outward end of the leg piece such that when the frame is centered over the crucible the frame is slightly larger than the crucible's diameter and hinged pieces attached to the bottom end of each of the vertical pieces and each hinged piece has a bottom ringing retainer and the frames heights is approximately the crucible's height; and, b. rigging adapted to pass through the bottom rigging retainer; and c. a top rigging retainer means that is adapted to allow the rigging to pass through it attached to the top of the frame; and, d. a means for attaching rigging to the lifting device; and, e. a means for attaching the frame to the lifting device; and f. whereas the lifting device is attached to the frame and the frame is then positioned over the crucible and said frame is lowered by the lifting device and positioned over the crucible and lowered and said means for attaching the frame to the lifting device is detached and said rigging is attached to the lifting device, and the lifting device begins to lift enabling the frame and the rigging to securely grab the crucible and as said lifting device continues the crucible is lifted.
