Sling
A foundry device for handling and conveying flasks and loam-moulds. The stirrup-sling reaches from bottom lugs of a foundation-plate to the binders, or cross for binding the mould together, and serves the purpose of lifting the moulds also. Beam-slings are also stirrup, except that the lower end is usually made to fit the trunnion of a flask; by this means copes are reversed by simply lifting with one sling at each end of the beam. Chain-slings have stirrups, and are joined in pairs generally to one ring. The link-sling is simply a long welded link, and may be round, oval, or square ended. Rope-slings, being flexible, are extremely useful in the foundry. See BEAM-SLINGS; ROPE-SLINGS.
