CHOOSE PROPERLY
Think about how the hook and the rigging as a whole team:
What kind of RIGGING (“below the hook” devices) is used? Is it accommodated properly to the hook? Two aspects to consider:
- Material grade: try to use similar hardness grades: do not mix carbon steel with very allow ones.
- Dimensions: try to have as much contact as possible in between.
Have a look to all variety of IRIZAR hooks and, if possible, request the right sections in the saddle to get the best bending radius:
HAVE CONTROL OVER IT
Take advantage of the hook you have and optimize all lifting line.
- Check if the contact between the rigging (slings/ropes/masterlinks/chain) and the hook seat is the proper one. Both should adapt to the saddle radius to have as much contact as possible.
- Even if the wear is permissible, do measure it. Do NOT permit any wear > 5% of nominal dimension.
- Frequent visual inspection will help. Check specially those areas where the load is transmitted through, as the hook seats are.
REACT!
Do not let it be too late: its always cheaper to replace before any accident:
- Ask to original manufacturer as IRIZAR is, about proper instruction for any corrective action.
- WELDING is never an option: strictly prohibited by all international rules & standards.
- Use appropriate combination for each case. Remember the contact between both, hook & rigging, will determine the operation safety.
- Avoid bigger angles than recommended and try to get maximum alignment of the hook when loading.
ACTION
If hook seat & rigging is not properly fitted, change one of them:
- New Hook: ask to IRIZAR FORGE: irizar@irizarforge.com
- New Rigging: ask to VAN BEEST: sales@vanbeest.nl
