I am working on transferring a dead hung electric to a new double purchase lineset. Without getting too far into the engineering, the system has a total of 26 linesets with the t-track for more. The electric is awkwardly trussed: top and bottom batten either side of the raceway and an 18" bracket out to a third overhang batten. The overhang pipe is to be struck once we can safely get to it.
The question is... What is the best procedure for transferring to the new rigging?
So far we have discussed attaching the batten and overhauling it with a chain motor. With it being double purchase the op rail is sitting on a deck above the stage. We would attach our chain motor to a pallet of weight on the deck ~2100 lbs and run the hook up to the arbor through the op deck grid. Once the arbor is in we could load weight and lower it to working height, remove some weight and pull the overhang off.
BUT, we may not have access to a chain motor. The thought then is to use a chain fall or lever hoist in its place.
Trying to think outside the box AND, more importantly, keep my crew safe!
