Figure 11:
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.
