1. Truss


A stage truss is a piece of stage equipment that is designed to support lighting, screens, and other accessories. Stage trusses may be permanently installed, as in a theater with a trusswork system suspended from the ceiling, or they may be movable. Stage trusses are used in a variety of settings, from public parks used for concert series to opera houses, and they are constructed by a number of different companies, several of which are capable of fabricating custom trusses for specific applications. Classically, a stage truss takes the form of a box truss, which may be welded or bolted to other trusses to create a stand, or maybe designed to be suspended from rigging in a building used for performances. The structural elements of the stage truss can be used as attachment points for lighting instruments, pulleys for moving performers or scenery, special effects devices like bubble makers, and monitors or screens. Stage trusses also commonly provide support for the extensive wiring and cabling used in performance, from wiring associated with individual lights on a stage truss to a microphone cord. Also known as lighting racks, stage trusses are sometimes visible in the performance. People who attend outdoor concerts may have noted stage trusses over the stage and along the side of the stage, and the design of indoor venues may also allow patrons to see the trusses. These devices are usually installed with redundant safety precautions to reduce the risk of an accident caused by a falling or improperly secured truss. Since stage trusses may need to bear a great deal of weight, safety is important at the time of installation. Portable truss systems are often available for rental. A portable stage truss can be used for tasks such as setting up racks of lighting at an outdoor party, supporting a tent for a backyard wedding, or providing structural support for a booth at a trade show. Companies which specialize in events often keep a number of portable trusses in their stock and they take care of installation on site. The truss will usually have a load rating which should be carefully noted.

2. Rigging


Rigging is the process of setting up different types of event equipment on a variety of event structures (trusses) either manually, by cranes, or hoists. Technicians use a variety of rigging equipment – cables, chains, ropes, clamps, straps, etc. – to attach equipment to the truss. These trusses bear the weight of massive speaker units, dozens of moving lights, hanging LED screens, staging sets, and any else that is in the air during your event. In order to ensure that everything goes well, load calculations and safety checks are carried out prior to the setup of any structure. Strict engineering rules are applied by all members of AV Alliance to provide safe structures and solutions for all different event types and sizes.
