Aerial Hoop: Mounting, Safety, and Installation Guide

How Do You Mount an Aerial Hoop?

Mounting an aerial hoop, also known as a lyra, is a complex process that demands meticulous attention to structural integrity, equipment selection, and rigging principles to ensure the safety of the practitioner. It involves securing a robust overhead anchor point, assembling a certified rigging system, and attaching the hoop itself, all while adhering to strict safety protocols and load limits.

Understanding the Aerial Hoop System

An aerial hoop setup is more than just the hoop itself; it's a complete system designed to safely support dynamic human movement. Understanding each component is crucial for proper installation and safe use.

• The Aerial Hoop (Lyra): Typically made from hollow or solid steel tubing, shaped into a circle, and often powder-coated for grip and aesthetics. Hoops come in various diameters and thicknesses.
• Anchor Point/Rigging Point: This is the overhead structural element to which the entire system is attached. It must be able to withstand significant static and dynamic loads. Common anchor points include exposed steel beams, reinforced concrete ceilings, or purpose-built rigging trusses.
• Rigging Hardware: A collection of specialized components that connect the hoop to the anchor point. This includes:
  • Carabiners: Load-bearing connectors, often made of steel, with a spring-loaded gate. Only use locking carabiners rated for aerial use.
  • Swivels: Devices that allow the hoop to rotate freely, preventing twisting of ropes or straps, and reducing torque on the anchor point.
  • Slings or Straps: Strong, flat webbing or round slings used to create attachment points or extend rigging, often around beams.
  • Rescue 8 / Figure 8 / Descenders: Devices used to create the connection point for the hoop, allowing for height adjustment.
  • Quick Links: Permanent or semi-permanent connectors, often used for static connections.
• Suspension System: The specific configuration of slings, ropes, or chains that connect the rigging hardware to the hoop. This can be a single-point attachment (most common) or a two-point attachment.

Prioritizing Safety: A Non-Negotiable Foundation

Safety is paramount when setting up any aerial apparatus. Neglecting proper installation can lead to severe injury or fatality.

• Structural Integrity Assessment: Before any installation, the proposed anchor point must be rigorously assessed by a qualified professional (e.g., a structural engineer, certified rigger, or experienced aerial arts professional). They will determine if the structure can safely support the required static load (the weight of the hoop and the performer) and, more critically, the dynamic load (the forces generated by movement, swings, and drops, which can be several times the performer's body weight). A general rule of thumb for dynamic loads in aerial arts is to multiply the static load by a factor of 5-10.
• Weight Limits and Working Load Limit (WLL): Every component in the rigging system (carabiners, swivels, slings, the hoop itself) has a Working Load Limit (WLL) and a Minimum Breaking Strength (MBS). Always ensure that the WLL of every single component exceeds the maximum anticipated dynamic load. It is best practice to use components with a Safety Factor of at least 7:1 or 10:1 (MBS divided by WLL).
• Redundancy: Whenever possible, incorporate redundancy into your rigging system. This means having backup components or systems so that if one fails, another can still support the load. For example, using two carabiners where one might suffice, or a backup safety line.
• Professional Consultation: For home installations, especially, consulting or hiring a professional rigger or structural engineer is highly recommended. Do not attempt to guess the strength of your ceiling joists or beams.

Step-by-Step Installation Guide

Assuming a suitable and professionally assessed anchor point is available, here's a general guide to mounting an aerial hoop. This is a simplified overview; specific setups may vary.

