ABSTRACT:
Load-bearing devices, each including an overload indicator of the present invention interconnecting load bearing connectors, preferably elongated load bearing connectors are provided. 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 modified wire form link, preferably either a modified welded link or a modified quick link, generally having a first thickness and first and second elongated sides. The modified link preferably includes two elongated sides, one of which preferably has a portion having a diminished thickness narrower than the first thickness. The diminished thickness preferably has a generally predetermined load bearing capacity or capability and is calibrated to reduce the load bearing capacity or capability of the overload indicator. Methods of making an overload indicator and a load bearing device including an overload indicators of the present invention are also disclosed.
