[QUOTE="rlepecha, post: 540964, member: 19679"] This.. Everything is poorly engineered or copied from other designs. A lot of companies makes horseshoe plates, they are all pretty much identical and none seem to fix the apparent weaknesses in the design. Given these parts are all safety critical, as with most industries; welds should be xrayed, NDE done etc. Materials should be checked for conformity to the yeild strengths etc. Final Components should have been suitably designed, including relevant calculations/FEA etc. Proof load testing and fatigue testing done. As far as I am aware, not many companies do this. The parts are just copied designs for something that's been sold for many years. Sounds like the weld on these adjustable plates is not up to spec, it presume it is not a full penetration weld and not checked for flaws, hence the failure which is probably from crack propagation due to fatigue.
