ELECTRO-VOICE ® 2 Rigging-Safety Warning This document details general rigging practices appropriate to the entertainment industry, as they would apply to the rigging of Electro-Voice XLC loudspeaker systems. It is intended to familiarize the reader with standard rigging hardware and techniques for suspending XLC loudspeaker systems overhead.

ELECTRO-VOICE ® 5 1. XLC Rigging System 1.1 Overview of the XLC Flying System The XLC loudspeaker systems have been designed to construct acoustic line arrays. Acoustic line arrays typically consist of independent columns of loudspeaker systems. This simplifies the rigging system.

ELECTRO-VOICE ® 7 Specifically, this means that when the enclosures are suspended, the back of the bottom enclosure will rotate down until the pin is stopped at the end of the slot in the swing arm. This one pin will not prevent the back corners of the enclosures from coming together.

ELECTRO-VOICE ® 10 2. XLC Rigging and Flying Techniques 2.1 Array Considerations The XLC loudspeaker systems have been specifically designed to construct acoustic line-arrays. Line-array systems typically consist of independent columns of loudspeaker enclosures.
ELECTRO-VOICE ® MAKE SURE THAT THE SPRING-LOADED BUTTONS ON THE BUTTON BARS FULLY LOCK INTO THE ROUND HOLES IN THE FRONT RIGGING TUBES ON BOTH ENCLOSURES. REPEAT THIS FOR EVERY ENCLOSURE ON BOTH SIDES OF THE LINE ARRAY. Attach the top enclosure in the array to the grid, as shown in Figure 6c.
ELECTRO-VOICE ® 12 Initially, the rear rigging will be slack as the array is lifted. As more enclosures are suspended, the rear swing arms in the top enclosures will go into tension.

ELECTRO-VOICE ® 3. Rigging-Strength Ratings, Safety Factors, and Special Safety Considerations 3.1 Working-Load Limit and Safety Factor Definitions The structural ratings for all of the XLC rigging components and complete loudspeaker systems are based on test results in which parts were stressed to failure.
ELECTRO-VOICE ® 16 3.2 Structural Rating Overview There are two independent strength ratings that, together, give a complete description of the overall structural performance capabilities of any XLC loudspeaker system. They are defined as follows: 1.
ELECTRO-VOICE ® 17 These guidelines provide a simplified rating for typical arrays based on the: 1. Vertical angle of each enclosure 2. Total weight of that enclosure plus all of the enclosures and rigging hung below it. 3. Angles of the force components on the front button bars and the rigging frames relative to the enclosures.
ELECTRO-VOICE ® 18 Figure 7 includes a graph of the working-load weight-versus-angle limit rating for the XLC enclo- sures. This working-load weight limit is applicable to every enclosure in an array, and includes the weight of that enclosure plus the total weight of all enclosures and rigging hardware suspended below it.
ELECTRO-VOICE ® 19 The reader should consult an experienced structural engineer to perform the complex structural analysis. WHEN SUSPENDING ANY XLC LOUDSPEAKER SYSTEM OVERHEAD, THE WORKING-LOAD LIMITS MUST NEVER BE EXCEEDED FOR EACH INDIVIDUAL RIGGING POINT, AND THE OVERALL ENCLOSURE.

ELECTRO-VOICE ® XLC-127, XLC-127+ and XLC-118 Overall Enclosure Structural-Strength Ratings The actual strength of the XLC enclosures will depend on the complex total of the combined forces from each of the rigging points acting on the enclosure as a whole and will vary with the array configuration.

ELECTRO-VOICE ® 26 4. Rigging Inspection and Precautions Electro-Voice XLC Loudspeaker Systems: Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components that could reduce enclosure strength.
ELECTRO-VOICE ® Pull-Up Grid Assemblies: Prior to each use, inspect the pull-up grid bar assembly any for cracks, burrs, deformations, corrosion or missing or damaged components that could reduce the pull-up assembly strength. Replace any pull-up grids that are damaged or missing hardware.
