Overview
Mobile trusses are modular structural systems widely used in event production, theater, and exhibition industries. Unlike permanent trusses, they feature quick-connect mechanisms and lightweight materials for rapid deployment. These systems evolved from traditional scaffolding, with modern versions prioritizing weight reduction without compromising strength. The modular design allows customization for diverse spatial requirements, making them indispensable for temporary installations.
Structure and Working Principle
A typical mobile truss consists of triangular or square aluminum alloy segments with standardized connection points. The geometric design distributes loads efficiently across the structure through axial forces in its members. Weight-bearing capacity depends on the material thickness and joint design. High-grade aluminum alloys (6061-T6 or 6082-T6) offer optimal strength-to-weight ratios, while steel variants provide higher load capacities for heavy equipment.
Key Features
Portability defines mobile trusses, with most systems designed for tool-free assembly using locking pins or clamp systems. Many incorporate wheel mounts for rolling configurations. Corrosion-resistant coatings extend service life for outdoor use. Advanced variants feature integrated cable management and accessory mounts for lighting/AV equipment. Load ratings typically range from 300kg to 2000kg per section depending on specifications.
Application Areas
Event production accounts for 60% of mobile truss usage, particularly for concert stages and exhibition booths. Theatrical productions utilize them for flying systems and set support. Trade show builders value their reconfigurability between events. Emerging applications include temporary architectural installations and disaster relief structures where rapid deployment is critical.
Maintenance and Precautions
Regular inspection for structural integrity is mandatory - check for cracks at weld points and deformation of load-bearing members. Lubricate moving parts annually with dry silicone spray. Always follow manufacturer's load diagrams and never exceed rated capacities. Use safety cables for overhead installations. Store disassembled in dry conditions to prevent galvanic corrosion between dissimilar metals.
B2B Procurement Guide
For event production companies, prioritize suppliers offering complete systems including bases, connectors and transport cases. Request third-party load test certificates for critical applications. Bulk purchases (10+ sections) typically secure 15-25% discounts. Leading manufacturers provide CAD files for pre-event planning. Consider leasing options for occasional users to reduce capital expenditure.
