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:


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.Esquema
  • 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.


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.Esquema
  • Avoid bigger angles than recommended and try to get maximum alignment of the hook when loading.


If hook seat & rigging is not properly fitted, change one of them:
