I have a client that wants to install some truss over the audience with some LED fixtures to use for house lights, and he wants to have the truss on chain hoists to be able to bring them in for servicing and loading, etc...
As I understood it, chain hoists are really for a temporary type of install -touring shows and such. The idea here is that the motors would be the permanent anchor point for the truss. I have some reservations about going forward with his request as I want it to be done as safely as possible. I know it is a bad idea to do this, but I don't have any kind of documentation to back that up.
Have any of you used electric chain hoists in a permanent installation, and/or can anyone direct me to a specific document allowing or disallowing this type of install?
