Yes, we do same for other parts of stage which moves up and down only as you describe. I should make clear this particular stage is rotating and fully circular.

Also reviewed a performance stage where the platform could be lowered into a pit, but it didn't rotate. They installed sidewall sprinklers at the lower level around the entire platform to protect it in the lower position while the sprinklers at the roof protected it in the raised position. rick matsuda city of dallas -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Geir Jensen Sent: Friday, September 17, 2010 6:57 AM To: [email protected] Subject: Moving part of sprinkler system A part of a theater stage is moving up-down and may turn up to 360 degrees. Building is fully sprinklered except for the moving part which contain LH type of combustible material and require 6-10 sprinkler heads. Does a design exist to accommodate this? A swivel pipe connection or a 360 degree twistable coil of flexible pipe or hose is my immediate idea. However, suspect neither listed nor offered designs are available for such application? We considered stand alone system for the moving part, but challenges are cost, maintentence, space, certifications etc. Appreciate any advice...
