Lighting Truss: Load, Cable Runs, and Maintenance Height

A square lighting truss above the dance floor, composed of 400x400mm aluminum triangular trusses, forming a 10x8 meter frame, suspended by four electric hoists. The entire assembly can be lowered to a height of 1500mm for maintenance. Moving heads, strobe lights, and computer lights are densely clamped onto the truss, each with a safety steel cable. Power and signal cables are bundled and routed along the bottom chord of the truss, secured with Velcro into neat bundles. The truss and all fixtures are matte black. The image shows the truss in a lowered maintenance state, with a technician standing below adjusting the lights. Avoid: truss fixed and not able to be raised or lowered, fixtures without safety steel cables, cables scattered and hanging loose, truss using shiny or colored finishes.

舞池上方一組方形的燈光桁架,由 400x400mm 的鋁製三角桁架組成,四邊圍成一個 10x8 公尺的框,由四組電動吊點懸吊,可以整組降到 1500mm 高進行維修。桁架上密集夾掛著搖頭燈、頻閃燈與電腦燈,每一盞都有安全鋼索。電源線與訊號線沿著桁架的下弦捆紮走線,以魔鬼氈固定成整齊的束。桁架與所有燈具都是消光黑。畫面呈現桁架降下維修的狀態,一位技師站在下方調整燈具。避免:桁架固定不可升降、燈具沒有安全鋼索、線材散落垂下、桁架使用亮面或彩色。
