I am a Theatre Manager at a local preforming arts center for our school board. Today, while removing some weight from a, arbor, weight was miscalculated and our arbor ran away into it's Head Block. Weight has been added back onto the arbor but it feels and looks stuck. The thimbles from the arbor look to be entering the Head Block and one of the metal Fly lines looks to be stuck under a loft block. I'd appreciate any recommendations on how to fix this problem or what type of business to call to make repairs.
