In the event construction sector, truss bases are core components that underpin structural safety and erection efficiency. Just like the foundation of a building, they carry the full load of the entire display system and maintain its stability.
Developed by WTC, the Cross Truss Base is built around an independent modular design and pin-type quick-assembly structure. It delivers a brand-new, high-efficiency and cost-effective solution for truss system erection, making it an ideal fit for indoor events, pop-up installations, commercial performances and other scenarios.
| Item | Parameter |
|---|---|
| Base Material | No.8 National Standard Channel Steel |
| Channel Steel Section Size | 80×43×5mm |
| Channel Steel Length | 1.5m |
| Weight per Channel Steel | 12.0675kg |
| Structure Type | Cross-shaped, modular combination |
| Compatible Truss Specifications | 290×290mm (F33) 400×400mm (F34) |
2. Uniform Load Distribution via Cross StructureThe cross-shaped configuration enables efficient load transmission in all four directions. It effectively disperses the weight of overhead equipment and lateral stress, reduces single-point pressure, and enhances the overall anti-overturning capacity of the structure.
3. Premium Steel for Exceptional DurabilityThe main body of the base adopts No.8 national standard channel steel. Each piece measures 1.5m in length, 80mm in width, 43mm in height and 5mm in thickness, with a theoretical weight of approximately 8.045kg per meter and 12.07kg per single piece. Boasting high strength and excellent rigidity to withstand heavy loads, the channel steel is finished with rust-proof surface treatment, suitable for long-term indoor and outdoor use.
4. High Compatibility with Multiple Truss SpecificationsEquipped with standard interfaces, the base is compatible with conventional aluminum trusses, connectors, base plates and other accessories. It supports two mainstream aluminum truss specifications: F33 (290×290mm cross-section) and F34 (400×400mm cross-section), allowing seamless integration into existing truss systems without additional modification.
1. Quick Erection: Modular splicing requires no complex tools, significantly reducing construction time and labor costs.
2. Superior Stability: The cross-shaped base enlarges the ground contact area and effectively improves anti-overturning performance.
3. High Load-Bearing Capacity: The channel steel delivers outstanding bending and torsion resistance, providing reliable support for large-scale lighting, audio, LED screens and other heavy equipment.
4. Easy Transportation & Storage: The base can be disassembled into individual channel steels and connectors with minimal space occupation, cutting logistics and storage costs.
5. Aesthetic & Long-Lasting: With refined surface treatment and a sleek, concise appearance, it elevates the overall visual effect of the event venue.
