Rigging concerns itself with securing heavy loads. This includes truss as well as speaker systems and lighting technology. But as always, safety comes first. The rigging ensures both the safety of your workers during the construction process, as well as the safety of your visitors who will be in close proximity to the truss systems.
For the former you will find all kinds of PSA, chain hoists as well as other additional equipments. Couplers, shackles, safeties, etc. are available for the latter. They are mainly used to fasten moving heads or spotlights to the truss and provide a maximum amount of safety for your artists and audience.
