Truss accessories are key supports for ensuring the stable assembly, functional expansion, and safe use of trusses. Rigging Hardware They are categorized into four core types: "connection & fixation, functional expansion, safety protection, and auxiliary tools". The selection and use of these accessories must adhere to the three core principles of "material matching,Truss Accessories load-bearing adaptation, and scenario adaptation". A detailed summary is as follows: I. Core Functions and Key Requirements of the Four Accessory Types
1. Core Connection Accessories: The "Skeletal Joints" of Trusses
Including flange connectors, latch-type connectors, right-angle/angle connectors, and high-strength bolts & nuts. Their core function is to accomplish the splicing of truss units and, at the same time, Stage Accessories guarantee the structural stability. Key Requirements:
Materials must match the main truss (aluminum trusses with aluminum alloy flanges, steel trusses with carbon steel flanges);
Bolt torque and latch anti-loosening buckles must meet standards to avoid connection failure.
2. Functional Expansion Accessories: The "Capability Extenders" of Trusses
Including equipment hangers, cable management channels, sunshade/rain shelter connectors, and adjustable bases. Their core function is to upgrade trusses from "pure load-bearing structures" to "multi-functional carriers", adapting to needs such as lighting suspension, cable organization, and outdoor protection.
Key Requirements:
The load capacity of hangers shall not exceed 80% of the truss’s rated load;
Adjustable bases must be calibrated to be level;
3. Safety Protection Accessories: The "Risk Mitigation Shield" of Trusses
Including safety guardrail interfaces, wind-resistant cables & ground anchors, anti-slip pads, and warning signs. Stage Hardware Accessories Their main job is to make sure people are safe and help the truss stand up better to outdoor risks. Key Requirements:
The lateral pull force of guardrail interfaces shall be ≥500N;
The burial depth of wind-resistant cable ground anchors shall be ≥0.8m;
Anti-slip pads shall fully cover contact surfaces;
Truss Accessories Warning signs shall be clear and prominently placed.
4. Auxiliary Tool Accessories: The "Efficiency Aids" for Truss Installation
Including torque wrenches, levels, positioning pins, Truss Accessories For Stage Lighting and storage boxes. Their core function is to improve the accuracy and efficiency of installation and prevent accessory loss.
Key Requirements:
Torque wrenches must be calibrated to 30-40N・m;
The accuracy of levels shall be ±0.5mm/m;
The diameter of positioning pins must match the bolt holes.
II. Core Principles for Accessory Selection and Use
1. Material Matching
For aluminum trusses: Prioritize Aluminum Truss Mounting Hardware alloy/stainless steel accessories (to prevent electrochemical corrosion); For steel trusses: Select carbon steel/hot-dip galvanized accessories (to ensure strength);
Avoid material mixing to prevent wear and tear.
2. Load-Bearing Adaptation
The rated load capacity of accessories shall not be less than 80% of the main truss;
For heavy-load scenarios (e.g., suspending LED screens), select "heavy-duty" accessories (such as Grade 10.9 bolts and load-bearing frame hangers).
3. Scenario Adaptation
For outdoor use: Choose corrosion-resistant and wind-resistant accessories;
For frequent assembly/disassembly: Truss Component Parts Select quick-connect accessories (e.g., latch-type connectors);
For temporary stands: Guardrails and anti-slip pads are mandatory.
