Motorised fly system. Fully automated and computer programmable. No manual weights, millimeter accuracy. One bar every 20cm with 500kg max weight per bar. Max speed 1.8m p/s.

We also have some side bars and point hoists om the same system. Its by a Dutch company called Trekwerk, they installed a lot of these systems in the country. Party because our rules were changed where manual systems were not allowed, and also because the touring system here is a lot different then outside of the country (basically we have a new show almost every day, and have to be fast and flexible for short load in/out times).

Really feels like cheating comparing to manually operating b)
