I'll probably never end up on a serious production with a modern camera crane so I was wondering if anyone who has, could shed some light on some things for me?
1. What technology or process is involved with the moving rear counterweight to counteract the boom moving in and out? Watching videos, I can see that dynamic reaction is instantaneous, how is that set up or calibrated?
2. What moves the boom / telescoping section in and out? Is it some kind of rack or belt drive?
3. Do most crane heads have a built in stabiliser?
Any help is appreciated! I'm struggling to find details youtubes.
