How to Rig and Fly Line Array Speakers Safely

How to Rig and Fly Line Array Speakers Safely

Overview and intent

Rigging and flying line array speakers demands engineering awareness, certified hardware, and an experienced crew. This guide explains how to plan and execute safe lifts and long-term suspensions for line array speakers so events run smoothly and risks are minimized.

Understand project scope and coverage needs

Assess venue, audience and coverage

Start by confirming the venue type (indoor/outdoor), audience size, sight lines and acoustic goals. A flown line array delivers even coverage across distances; choosing the correct number and orientation of line array speakers is the first safety and performance step. Knowing the system layout early prevents mid-rig changes that can compromise safety.

Calculate loads and plan the lift

Determine module weights and total array load

Collect exact weights and rigging point data from your line array speakers' manufacturer specs. Add accessories such as fly frames, rigging hardware, cabling, and weather covers to compute the total suspended mass. Always plan using the maximum expected weight. Underestimating weight is a common and dangerous mistake.

Typical module comparison

Below is a typical comparison to help planning—verify your specific product weights and rigging details with the manufacturer and product manual before use.

Apply safety factors and working load limits

Use certified Working Load Limit (WLL) values stamped on hardware. Industry practice is to use a safety factor—commonly at least 5:1—for temporary suspensions; many professionals prefer 7:1 or greater for added margin on long-term or permanent installs. This means that the hardware’s breaking strength should be at least 5–7 times the expected static load. Include dynamic load allowances for wind, crowd‑induced vibrations and rigging adjustments.

Select certified rigging components

Choose hoists, shackles, slings and frames

Only use rigging components certified to recognized standards (CE, GS, EN, ASME or equivalent), with visible load ratings and traceable certificates. Typical items include motorized chain hoists with appropriate WLL, certified shackles, bonded steel slings or splice eyes, flying frames specific to your line array model, and secondary safety cables. Never mix unknown or homemade hardware into a flown system.

Cable management and electrical hardware

Use rated cable tray or tamer straps for audio and power runs; avoid using signal cabling for load-bearing. Power distribution should be planned to avoid overloading circuits. All hoists and electrics must be inspected and tagged according to local regulations.

Step-by-step rigging procedures

Pre‑rig inspection and planning meeting

Hold a pre‑rig safety meeting with all crew—rigger, hoist operator, speaker tech, site manager and safety officer. Review lift plan, weight calculations, hardware certificates, emergency procedures, and communication signals. Inspect all components: look for wear, deformation, corrosion, missing markings, and proper lubrication on hoists. Remove any suspect equipment immediately.

Trial assembly on ground (ground stacking test)

Assemble the array on the ground first to confirm rig geometry, correct splay angles and audio alignment. Verify that the fly frame mates with each module as intended and that rigging pins, locks and safety catches function properly. Ground testing helps find interference and balance issues safely.

Attach safety backups and secondary restraints

Each flown array should have a secondary safety restraint such as a certified steel safety cable or redundant shackles routed independently of the primary rigging path. This backup is required wherever speakers are flown over people. Safety chains or retention cables must be rated and installed following manufacturer guidance.

Executing the lift and trim

Use qualified, certified hoist operators. Lift slowly and smoothly, watching for unexpected load shifts. Keep nonessential personnel clear of the area beneath the lift until the array is secured and safety inspections are complete. Trim the array to the desired height and angle, then torque and lock all rigging pins and bolts per manufacturer torque specs.

Operational safety and environmental considerations

Weather, wind and outdoor risks

Wind is a primary hazard for flown line arrays outdoors—gusts create large dynamic loads and can change array behavior. Follow manufacturer wind limits and local regulations. Lower or secure flown arrays before forecasted high winds or storms. Consider using wind fences, anchor redundancy and real‑time monitoring when conditions are marginal.

Crowd protection and exclusion zones

Establish exclusion zones under and around flown loads. Barriers and signage keep the public clear. For events with a crowd beneath a flown array, ensure all secondary safety systems are in place and documented. Coordinate with event management and local authorities for compliance.

Inspection, maintenance and documentation

Routine checks and recordkeeping

Inspect rigging points and hardware before and after each flight. Maintain records of certificates, inspection tags, torque values, and any maintenance work. Schedule periodic load tests and replace hardware per manufacturer service intervals or when wear is detected. Good documentation supports safety and legal compliance.

Frequently Asked Questions (FAQ)

Do I need certified riggers to fly line array speakers?

Yes. Certified riggers and qualified hoist operators are required for safe aerial installations. Certification ensures familiarity with load calculations, hardware limitations and emergency procedures.

What safety factor should I use when calculating loads?

Use at least a 5:1 safety factor as a minimum; many professionals opt for 7:1 or higher for long‑term or public‑space suspensions. Always follow manufacturer guidance and local regulations.

How often should rigging hardware be inspected?

Inspect before every use and perform scheduled detailed inspections per manufacturer and local standards. Replace any hardware that shows deformation, cracks, corrosion, or compromised markings.

Can I fly speakers in light rain?

Only if the line array and its rigging are rated for outdoor use and weather protection. Water can add weight and change load dynamics; avoid flying in rain unless equipment is explicitly weather‑resistant and wind conditions are within safe limits.

What is the role of a secondary safety cable?

A secondary safety cable acts as a redundant restraint if the primary rigging fails. It is mandatory when flying speakers over people or in many public venues.

Who should I contact for rigging specs for a specific line array model?

Contact the manufacturer or authorized dealer. For T.I Audio products, consult the technical documentation provided with each line array speaker or reach out via https://www.ti-audio.com/ for certified rigging data.
