Singer Yu Jiayun’s Live Concert | YZDITEC 41-Point Synchronized Rigging Rental Case

41-Point Synchronized Rigging System: Yu Jiayun Live Concert

Concert rigging rental projects rarely throw all the curveballs at once. This one did.
Project Specs: 41 servo hoists | 30-point LED rig (24 m × 24 m) | 5 lighting trusses | 1 art installation | Single-console control

1.  The Brief

Singer Yu Jiayun's live concert required 41 independent suspension points—each with different load profiles and motion requirements. The centerpiece: a 24 m × 24 m four-sided LED screen suspended from 30 synchronized points. Add lighting trusses (10–20 m), a suspended sphere, and coordinated lift-tilt-stagger choreography throughout the show.

For stage automation teams and rental companies, this multi-point complexity is where traditional manual systems hit their limits.

2.  The Challenge: Precision at Scale

Two non-negotiables drove the rigging system design:

Sync precision — 30 hoists moving a 576 m² LED assembly can't drift by millimeters. Any phase mismatch would twist the structure or trigger emergency stops.

Load stability — Variable payloads across 41 points required independent torque control and real-time monitoring to prevent sway or overspeed during transitions.

3.  The Solution: One Console, 41 Motors, Zero Surprises

We deployed 41 BGV C1-certified servo chain hoists, orchestrated through a single automation console with 3D simulation and offline programming.

Pre-show workflow:

• Venue mapping and load distribution modeled in 3D simulation
• All sequences programmed offline and tested virtually
• Safety limits pre-configured per rigging point

Show-night execution:

• Real-time position and load monitoring across all motors
• Multi-axis moves triggered from single cue commands
• Automated safety warnings flagged deviations before they became visible

The entire stage rigging system ran as a unified machine—not 41 individual hoists hoping to stay in sync.

Performance: Tight Moves, Zero Drama

Every programmed sequence executed within spec. The LED screen lifted, tilted, and repositioned without drift. No emergency stops. No manual interventions.

For a rental deployment in a live concert environment, that's the standard we build to.
