What is the purpose of the two Ø11 holes on the rib plates on either side of the container saddle?

In the drawings of the standard JBT4712.1 \"Saddle Supports\", there are two Ø11 holes (for M10 bolts) on each of the rib plates on either side of the saddle. Does anyone know what purpose these holes serve?
The holes in the rib plates on both sides of the saddle are bolt holes for grounding
But why don’t supports in the form of ears or legs have holes? Moreover, the ground plate is usually provided separately, and the material should be stainless steel.
This can only be asked of the standard developers...
This is the hole used for static discharge grounding; it is fixed with a bolt, with one end of the copper wire wrapped around the bolt and the other end connected to ground
It’s grounded against static electricity, but still some people ask to add more protection; there’s nothing I can do about it
This is the hole used for static discharge grounding; it is fixed with a bolt, one end of the copper wire is wrapped around the bolt, and the other end is connected to ground. It is mainly because it rusts easily and may become ineffective. It was later changed to a stainless steel ground plate. Punching holes in the reinforcement plates for anti-static grounding was the original intention of those who established the standards for saddles. But it’s not necessarily appropriate.
I also think it’s a hole for static electricity connection
It must be this; I’ve seen it at the scene. :):):)
