www.entertainmentengineeringmagazine.com: Frames for truss systems designed to support stadium lighting, sound equipment, and even bleacher seating systems are often composed of extruded aluminum tubing and solid or tubular couplers. Considerable liability surrounds the use of these systems for public events, and the interface between these components becomes crucial to the integrity of the system.

Hammering in the aluminum pins even with a soft mallet is a bit nerve wracking when you could deform the truss or pin with a wrong hit. In a high stress environment where you are trying to put up a traveling show or set, being able to rely on your truss being reliably stable and in the air is a nonnegotiable. With timeframes being close to 24 to 48 hours to put in your set and if you’re lucky the same amount of time to break it down you need to be able to rely on your equipment and not worry about a stray hammer blow. I can not tell if you need the specialized chucks to install the coiled spring so it will fit. If you do that is more annoying than being able to carry a soft blow but if it leads to less deformation in the truss and it lasts longer than having a chuck to put into a hand held drill does not seem like the worst thing in the world, just inconvenient.
Despite potential differences in workflow that arise from particular changes in the installation of a new part, it is great to hear about needed interventions for large truss systems that increase the safety and reliability of these systems while also mitigating the chance of harm or damage to the systems. Especially in such large or permanent installations where important pieces may be overlooked in the short time frames in which these systems are used. What is more interesting is if these coiled pins cost more to produce and how the manufacturing changes as a result of this desire to move away from the steel pins and instead move to the coiled stainless steel pins. Would truss people move to different manufacturers to make these new pins? Or stay with prior manufacturers that then have to change their processes for this new part? Is so, how much do the truss manufactures upcharge (if at all) for needing to change their operation and tooling to make this happen?
