Rope in them. The top block is fastened to a jib crane and from it rod and breast-piece extend. This breast-piece and rod are for off - setting the strain exerted in pulling on the rope. The helper places the breast piece across his breast and then pulls on the rope. The caster steadies the tongs with his hands. The rod, attached to the breast piece, also serves to push the crane around to the molds. The rope does not burn as it is too far from the fire and a long hook is used to connect the crucible tongs and the lower tackle block. The advantage of the arrangement is that it provides a much more rapid means of pulling out the crucible than with a chain block, and it also is used for holding and steadying the crucible while it is being poured into the molds.
