Setting Up a Professional Concert Stage: Step-by-Step Truss Assembly Guide

Before any metal touches the ground, verify your floor plan. Ensure the ground is level and can support the point loads of the towers. Clear the area of unauthorized personnel and conduct a full safety briefing.

Step 2: Base Plate and Outrigger Placement

Lay out heavy-duty steel base plates. For outdoor setups, always use outriggers (stabilizers) to increase the tower footprint. Level the base plates using adjustable screw jacks for a perfectly vertical lift.

Step 3: Tower Assembly

Connect the hinge section to the base plate — this allows you to assemble the truss tower horizontally on the ground and tip it up safely. Attach the sleeve block to the hinge.

Step 4: Horizontal Truss Connection

• Insert spigots into the chord ends.
• Align the holes and drive tapered pins through with a copper hammer (never steel — it damages aluminum).
• Critical: Secure every pin with an R-clip immediately. Never leave a pin unclipped.

Step 5: Hoisting and Rigging

Attach chain hoists to the top section and connect chains to the sleeve blocks. Perform a cross-check before lifting — all connections tight, all pins clipped, no tools left on the truss.

Step 6: The Lift

Lift slowly and evenly. If using multiple motors, ensure synchronization to avoid uneven torque. Once at height, dead-hang the truss or use safety cables as required by local regulations.

Common Mistakes to Avoid

• Mixing Brands: Never mix truss from different manufacturers — minor tolerance variations cause structural failure.
• Overloading: Always consult the Fengsheng load chart for your specific span length.