1. Identify a Suitable Mounting Point: As discussed, this must be a professionally verified overhead structural element capable of bearing significant dynamic loads. Examples include exposed steel I-beams, reinforced concrete, or a professionally installed rigging truss system. Avoid attaching to standard ceiling joists, drywall, or unsupported wooden beams.
2. Install the Anchor Point Attachment:
   • If using an exposed beam, a properly rated beam clamp or round sling wrapped securely around the beam is often used.
   • For concrete, a drilled and rated eye bolt or anchor plate may be installed. This requires specialized tools and expertise.
   • Ensure all bolts are torqued to specification and all connections are secure.
3. Assemble the Rigging System:
   • Attach the primary rigging component (e.g., a rescue 8, figure 8, or a specialized aerial descender) to the anchor point attachment using a locking carabiner.
   • If a swivel is desired for rotational movement, it is typically placed between the primary rigging component and the hoop, connected with locking carabiners on both ends.
   • For a single-point hoop, the rigging system typically ends with a single strong connection point for the hoop. For a two-point hoop, the rigging system will branch into two connection points.
   • Ensure all carabiner gates are locked and facing the correct direction (spine loaded, not gate loaded).
4. Attach the Aerial Hoop:
   • Connect the hoop to the bottom of your assembled rigging system using a final locking carabiner.
   • For single-point hoops, there is usually a single tab or connection point on the hoop itself. For two-point hoops, there are two tabs.
   • Double-check that all connections are secure and all carabiners are locked.
5. Perform Load Testing:
   • Before anyone uses the hoop, it is crucial to perform a load test.
   • Gradually apply weight to the hoop, starting with light pressure and progressively increasing to the expected maximum dynamic load. This can be done by hanging progressively heavier weights (e.g., sandbags) or by having a spotter slowly apply their weight.
   • Monitor the entire system for any signs of strain, creaking, shifting, or deformation. If anything seems amiss, stop immediately and re-evaluate the entire setup.
   • A common practice is to have the lightest person test the setup first, performing gentle movements, before progressing to more dynamic actions or heavier users.

Essential Equipment and Materials

Beyond the hoop itself, you will need:

• Certified Aerial Hardware: All carabiners, swivels, slings, and other connectors must be rated for aerial use (often marked with UIAA, CE, or EN standards) and have a clearly stated WLL and MBS.
• Measuring Tape: For accurate height adjustments.
• Wrenches/Tools: For tightening bolts on beam clamps or other hardware.
• Ladder: A stable, tall ladder suitable for working overhead.
• Crash Mat: Essential safety equipment to place directly underneath the hoop, providing cushioning in case of a fall. The mat should be thick and cover a sufficient area.
• Spotter: Another person to assist with the installation and initial load testing.

Ongoing Inspection and Maintenance

Once installed, the aerial hoop system requires regular inspection to maintain safety.

• Pre-Flight Checks: Before every use, visually inspect all components:
  • Are all carabiners locked?
  • Are there any signs of wear, fraying, or damage on slings or ropes?
  • Are there any deformations, cracks, or rust on the hoop or metal hardware?
  • Is the anchor point still secure?
• Regular Detailed Inspections: Perform more thorough inspections weekly or monthly, depending on frequency of use. Check for:
  • Loose bolts or connections.
  • Wear patterns on hardware that might indicate friction points.
  • Integrity of the hoop's welds or coating.
  • Any changes to the supporting structure.
• Component Replacement: Replace any component that shows signs of wear, damage, or has exceeded its recommended lifespan, even if it appears minor.

When to Seek Professional Assistance

While this guide provides an overview, there are many situations where professional help is not just recommended, but essential:

• Uncertainty About Structural Integrity: If you are unsure about the strength of your ceiling, beams, or any potential anchor point.
• Complex Rigging Setups: For multi-point systems, custom installations, or permanent studio setups.
• Lack of Specialized Tools or Knowledge: If you don't have the proper tools (e.g., for drilling into concrete) or the knowledge of rigging principles.
• Any Doubts or Concerns: If you feel any apprehension about any part of the installation process. Your safety is paramount.

Conclusion: Rigging with Precision and Prudence

Mounting an aerial hoop is a serious undertaking that marries the art of aerial performance with the science of engineering and safety. It requires a deep respect for physics, a meticulous approach to installation, and an unwavering commitment to safety protocols. By understanding the components, prioritizing structural integrity, and not hesitating to consult with qualified professionals, you can create a secure environment for the exhilarating and challenging practice of aerial arts.
