Measure the opening width 'e' of the load hook.

   Measure the base height 'f' of the load hook.

   The measured values should neither exceed nor fall short of the values in the table.

   If the load hook has been widened to a greater degree than is allowed or if the base height is below the permissible limit, replace the load hook.

   If the load hook is deformed (even if within the measurements given above): Inspect the surface for cracks.
