The Use of Ratchet Straps in Entertainment Rigging
Ratchet straps are a versatile and essential tool in the world of entertainment rigging. Commonly used for securing loads in transportation and construction, these robust, adjustable straps are equally valuable in the fast-paced and safety-critical environment of stage, event, and circus rigging. Their strength, reliability, and adaptability make them indispensable for securing equipment, props, and structures during performances and events.
What Are Ratchet Straps?
Ratchet straps consist of a high-strength webbing material, typically polyester, attached to a ratcheting mechanism. The mechanism allows users to tighten the strap around an object securely and release it when needed. Ratchet straps are available in a variety of lengths, widths, and load ratings, making them suitable for a wide range of rigging applications. All ratchet straps used for entertainment rigging should be certified to local standards and regularly inspected according to local regulations.
Applications of Ratchet Straps in Entertainment Rigging
1. Securing Trusses and Structures
Ratchet straps are often used to stabilize and secure trusses, frames, and other structural elements. In temporary venues, such as outdoor stages or circus big tops.
Example:
• Anchoring truss towers to ground points to prevent toppling.
• Securing temporary staging platforms to prevent movement during performances.
2. Stabilizing Props and Scenery
Props and scenic elements used in performances often need to be secured to prevent accidental shifts or collapses. Ratchet straps can provide a reliable way to anchor these items without the need for permanent fixtures.
Example:
• Holding large props like set pieces or rigging structures in place.
• Attaching moving props to trolleys or platforms.
3. Suspending Loads
Although ratchet straps are not typically used as primary suspension points for dynamic loads (like performers), they can be used to suspend static loads such as trusses, lighting fixtures, sound equipment, or decorative elements.
Example:
• Connecting a performance of lighting truss to the tent or building structure
• Hanging static banners, screens, or curtains from trusses.
• Securing lightweight static equipment overhead.
4. Tensioning Components
The ratcheting mechanism allows for precise tensioning of materials like ropes, cables, or tarps, making them useful for stretching coverings or stabilizing frameworks.
Example:
• Tensioning backdrop fabrics or projection screens.
• Tightening guy wires or support cables for outdoor tents and structures.
5. Load Securing During Transport
Ratchet straps are indispensable for safely transporting rigging equipment, props, and staging elements to and from venues. Their high load capacity ensures that items remain secure during transit.
Example:
• Securing trusses, lighting rigs, and sound equipment in transport vehicles.
• Holding staging materials in place during long-distance travel.
Advantages of Ratchet Straps in Entertainment Rigging
1. High Strength-to-Weight Ratio
Ratchet straps are lightweight yet capable of handling substantial loads, making them ideal for portable setups where minimizing weight is important.
2. Ease of Use
The ratcheting mechanism allows for quick and secure tightening, saving time during setup and teardown. The release mechanism ensures that straps can be easily removed when needed.
3. Versatility
Available in a wide range of lengths, widths, and load ratings, ratchet straps can be used for a variety of purposes, from anchoring props to stabilizing trusses.
4. Cost-Effectiveness
Compared to more specialized rigging hardware, ratchet straps are relatively inexpensive, making them an economical choice for securing non-dynamic loads.
5. Weather Resistance
Polyester webbing used in most ratchet straps is moderately resistant to water, UV rays, and abrasion, making them suitable for both indoor and outdoor applications.
Safety Considerations for Using Ratchet Straps
1. Load Rating Compliance
Always ensure that the ratchet strap’s load rating matches or exceeds the expected load. Overloading straps can lead to failure, posing significant safety risks.
2. Inspect Before Use
Regularly inspect straps for signs of wear, such as fraying, cuts, or corrosion on the ratchet mechanism. Damaged straps should be replaced immediately.
3. Avoid Dynamic Loads
Ratchet straps are not designed to handle dynamic loads (e.g., aerial performers or moving equipment). Use purpose-built rigging equipment for such applications.
4. Proper Angle of Use
When anchoring or tensioning, ensure the straps are used at proper angles to prevent uneven loading or excessive strain on anchor points.
5. Secure Anchor Points
Verify that anchor points (e.g., ground stakes, trusses, or fixtures) can handle the forces applied by the ratchet straps without failing.
Conclusion
Ratchet straps are an invaluable tool in entertainment rigging, offering strength, versatility, and reliability in securing loads, stabilizing structures, and tensioning materials. While they are not suitable for all applications, their wide range of uses makes them indispensable for stage, circus, and event setups. By selecting the right strap for the job and adhering to safety guidelines, riggers can ensure that these essential tools contribute to both the safety and success of every performance.
