This is a double pulley system that can be used for lifting performers by hand with a 4:1 mechanical advantage.
After rigging a double pulley system properly, you can easily raise and lower aerialists by hand to create dynamic flying acts. With a correct double pulley system you can lift 4 times as much weight with the same amount of work.
This double pulley system includes:
- Rigging Rope: choose from 50ft, 80ft, 100ft, 120ft, 150ft, or 200ft
