In the performance industry, the aluminum stage truss or lighting truss comes in sectional lengths connected together to create longer spans or different shapes. And the longer spans or shapes finally constitute different roof truss systems. These roof truss systems are used to support lighting, audio and video equipment, which can be the best solutions for concerts, theaters, exhibitions, trade shows, dj display booth, and indoor & outdoor events, etc. This article is mainly about the introduction of the aluminum roof truss system in details, hoping customers can have better reference for the truss structures.
The complete aluminum truss roof systems can be divided into 3 parts: pillar, beam and ceiling.
● Pillar
There are two types for the Pillars: Lifting system and Non-lifting system.
a) Lifting System
The main accessories required for a pillar include: basement (including 4 outriggers), one 1M straight truss section, 4 hinges, straight truss sections, 1 sleeve block, and 1 top section.
There is no hinges on the bolt tube truss, only the reverse head. The length of the reverse head is generally 1M, 1.2M and 1.5M according to the size of the beam. The lighting truss beams of 300*300, 400*400, 450*450 use 1M reverse head, the lighting truss beams of 400*600, 500*600 use 1.2M reverse head, and the lighting truss beams of 520*760, 600*760 use 1.5M reverse head.
