RIGGING Flashcards
What is the name and use of this?
P14 Motor Fly Cable - goes from motor distro to motor for power and control.
A P14 motor fly cable is a type of cable used in the entertainment industry to connect power distribution boxes to hoist control motors. It is a multi-pin connector that typically has 14 pins, and it is used to carry both power and control signals.
P14 motor fly cables are an essential piece of equipment for any theater, concert venue, or other event space that uses hoists. They are used to power and control a variety of equipment, including chain hoists, wire rope hoists, and motorized trusses.
turnbuckles can find their place in many professional, large-scale AV applications for several purposes:
- Rigging and Support:
Securing Trusses: In concerts, events, or studios, turnbuckles tension cables supporting trusses that hold lighting, sound equipment, and video screens. This ensures stability and prevents sagging under the weight of the gear.
Guying Masts and Towers: For outdoor AV setups, turnbuckles can tension guy wires stabilizing camera towers, speaker arrays, or temporary projection screens, resisting wind and ensuring safety.
2. Fine-Tuning Audio and Video Equipment:
Projector and Screen Mounting: Turnbuckles can finely adjust the tension of cables suspending projectors or screens, eliminating wrinkles and ensuring ideal alignment for optimal image quality.
Speaker Hanging and Alignment: In large sound systems, turnbuckles can adjust the angle and tension of speaker lines, achieving precise positioning for optimal sound distribution.
3. Specialized Applications:
Live Event Backdrops: Turnbuckles can tension cables holding fabric backdrops or projection surfaces, creating seamless and wrinkle-free presentation surfaces.
Studio and Stage Design: In theatrical or film sets, turnbuckles can adjust ropes or wires suspending props, curtains, or lighting elements, facilitating dynamic scenery changes.
Spigoted truss
A spigoted truss is a type of heavy-duty truss system characterized by its unique connection method using steel spigots. This specific connection style makes it stand out from other truss types and offers several key advantages:
Key features and benefits:
Fast and easy assembly: Unlike traditional bolt-together trusses, spigoted trusses use pins inserted into pre-welded sleeves (spigots) at the end of each tube. This eliminates the need for loose bolts and wrenches, significantly speeding up assembly and disassembly.
High strength and stability: The steel spigots provide a secure and rigid connection with minimal deflection, even under heavy loads. This makes spigoted trusses ideal for supporting large and heavy equipment like line arrays, video screens, and lighting rigs.
Versatility: Spigoted trusses come in various sizes and configurations, allowing them to be used for a wide range of applications in live events, from building stage roofs and supporting equipment to creating complex stage designs and effects.
Durability: The steel construction and robust connections make spigoted trusses highly durable and suitable for repeated use in demanding environments.
Here are some additional points to consider about spigoted trusses:
Cost: Compared to standard bolt-together trusses, spigoted trusses can be more expensive due to the specialized design and materials used.
Availability: While becoming increasingly common, spigoted trusses may not be as readily available as traditional truss types in all regions.
Weight: Due to the use of steel, spigoted trusses can be heavier than aluminum bolt-together trusses. This might be a factor to consider for portability needs.
Grapple
The Grapple allows you to make inline 90 degree connections between similar trusses anywhere along a perpendicular primary truss. The load capacity of the inline truss will carry 75 percent of the manufacturer’s load rating. The primary truss must have point load calculations taken into consideration. The secondary trusses must be supported at both ends. Cantilevering of truss is not recommended.
