In order to install speakers or lighting systems on stage, truss systems are used. The crossbars commonly consist of aluminium but when there are especially heavy pieces of equipment, truss systems made of steel are put to use. Truss systems are fixated with special clamps.
There are three different means of construction: The first way to set up a truss system is by using stands. This method is mostly used for smaller stages and events. A truss is mounted onto stands that can carry lighting systems or other equipment. There are simple systems that can be cranked up by hand and more advanced engine-driven systems. The second option is to hang the crossbars from the ceiling of the stage. They can be lowered to attach or detach equipment. This kind of system often comes to practice in larger venues or theatres and is convenient because there are no stands necessary on or beside the stage. The third alternative is rigging with ground support, where the crossbars are mounted to towers that are built on or beside the stage. They can be lifted up with motorized cranes and there can be additional crossbars attached during a show. Ground support offers the sturdiest support and it can be deployed regardless of the positioning of the stage. Furthermore it can be equipped with a roof and therefore serve as a fully functional open air stage.
For rigging a stage, a variety of different equipment and a fair share of know how is needed. Lighting equipment has to be secured with safety ropes, the determinations of weight have to be complied with and extra stage platforms or trusses have to be positioned effectively. Stage construction is challenging and we offer you the best equipment possible for a professionally built stage and a spectacular show.
