Build the Cage with OUR POLE:
With this system (BWOP Build with our pole ) We do not need anything from outside. No chains from roof, no truck crane.
We do use this way for small areas such as tv sets.  Just be sure we can roll the Cage (Photo 1), to the place you want us.
If this one seems too big for your place, we do have a smaller one.
