Powered Flying, Pushbutton Simplicity
Powered flying is the luxury pushbutton alternative to manually operated raise and lower gear for flying scenery, lighting rigs, reefer curtains, bridges and even to assist safety curtains. The principals are very similar to manual systems, except that electric hoists replace weight cradles, winches and manual effort.
And don't think that powered flying is limited to professional theatres with limitless budgets - similar systems are often provided in schools where daily access, insurance, teaching and disability regulations are regular considerations. Leisure centres can also find a second income when able to lower their performance facilities for an evening show!
Most installations use individually designed pile-winding or helical-grooved drums, which ensure that multiple cables travel equally to ensure that flying equipment remains level. Chain hoists are a simpler option and ideal for single lines, portable use, or to spread the load for heavier applications.
