generally, in our aluminum lighting truss installation works, there are ways of rigging lighting truss.
the first way, it is rigging lighting truss verticlly from ground to high place in the air.
it shall use hoists to rig trusses up by pillars with help of other hoisting mechanism parts, such as top section, hoist set, outriggers, firber sling.
shown as the pictures.
(1) two pillars to rig a lighting truss beam.
a obvious example is the gentry truss system( goal post truss) for led system. it uses to pillars to take all load and rig the truss beam up with hoists.
(2) 4 pillars to rig one toproof lighting truss system
the most prominent example is the nonroof truss system. 4 sides lighting truss beams are rigged by 4 pillars at 4 corners with hoists.
(3) 6pillars or more pillars to rig a large truss system with led sound system.
the second way, it is rigging lighting truss one end from ground to the air and the other end supported on the ground.
in this way, we usually shall use winch system to rig up the lighting truss. with assitance of hinge truss and tower crane system.
(1) rigging truss up as a stage truss system pillar support. it widely known as all truss system with pillars.
(2)rigging aluminum truss up as main stem to hold speakers, the most well known example is PA truss tower.
The Steel Black Truss Base Plate for Aluminum Spigot Truss is an essential component in the construction and stability of truss systems. Made from high-quality steel, this base plate provides a strong and durable foundation for the truss structure.
