Abstract
A load-bearing device including an overload indicator and a wire form overload indicator are provided for interconnection of load bearing connectors, preferably elongated load bearing connectors, for bearing a load. In preferred embodiments, the load bearing connectors are chains, ropes, wire ropes, cables, straps and the like, preferably chain. The wire form overload indicator preferably includes a wire form quick-link having a first thickness, and first and second elongated sides. The first elongated side preferably includes an interconnectable gap through which connection loops of the load bearing connectors can pass when the interconnectable gap is unconnected. The interconnectable gap includes a connection end and a connectable end, the connecting end having a connector capable of connecting the connecting end to the connectable end to close the gap. The second elongated side preferably has a portion having a diminished thickness as compared to the first thickness. The diminished thickness preferably has a predetermined load bearing capability and is calibrated to reduce the load bearing capability of the methods of making an overload indicator and a load bearing device including an overload indicator are also provided.
