[. . . ] The user is cautioned that some local regulations may require safety factors higher than 7:1. In that circumstance, Electro-Voice insists that the user maintain the higher safety factor as required by the local regulations throughout the entire XLCi installation. It is the responsibility of the user to make sure that any XLCi installation meets any applicable local, state or federal safety regulations. ELECTRO-VOICE® XLCiTM Rigging Manual 14 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 XLCi loudspeaker system. 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. The total strength of the overall enclosure; which is a function of the combined forces from all of the rigging points acting on the rigging frames and enclosure as a whole. The array designer must be aware of the working-load-limit ratings and the loads being applied to the individual rigging points and the overall enclosure. It is usually the case that one of the working-load limits will be approached sooner that the other. WHEN SUSPENDING ANY XLCi LOUDSPEAKER SYSTEM OVERHEAD, THE WORKING-LOAD LIMITS MUST NEVER BE EXCEEDED FOR EACH INDIVIDUAL RIGGING POINT, OR THE OVERALL ENCLOSURE. The forces acting on each individual rigging point and on the overall enclosures in an XLCi flying system will vary with each array configuration. Determining the forces throughout an array requires complex mathematical calculations. Electro-Voice engineers have, however, defined a set of simplified structural-rating guidelines that eliminate the need for the complex calculations for most array configurations. The interaction of the complex forces throughout arrays were analyzed to develop this set of conservative guide-lines, presented below, to enable a rigger to immediately determine on site whether or not an array is safe without having to make weight-distribution calculations. The structural-strength ratings of the individual rigging points and the overall XLCi enclosures are also presented below so that a complex structural analysis can be made for any array configuration. The reader should consult an experienced structural engineer to perform the complex structural analysis. The reader is directed to the References section of this manual for a list of rigging references (for background in general rigging practice) and mechanical engineering references (for background in structural engineering analysis). 3. 3 Simplified Structural-Rating Guidelines Electro-Voice engineers have defined a set of simplified structural-rating guidelines that will enable a rigger to immediately evaluate the safety of an XLCi system on site without having to make complex force-distribution calculations. A combination of destructive testing and computer modeling were used to analyze the complex forces throughout arrays. Conservative working-load ratings were utilized to simplify the guidelines. Therefore, array configurations other than those illustrated in these simplified guidelines may be permissible for those applications, consult section 3. 4 Complex Structural-Rating Analysis for a detailed structural analysis. (Note that there is a label on the back of each flying XLCi loudspeaker enclosure that includes the graphics shown in Figure 7. ) 15 ELECTRO-VOICE® XLCiTM Rigging Manual These guidelines provide a simplified rating for typical arrays based on the: 1. Total weight of that enclosure plus all of the enclosures and rigging hung below it. Angles of the force components on the front connector bars and the rigging plates relative to the enclosures. Angles of the force components on the rear connector arms and rigging plates relative to the enclosures. Figure 7: Simplified X i Rigging-Rating Guidelines LC ELECTRO-VOICE® XLCiTM Rigging Manual 16 Figure 7 includes a graph of the working-load weight-versus-angle limit rating for the XLCi enclosures. 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. [. . . ] Never exceed the limitations or maximum recommended load specified by the hoist manufacturer. Always follow manufacturers' recommendations for operation, inspection, and certification. Always raise and lower the load slowly and evenly, avoiding any rapid changes in speed or shifting loads that could result in a sudden jolt to the suspended system. Building, Tower or Scaffold Supports: Prior to each use, the strength and load-bearing capabilities of the building, tower or scaffold structural supports should be evaluated and certified by a professional engineer as being adequate for supporting the intended rigging system (including the loudspeakers, grids, chain hoists and all associated hardware).
