Rigging
Rigging involves hanging loads. This includes both trusses and loudspeaker systems or lighting technology a>. Rigging must ensure the safety of the workers erecting the truss structure as well as that of visitors staying near these structures.
For the former, you will find PPE, chain hoists and various other accessories. As far as the latter is concerned, a variety of couplers, shackles, safety devices, etc. are available. In particular, moving heads or spotlights are securely attached to the trusses so that there is no danger to your audience or your artists.
