CROSBY HOOK HOIST INSPECTION

TAKE THE CROSBY QUIZ

So you think you know how to inspect a hoist hook? Prove it. Danny Bishop, Director of Training at The Crosby Group has put together this quiz to test your hoisting hook inspection know-how. 

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 they aren’t always glaringly obvious like 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 Crosby Group Quiz and find out if you’re a hook inspection pro – or if you have a bit more to learn.

ASME STANDARDS

There are ASME Standards that apply to rigging, and more specifically, hooks for lifting. Although they’re not law themselves, these standards are important to know as they’re directly quoted in Canadian legislation. Be sure to check the manufacturer warnings, usage instructions and other recommendations that may apply to the equipment you’re using.
