Hi janeislay
The headstock is split vertically and each side pivots on a large bolt & it fastens at the top with a hook & eye, the goat can raise or lower its head and is only restricted from side to side. It is not light weight and I have mine in a permanent position although it could be made lighter and fold-able, I was going to take more photos today but it never stopped raining, I will make sure I get some tomorrow this one is from my phone if it works
