CROSBY HOOK HOIST INSPECTION
TAKE THE CROSBY QUIZ
So you think you know how to inspect a hoist hook? Prove it. Take the Crosby Quiz and find out if you’re a pro at inspecting hooks for hoisting, or if you should get some more training.
It’s important to know what makes a hook no longer safe to use – there are a number of factors that contribute to this, and aren’t always glaringly obvious like it being broken or crooked.
Hooks that don’t pass inspection can cause the load to release, and this can result in damaged materials, injured workers or legal consequences. It’s important to conduct inspections before you use the sling – each time.
Take the Quiz from Crosby and find out if you’re a hook inspection pro, or if you have a bit more to learn.
