Simplified Rating Guidelines

Figure 11 includes a graph of the working-load weight-versus-angle limit rating for the X-Line 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. The absolute enclosure angle is the vertical angle of that enclosure, where 0° represents an upright enclosure facing straight ahead (0° elevation angle). These working-Ioad- versus-angle limits take into account the complex forces generated in the front rigging straps, the rear rigging hinges, the enclosure and the (optional) pull-up line, as a result of the complex weight distribution throughout the array. Also included in the simplified structural-rating guidelines in Figure 11 are side-to-side and front-to-back angle limits for the front rigging straps on the top enclosure. These limits apply to the Xvsg and Xvsl rigging straps, as well as any custom rigging straps using the Xvsf fitting at the front of the top enclosure.
