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

  • Page 4: Introduction

    0. Introduction The X i (X-Line Compact Install) loudspeaker systems represent an important step in line-array technology for small- and medium-scale sound reinforcement. The individual loudspeaker drivers, acoustic lenses, acoustic waveguides, enclosures and rigging hardware were all designed specifically for the X i product line to not only achieve the highest acoustic output with the highest fidelity, but also to produce a precise wavefront from each element to achieve state-of-the-art line- array performance.

  • Page 15: Rigging-Strength Ratings, Safety Factors, And Special Safety Considerations

    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 X are based on test results in which parts were stressed to failure. Manufacturers typically present the structural-strength ratings of mechanical components or systems as either the working-load limit (WLL) or the ultimate-break strength.

  • Page 16: Structural Rating Overview

    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 X follows: 1. The strength of each individual rigging point; which is the combined strength of the rigging frame, the rigging frame components (front button bars, rear swing arm, quick-release pins, etc.) and the enclosure.
  • Page 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 connector bars and the rigging plates relative to the enclosures.

  • Page 18: Complex Structural-Rating Analysis

    Figure 7 includes a graph of the working-load weight-versus-angle limit rating for the X 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.

    i-127, X i-127+ and X The actual strength of the X from each of the rigging points acting on the enclosure as a whole and will vary with the array configuration. However, for the sake of simplicity, Electro-Voice chooses to define the working- load limit of the overall enclosures as the sum total of the weight of that enclosure plus the weight of all of the enclosures and rigging hardware suspended below.

  • Page 25: Electro-Voice Structural-Analysis Procedures

    3.6 Electro-Voice Structural-Analysis Procedures Electro-Voice maintains a structural pull-test facility in Burnsville, Minnesota USA which includes load cells with digital-electronic display and recording. The load cells are calibrated annually by an independent laboratory to a standard traceable to the United States National Bureau of Standards. This pull-test facility is capable of pulling to destruction both individual rigging components and complete loudspeaker systems.

  • Page 26: Rigging Inspection And Precautions

    4. Rigging Inspection and Precautions Electro-Voice X i Loudspeaker Systems: Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components that could reduce enclosure strength. Inspect the rigging plates on the enclosures for any cracks, deformations, corrosion, missing or loose screws which could reduce the flying hardware strength.
  • Page 27 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. Always double check that each pull-up grid is securely bolted to the front connector bar assemblies and the rear connector bar assemblies on the X i enclosures before lifting.
