Lifting Equipment Failure
We recently suffered two events using mechanical lifting eyes.
Both events had very similar immediate, underlying and root causes.
Both involved lifting equipment with lifting eyes
Both raised the load to a significant height
Both had issues with the threaded holes
Both had a dropped object resulting in a significant near hit

Collared eye bolt Dynamo eye bolt
